Do-it-yourself gur nexia pump repair

In detail: do-it-yourself gur nexia pump repair from a real master for the site my.housecope.com.

12 closed type 6203DKA2
I bought 6203 skf 235 rubles, and 500 re for the service.
The strangest thing is that the bearing is evidence and it feels alive, the internal pump is also normal. Vague doubts plagued ((
In general, I'm waiting for the gur to be returned))

This is a complete failure. The whole rumble was from the one-year-old belt leakage.

The belt that rotates the generator and the gur made the hellish sounds of a collapsed bearing, with a distinct rumble of rollers inside the rolled bearing.
I put a repair gur, but the sound did not disappear. I sprinkled it in a box, and there was silence for 30 seconds. I put a new belt of a different brand and silence. I'm just out. 2100 rubles wasted for nothing.

I could not even think that the belt could make such sounds.

I will tell you how I repaired the power steering pump. But first, a little background.

The steering wheel on a cold car in summer and winter works flawlessly. But as soon as the car warms up, especially in the summer, the steering wheel on the XX becomes very tight, as if the power steering is not there. In winter, this problem does not manifest itself so strongly, but it is still present. If you put it on the gas, the steering wheel immediately turns with ease (though not quite ideal, but still lighter). At the same time, the pump does not knock, does not ring, nor leaks, etc ... (do not take the snotty rail into account) the oil is fresh and perfect (especially, thanks to the state of the rail, it is updated regularly!), The cardan is lubricated and does not wedge!

Video (click to play).

In general, on the face of the sign of the lack of performance of the power steering pump with hot oil at XX. I didn't suffer for a long time, in the end I decided to deal with this problem, spent a lot of time, rummaged through the Internet, understood the principle of the pump, found a similar description and decided to sort out my "old" pump.

And so, first of all, we remove the pump, it is necessary to drain all the slurry from it (how to remove it and drain the liquid, I think everyone will figure it out), also, on the back cover of the power steering, you need to unscrew four bolts with a 14 head.

After we begin to carefully remove the cover, try not to damage the gasket (this gasket with an internal rubber seal), in the power steering body we leave the outer part of the "working ellipse cylinder" (hereinafter simply the cylinder). There is no need to be scared when the lid moves away from the case, it may seem that it is moving away due to the influence of the spring, during reassembly it will seem to you that it does not fit into place, just continue to carefully and alternately tighten the bolts diagonally, then everything will fall into place ...

Carefully inspect the contents and remember (you can take a photo) what stood where and how (more attention should be paid to the position of the cylinder). You can twist the power steering pulley and gently check with tweezers how the blades move in the grooves of the shaft.

All parts should be pulled out without effort, since they do not have any fixations, but the central axis is fixed rigidly, it cannot be removed.

We inspect the shaft from the back side, parts (power steering body and cover wall) touching them, for scoring or grooves, everything is perfect for me.

Now we take out the entire internal economy on "clean" rags and begin to study it.

We carefully examine the shaft, all its grooves have very sharp edges on all sides.One of the end sides of each groove has a pronounced sharpening inward, which, when the blade moves inside the groove with a constant slope to this side, will greatly complicate its movement (this may be the first component of the poor operation of the power steering). The lateral parts of the grooves of the shaft are also "sharpened", this can be felt if you slide your finger in different directions along the end (outer circumference), as well as along the lateral parts of the shaft in different directions. The rest of the shaft is perfect, does not have any flaws and notches.

The faults were found, now we are starting to eliminate them.

We need a rag, white alcohol, sandpaper with a grit of P1000 / P1500 / P2000, a triangular file, a 12mm drill (or more) and an electric drill. With the shaft, everything is much simpler, you need a P1500 sandpaper and we begin to clean all the edges of the grooves on the shaft (we clean the outer and lateral on both sides) in all possible ways. We work without fanaticism, the main task is to remove only sharp burrs.

For one thing, you can immediately polish both sides of the shaft on a flat surface, it is advisable to use P2000 sandpaper.

