What, what, what, what are our pumps made of))))
I don’t know how on 40vkah. but at 60,70,80,90 since 2000 there are ZF pumps with an external reservoir.

in general, people are often contacted. with problems of hum, leakage.
Fortunately, friends from the Volvo OD helped, they got me a test subject. pump. deadly.
from then he got to me on the operating table.
I do not want to draw premature conclusions about the possibility or impossibility of serial recovery of this unit yet, but ahead of the events I will say that the design shocked me a little.

so that there are fewer unfounded statements. further photo in the process of disassembly.

external view of the removed pump:

further unscrewing the 4 bolts of the body:

remove the top (whether the bottom is how to look) cover:

Well, under the lid, the intestines. complex design with different channels, variable nozzles. most of aluminum and alloy:

under the cover, rotor with “floating” steel blades. :

rotor with blades removed:

well, the general plan. dismantled everything (almost):

what in the end:
surprised - a completely metal rotor. blades. logically, such a structure is designed for a century of work.
puzzled - there is not a single bearing in the design.
the pulley shaft rotates in an aluminum casing, into which steel bushings 0.3mm thick are pressed. structurally, a lubricant is forcibly supplied to the friction zone (aka gur fluid).

from what I saw I can tell. a very complex hydraulic system that requires a timely change of the working fluid. the quality of the working fluid is extremely important. since it not only transmits hydraulic power, but is also the only lubricating element in the system.
I will inform you about the possibility of pressing out the bushings and the oil seal later, since this is a non-trivial task. we will see. so as not to screw up the system.

in fact this pump.
there is wear on the bushings. but as stated above. from dirty oil, which became an abrasive.
several tubules were completely coked up. the upper seal is burnt from overheating (this can be seen in the photo).
so the advice is to change the liquid as often as possible (at least once every 30 thousand), and not to save on oil (you can drink cheap beer, but cheap oil is fraught with danger.).

although a second-hand node costs $ 140-170 in Minsk. if someone thinks that it is easier to replace an organ than to keep an eye on it. flag in hand.
but now you don’t say you didn’t know. I'm not guilty.

Novel - ATF has many varieties. The Americans, if I'm not mistaken. there is already a VI type. Europe is more conservative.

Didn't notice about the replacement right away. SOME automatic transmissions also write that for the entire service life of the car. and the declared resource 120,000 km

My oil change ended up with vibrations when turning the steering wheel, a feeling of sticking, the steering wheel began to turn harder. This is after changing the green slurry to Mobile ATF320 with flushing. After a day train, I went and bought a green one and changed it again. Now it is