Next, you need to check the result of our work, check it visually and by touch, everything is perfectly smooth and does not cling.

The most difficult thing will have to do with the surface of the cylinder, I personally have nothing simpler, I have not figured out how to make a spherical grinder from a skin, a drill and a thick drill (F12). To begin with, we take a P1000 skin and such a drill, which can be crammed into a drill.

Next, you need to tightly wind the skin against the rotation of the drill, in two or three turns, there should be no gaps.

Holding the tightly twisted structure, you need to insert it into the drill (clamp the skin too).

Then, in the most convenient ways for you, we carefully begin to grind the cylinder, you need to grind evenly, press the cylinder tightly and move it relative to the axis of rotation (at maximum speed). As the skin is eaten, we change it, as a result we reach the smallest skin P2000.

The desired result is obtained,

now everything must be thoroughly wiped with a path with white alcohol. The shaft itself with blades can be rinsed in it.

After we start the assembly, everything is put in the reverse order of removal.

Over the years, cars have received many additional systems that provide driving comfort. One of them is the power steering, which is now installed not only on expensive cars, but also on some configurations of the budget Daewoo Nexia.

The power steering itself is very convenient, with it the steering wheel turns incredibly easily and even during long trips around the city, your hands do not get tired. But, like any other, moreover, it is quite complex and highly loaded, the mechanism, the hydraulic booster requires periodic maintenance and is subject to a number of possible breakdowns.

Modern power steering consists of a fluid circuit, a reservoir, a pump and a hydraulic unit. It can also use electronic control units that allow you to distribute the load more intelligently, depending on the speed of the car (the slower - the more effort). The hydraulic unit consists of a double-sided cylinder with a piston, it is connected directly to the steering bipod.

With straight motion, the oil in the system constantly circulates in a circle without creating pressure on the piston. But when you turn the steering wheel, the rotary valve also moves, which changes the distribution of oil on both sides of the piston.On the one hand, the pressure is built up, and from the other, the oil is pumped out into the reservoir. The increased hydraulic pressure displaces the piston, which presses against the steering arm and removes some of the force from the steering wheel.

Schematically, the system in Daewoo is relatively simple, but all of its elements operate under high load, which leads to relatively frequent leaks of hydraulic fluid. Also, the pump or its individual elements, for example, a belt, may fail.

Power Steering Hydraulic Pump for Daewoo Nexia

The most common problem with power steering on Daewoo Nexia is oil leakage. Periodically, oil seals rot or wear out in the system, from where oil begins to leak. In fact, almost all power steering systems are subject to a similar problem.

Drivers often do not pay attention to small leaks in a couple of drops of oil. But any small leak will sooner or later develop into a full-fledged leak, and you may be left without hydraulic fluid in the middle of the road, which will lead to damage to the pump and generator.

The Daewoo Nexia has two standard power steering leaks: in the pump area and near the pedals, at the driver's feet. In the case of a pump, you need to accurately find the place of the leak, it can be both the hoses and their connections, and the pump itself, then you will have to disassemble it and change the gaskets. And if a leak is found in the area of the pedal assembly, then you need to buy a set of new oil seals and replace them.

Another popular problem is pump failure. There may be many reasons, but the pump is simple in design, easily disassembled and you can either replace it completely or purchase individual parts.

Belt leading to the power steering pump on Daewoo Nexia

Also, when turning the steering wheel on Daewoo Nexia, noise or whistling may appear. This problem is definitely related to the power steering, but it is not always possible to determine the source of the noise. First of all, you need to check the belt leading to the pump. It could sag, wear out or get dirty in oil, which causes slippage, in which case everything is solved by replacing. If it's not about the belt, then it's worth checking the pump bearing.

The power steering requires certain maintenance, in particular, you need to periodically change the fluid. The difficulty is that the exact mileage figures for Daewoo are not indicated anywhere. Many drivers drive 100 thousand kilometers or more, but this is not recommended, the community of Nexia owners agreed that the fluid needs to be changed every 50 thousand kilometers.

The procedure is relatively simple, you will need a set of simple tools (wrenches, pliers, screwdrivers), a few empty dishes, rags and gasoline. You also need hydraulic fluid or transmission oil for automatic transmissions.

When replacing, you need to raise the front of the Nexia, open the hood and find the power steering fluid reservoir. You can drain the oil from it in two ways - immediately disconnect the pipe and quickly substitute a relatively large vessel so that oil does not flood the entire engine compartment. But motorists recommend buying a rubber bulb at the pharmacy and pumping out the oil from the tank with it, and only then disconnecting the hoses, so there are less risks.

Changing fluid in power steering Daewoo Nexia

After the oil has been drained, the system hoses must be immediately put into a collection container and, with the engine turned off, turn the steering wheel in both directions until it stops, this will help drain the oil from the circuit.

It is best to rinse the removed tank with regular gasoline. It is worth noting that there is a filter inside the Nexia tank, it cannot be removed, but it can be unscrewed and washed inside the tank.

Then you need to return the tank to its place, connect the hoses and fill in new fluid to the maximum mark. After that, you need to turn the steering wheel of your Daewoo from stop to stop again, some of the oil will go away and you will need to add more, and then turn the steering wheel again. If the level has dropped again, top up again to max (the liquid level must be watched with the wheels aligned exactly).But this is not all, after the oil is poured, you need to start the car and turn the steering wheel again from lock to lock and check the level again.

First, take a look at the air filter housing.Then remove the accessory drive belt.And with a 12 key, unscrew the three bolts securing the power steering pump pulley.Using a 16 key, unscrew the union and disconnect the pressure pipeline from the pump.weaken and move the hose clamp of the supply line.Using a 12 key, unscrew the two pump mounting bolts.Then we move the pump slightly to the side and disconnect the hose of the supply pipeline.

Daewoo Nexia has a long history. The direct successor of Opel Kadett, this model of the Korean car industry is currently produced in Uzbekistan. Over the entire production period, the model has "grown" by only one generation, but it still remains one of the most demanded in the Russian and CIS markets. Due to the great age of many cars, the issue of repair, and in particular the repair of the Daewoo Nexia power steering, is relevant.

Complete diagnostics of the STEERING RACK.

If we make repairs, then this is included in the cost of work.

The specific cause of the breakdown can only be named after a thorough technical inspection of the car. But, as a rule, most of the breakdowns are due to untimely maintenance, poor-quality repair of the Daewoo Nexia power steering, or simply due to the great age of the parts themselves. After all, the model has been produced since 1994.

It is impossible to describe all types of breakdowns, but here are the most relevant ones:

Replacing the power steering fluid. This item is the leader among all brands and models of cars. The situation is aggravated by the fact that the official Daewoo Nexia manual does not have an exact answer when it is worth changing the fluid, which is why some drivers do not make a replacement at all. The results are quite deplorable - an expensive repair of the Daewoo Nexia power steering with a complete replacement of all parts.
Steering rack corrosion. Another known problem for the owners of this car. It manifests itself in a tight turn of the steering wheel, it is often eliminated without replacement, only good cleaning is required.
Leaking in the cistern. The main source of this failure is a worn out gland, or a damaged hose. Both at the service station will be replaced quickly and inexpensively.
Knock when turning the steering wheel. A very popular problem, the solution to which lies in the replacement of bushings and worm gear.

Most minor breakdowns can be repaired on their own, sometimes even without a special tool. But do not forget about regular maintenance, as well as trying to independently repair complex control systems, such as a power steering. Improper repairs will not only take your time, but can also lead to further breakdowns, which will eventually lead you to the service station. service, but you will have to pay a large amount.

Motorists know how much nerve is wasted when power steering problems appear. The steering wheel behaves strangely and turns much more difficult at idle or low revs. A whistling sound is heard from the pump bearing. Leakage of working fluid onto the engine or onto the road at the location of the unit. The rotation of the steering shaft is accompanied by extraneous sounds.

These inconveniences can affect not only the nervous health of the driver, but also driving safety. What to do if the pump shows symptoms of malfunctioning? How to replace this power steering part? Is it possible and how to carry out the repair work yourself? We will tell you more about everything below.

The manifestations of pump breakdowns described above, in reality, may not be associated with the pump itself. Therefore, first you need to carefully examine the entire power steering system. And only if the problem is not found, start working with the pump itself.

Faults are divided into two types:

mechanical damage and wear. These include burrs, bearing problems, bumps in the interior, wear on the gasket, etc .;
hydraulic problems. Associated with insufficient fluid levels, improper fluid selection and aging. The ingress of debris into the system can also lead to the appearance of "symptoms", and, in the future, to breakdown. Banal airing refers to the same type of malfunction.

The former can only be determined by disassembling the power steering pump and inspecting each of its components. As for the second type of malfunctions, first of all, you need to answer the questions - how much time has passed since the fluid in the system was changed? Was the fluid selected according to the instructions? Is its level sufficient? And in case of airing, it is often enough to pump the hydraulics to restore the power steering.

In any case, manufacturers recommend doing a full bulkhead and cleaning if any problems arise with the pump. This will help reduce the likelihood of wear and therefore increase the life of the entire system.

The repair is conventionally divided into several stages: preparation, dismantling of the pump, preliminary inspection, replacement of parts and / or elimination of damage, reassembly and installation.

To carry out repairs you will need: tools; rags; comfortable, spacious and clean place. Of the tools you will need:

keys and heads;
circlip puller;
a large syringe and a container for pumping liquid from the tank;
fine sandpaper P1000 / 1500/2000, file.

For repair you will need: a repair kit from a car dealer, or to replace it with washers, a gasket, O-rings and an oil seal. A suitable working bearing can also come in handy if that's the case.

First you need to dismantle the power steering pump. Then disassemble and inspect each component of the unit for damage, and then repair them. If the malfunction cannot be corrected, then from the next paragraph you will learn how to replace the pump by dismantling it and installing a new one.

Disconnecting the power steering pump and disassembling it is a painstaking process, so the first thing to do is to take more time for this process and stock up on nerves.

List of actions for direct dismantling:

We drain all the liquid, armed with a syringe and a container.
Disconnect the hose from the tank to the pump.
Unscrew the tensioner locking nut completely and remove the belt.
Disconnect the high pressure hose.
We remove the pump and clean it from dirt with water and a rag.
We put it on a pre-prepared clean place.

This completes the process of removing the pump from the power steering system and you can proceed to the stage of its disassembly and inspection.

Remove the bearing circlip with a puller.
Unscrew the fixing screws from the rear cover.
Remove it by prying it with a small screwdriver, but so that the rotor blades do not fall out. To fully control the process, it is necessary to remember the sequence of disassembly. This can be done using a camera or you can define a separate place for each part with a note in which order the parts were removed.
Remove the blades separately.
Pull out the plate and the parts underneath.
Knock out the shaft carefully.
Press out the bearing.

This is the third stage in which you need to determine where and what happened to the pump. To do this, you should:

clean all parts with a rag and carefully examine each;
eliminate all defects and roughness;
change the repair kit if the old one has become unusable;
do the same with the bearing, if it is in it.

If you notice burrs and roughness that appear as a result of wear, we remove them with sandpaper. Polishing allows you to remove gaps between parts and restore tightness. It is also used as a preventative measure to keep the pump clean and in working order.

Special attention should be paid to the rotor and polish it properly if there are burrs... It is problematic to do this, since you need good skill. Here, in addition to sandpaper, a small screwdriver will help, wrapping a sheet of sandpaper around which, you can get into the “most inaccessible places”.

Summing up all that has been said, after disassembly, repairs are carried out in several ways, depending on the breakdown. These are: bearing replacement; replacement of a repair kit; removal of burrs, roughness and unevenness; complete cleaning of the pump from wear and tear elements.

The assembly and installation of the pump in the car is carried out in the reverse order. When the installation process is complete, use the information from the last paragraph, and you will not have to repeat the procedure described in this article for a very long time.

Do not forget that repairing the power steering pump with your own hands can lead to additional damage. Therefore, carrying out this procedure, you need to do everything with the utmost care so as not to aggravate and not completely break the pump.

In conclusion, it is necessary to touch upon the topic of prevention. To reduce the risk of power steering malfunctions, simple rules should be followed:

use only the liquid recommended by the manufacturer;
monitor cleanliness - do not allow debris to enter the tank;
timely change the fluid and monitor its level.

This will ensure stable operation of both the pump and the entire hydraulic booster system.

Hydraulic power steering reduces the amount of effort required to steer the vehicle's wheels, which improves comfort and reduces driver fatigue. The inventor of the power steering is the American Francis Davis, who received a patent for his invention in 1925, and in 1950 the power steering was first installed on a serial Cadillac. The first power steering in the USSR began to be installed on the MAZ trucks, after which they appeared on the GAZ-66 and UAZ. Today, hydraulic power steering is installed in almost any passenger car.The development of technology does not stand still: the world famous Mercedes cars are equipped with a hydro-electric amplifier, and Opel has gone even further and installs an all-electric amplifier on its cars.

The photo shows the power steering, which increases driving comfort for the driver.

Power steering is a relatively simple and unpretentious mechanism in operation, which consists of:

a hydraulic pump, the main task of which is to pump oil and create operating pressure in the system
distributor, which is responsible for directing the oil to the desired chamber
torsion bar, which, by twisting in the right direction, supplies fluid to the distributor
a hydraulic cylinder responsible for converting the energy of fluid pressure into the translational movement of the piston. It is this unit that directly pushes the special rods, which help the driver to turn the steering wheel.

Like any machine unit, the power steering elements are subject to wear and tear and require both periodic maintenance and repair. The distributor, torsion bar and hydraulic cylinder are quite reliable parts and rarely fail, often amplifier malfunctions occur due to oil leakage as a result of mechanical damage to a plastic tank or oil pipes made of copper or aluminum. One of the most frequent breakdowns of the power steering is the failure of the pump: it is he who is subject to the greatest loads during the operation of the amplifier. It can fail as a result of untimely replacement of the amplifier fluid, which loses its properties during operation due to the appearance of impurities of metal shavings. Power steering assembly malfunctions are common as a result of vehicle operation with low power steering oil levels.

Video tutorial on what to do if the power steering pump howls

At different times, rotary, vane and piston pumps were installed on the machines, each of these designs has its own advantages and disadvantages. The rotary one has a high efficiency, but such designs have a very low resource, the piston one turned out to be expensive and quite whimsical in maintenance, therefore, it was the lamellar one that was most widespread.

The main pump malfunctions include:

leakage of working fluid through seal elements or glands;
noise and vibration as a result of bearing destruction;
decrease in discharge pressure.

Eliminating any of these faults will require removing the power steering from the vehicle. Do-it-yourself power steering pump repair is a rather difficult task, but it is quite a feasible task if you have the necessary tools and locksmith skills. Usually, there are no difficulties, we recommend using the vehicle's operating instructions, as well as carefully writing down or photographing the sequence of the removal and disassembly process in order to avoid possible problems during its assembly. It is easier to remove the power steering from a car in which there is a lot of free space in the engine compartment, for example, a GAZelle, but to remove the power steering from an Audi 100 or Chevrolet Lanos car, especially with a 1.5-liter engine, considerable skill is required. In any case, after removal, the pump must be thoroughly flushed from external contamination, check the condition of the housing and make sure there are no cracks on it.

If the fluid level in the power steering reservoir drops, this is a sign of a leak.

The power steering system is hermetically sealed, a decrease in the fluid level in the power steering reservoir necessarily indicates a leak. First you need to find the place from which the fluid is leaking. Very often, such a place is the elements of the pipe connection, a crack in a plastic oil tank. The most common place for fluid leaks is the power steering pump oil seal or its seals.Repairing such a malfunction will take a little time; to eliminate it, it is necessary to disassemble the pump and replace the worn-out seals and oil seals. It is worth paying attention to the condition of the shaft in the place where the oil seal is installed. If grooves or pits appear on it, then the gland will not fit snugly and leakage may reoccur. In this case, it is necessary to polish the shaft, but there are times when the wear is too great and it is not possible to achieve a tight seal of the oil seal, then installing an oil seal with a smaller inner diameter or replacing the shaft with a new one can help. In large cities, such as Moscow or St. Petersburg, there will be no problems with buying it, but in the provinces, the shaft will have to wait from several days to weeks, it is also worth considering the rather large price of this part from sellers.

Noise in the booster system can be caused by wear on the shaft bearings. If noise appears, it is necessary to eliminate it as quickly as possible, otherwise the shaft bearing may completely collapse, which will cause it to skew, which in turn can cause severe damage to the housing. Very often, such a malfunction occurs due to excessive tension on the hydraulic pump belt, which as a result causes excessive stress in the bearings and leads to their destruction. You can also replace bearings yourself. First, you need to remove the worn bearings, then press two new ones into the pump housing and cover, then put them on the shaft. When replacing bearings, be sure to replace the oil seals and gaskets.

The reasons for the decrease in pressure may be the wear of the ellipse of the inner cylinder or the rotor blades themselves, however, the resource of these parts is hundreds of thousands of kilometers, and sometimes they do not have to be changed at all during the entire operation period, as, for example, for Ford Fusion or Ford Focus 2. Much more A common cause of pressure loss is sharp burrs on the rotor that prevent the blades from working properly. As a result, they may not fully come out of their grooves or they may even jam, which will cause a decrease in pressure. The repair in this case is quite simple - it is necessary to process the sharp edges of the rotor at the point of attachment of the blades with sandpaper or a grindstone.

From car owners Daewoo Nexia (Daewoo Nexia) and Daewoo Lanos (Daewoo Lanos) With Power steeringohm quite often one hears questions - Do I need to change the oil in the power steering at all?, When it is necessary to change the fluid in the power steering ( power steering )?, What kind of oil should be poured into the power steering on Nexia and Lanos cars?, How to replace fluid in power steering? And if there are questions, then they must be answered. Let's start in order. We can say with 100% certainty that the power steering fluid needs to be changed! Why not? It is necessary to change the oil in the engine and gearbox, antifreeze and brake fluid are also necessary. And there is no power steering? Is she there, eternal? Of course not. Here are several reasons that may serve as a reason for replacement - "tight steering wheel", the noise of the power steering pump, the fluid level in the tank is below the minimum mark (in this case, it is better to change than to add and mix) and finally scheduled maintenance. Regarding the last point, there are no precise recommendations, unfortunately. Not a single book on car repair for Daewoo Nexia and Lanos contains exact figures for the mileage of the car when it is reached, which should be replaced with the fluid in the power steering.

So, here the choice is given to the owner of the car. Of course, I can give a recommendation on my own - change the fluid upon reaching 50,000 - 60,000 km (this is a rather large mileage). But immediately, there will be people who will shout at interruption that they already have 100,000 and more on the speedometer, and they have everything ok with the liquid and they are not going to change it ... I will not argue and I will repeat, the decision is yours.

Now for the choice of oil ... There are two options - DEXRON 2 and DEXRON 3... What is the difference, I cannot say. Poured into Power steering Daewoo Nexia (Daewoo Nexia) and Daewoo Lanos (Daewoo Lanos) dextron 2 and dextron 3. I did not notice the difference. You can stop at the branded GM DEXRON 2 (just he is in the photo). Required fluid volume - 1 liter .

By the tool that will come in handy when changing the fluid in the power steering - pliers, socket wrench for "10", a large syringe or a pear, a plastic bottle with a volume of 1 liter and of course, a few rags.

Now about the main thing - changing the fluid (oil) in the power steering (power steering) on Daewoo Nexia (Daewoo Nexia) and Daewoo Lanos (Daewoo Lanos) cars:

1. We hang out the front axle of the car with jacks.

2. With a large syringe or a medical pear, select the old liquid from the tank (photo 1).

3. Unscrew the reservoir with the key on "10" (photo 2).

4. Using pliers, squeeze and release the clamps (photo 3), remove the hoses and take out the tank (you can put a rag under the tank beforehand, since oil leakage cannot be avoided). The tank can be rinsed with clean gasoline. In Lanos tanks there is a net (we look at how dirty it is) and a check valve (photo 4, before washing the tank we take it out and try not to lose it. After washing, we put it back). We wipe and dry the tank.

5. Now it is necessary to remove the remaining fluid from the hoses. To do this, we substitute a container under the small hose (return), direct the hose into it (photo 5) and turn the steering wheel, first to the extreme left, and then to the right position.

6. Put the tank back in place and put on the hoses. Pour new fluid into the tank at the "Max" mark. And we turn the steering wheel to the left and right sides until it stops. Checking the liquid level. After that, for the final pumping of the system, we start the car and turn the steering wheel again. We set the steering wheel to the straight-ahead position and turn off the car. Once again we check the liquid level in the tank, top up if necessary.

Automotive steering rack has been used in automobile construction for a long time. Without this detail, transport control becomes impossible. With the development of technical progress, mechanical steering racks began to be replaced by hydraulic and electrical ones. The steering rack, which is part of the Daewoo Nexia mechanism, is used in conjunction with power steering (power steering). Such a mechanism allows to reduce the mechanical costs of the driver's forces while driving.

Every Daewoo Nexia car owner should know how the steering rack structure works.
Important!In the USSR, the power steering was first used in 1950 for the MAZ-525 dump truck.

The rail consists of the following parts:

The power steering pump is directly connected to the engine and is driven by a gear change. A high pressure pump draws hydraulic fluid into the distributor. The valve is part of the crankcase mechanism (housing).

In the stationary mode of the car, no forces act on the Nexia steering rack, while the distributor channels are blocked, the oil remains in the reservoir. If the car is set in motion and turns into turns, that is, turn the steering wheel, there is resistance from the wheels. At the same time, the torsion bar, which is part of the distributor, begins to twist.

During this time, hydraulic fluid is supplied from the distributor to the steering rack. Then the oil falls in the right direction and presses on the rail.

Important! Every 50-60 thousand km of run it is necessary to change the hydraulic fluid in the steering gear system.

This mechanism is almost always in a dynamic state, so it is necessary to regularly monitor the condition of oil seals, bushings, bearings, etc. To do this, you do not need to disassemble half of the car, it is enough to check if oil is flowing from the front of the car.

There can be many signs of a defective steering gear. But most importantly, if you hear a knock from under the front axle, it's time to go to the auto repair shop.

Here are all the signs that a gearbox needs repair:

When turning the car, you have to turn the steering wheel strongly.
At high speed, he begins to throw the steering wheel and skid to the sides.
When driving on uneven terrain, a knock and recoil starts at the steering wheel when it is in its central position, while cornering the recoil disappears.
General breakdown of the hydraulic fluid in the system.
After entering the turn, the wheels of the car return poorly to their original position.
When driving at high speeds, the steering wheel begins to vibrate and rotate spontaneously.
Oil leakage from the power steering system, which indicates damage to oil seals, anthers, Teflon rings, etc.

If at least one of the above points can be attributed to your car, then you need to do an urgent inspection of the car. After all, if you do not prevent damage, the steering rack of your Daewoo Nexia can become completely faulty at high speed, and this entails sad consequences.

The main reason for the deterioration of steering racks in our country is low-quality roads. The service life of your gearbox is directly proportional to the quality of the roads. If you do not slow down in front of the pits or go around them, over time you will feel the characteristic knock of the front axle, which will be the first signal of a malfunction.

Did you know? The steering wheel first appeared in France in 1894.

Winter drift is considered to be another option for gearbox breakage. When the wheels are turned out and at the same time do not rotate, they give a tremendous load on the crankcase and shaft. At the same time, there is a risk of damage to the oil seals and anthers, as a result, dirt begins to get into the system, which over time destroys the entire mechanism. It is also worth remembering to regularly change the hydraulic fluid in the system.

According to statistics, the most frequent repairs of the Daewoo Nexia steering wheel are due to wear on the slide, seals and stem. Often times, bearing crashes are caused by knocking in bearings, which are bumped on a regular basis. An imbalance in the bearings impairs the correct functioning of the gearbox.

Diagnostics of the Nexia Reiki must be carried out in three stages:

Initial inspection of the mechanism's performance on the car.
Diagnostics after removing the mechanism, checking the backlash, integrity of oil seals, bushings and bearings.
Detailed inspection of all components of the steering gear.

At the first stage, we need to make sure which mechanism failed. Are there any breakdowns in the auxiliary mechanisms. Check the integrity of the system and the presence of hydraulic fluid. We also check the backlash on the bushings.

Important! In winter, before driving, you need to turn the steering wheel in different directions several times, so the risk of damage to the steering mechanism is reduced.

At the second stage, the entire mechanism must be clamped in a vice. Next, check the output along the teeth in the worm pair. You should definitely make sure that the apples of the steering rods do not rust. All this is done in order to understand whether a complete replacement of the rail is needed or only a part of its mechanism.

In the third stage, each element of the mechanism is checked separately. After a detailed check, a conclusion is made about possible malfunctions in the mechanism.

If the backlash is not strong, then perhaps the repair of the rail on your Daewoo Nexia will not be needed. The backlash can be eliminated by the first tightening of the gearbox.

But it is worth noting that the backlash does not have to disappear without a trace. The fact is that without opening we cannot find out the degree of wear of gears, torsion teeth, etc.

Did you know? The first power steering patent was issued in Great Britain in 1902. Frederick Lanchester became its rightful owner.

Still, it is worth tightening the rail (you need the help of a friend), and if the tightening does not give the desired result, then you should contact a car service.

To carry out this manipulation, you must adhere to this plan:

The main task is to tighten the adjusting screw, which is located in the end cover of the steering gear.
To carry out this manipulation, you will need a garage pit, and if it is not there, then use a jack.
Before operating the jack, the wheels of the machine must be set in a straight position.
The steering wheel play can be measured with a play meter. The indicator should not exceed 10 ° (this is what GOST says).
The tightening should be done slowly. After scrolling a little, you need to check if the play on the steering wheel has disappeared.
Check the car in dynamics, if at speed you feel heaviness while cornering, you will need to loosen the adjusting screw.

If the backlash and knocking have disappeared, the steering wheel does not vibrate at speed, and you do not have to exert effort when cornering, then the problem is considered solved. Otherwise, you need to contact a car repair shop.

Replacing the Nexia steering rack may only be required after a complete inspection of the mechanism by professionals. In the best case, only repair or replacement of individual parts of the mechanism may be required.

Important! Using power steering at high speeds requires minimal effort to turn the steering wheel, and at low speeds, more effort is required.

Repair of the steering rack in the workshop is done in this way:

Did you know? Telescopic steering wheel adjustment first appeared on Ford cars in 1955.

All of the above steps for replacing the Nexia rail should be carried out only with experience and special equipment. Otherwise, it is better to go to a workshop.

The new Nexia steering rack with power steering has a decent price, so motorists recommend following some tips to avoid damage to the mechanism.

Helpful hints:

Monitor the condition of the anthers and oil seals. Damaging them is the first step to breaking the entire mechanism.
When twisting the steering wheel to its extreme position, do not leave it there for more than 5 seconds. Do not run the engine at high revs while cranking the steering wheel fully. This leads to wear of the power steering, steering gear, etc.
It is worth abandoning the winter "drift" if you do not want to constantly go to the auto repair shop.
In the workshop, try to control the entire process of disassembling and assembling the mechanism. Mechanics often forget to tighten any nuts. In addition, you need to ensure that the work is done with clean hands, as dirt can get into the system, which will lead to problems within a few days after the repair.

If you adhere to these tips, then the longest possible operation of the mechanism without repair will be ensured.
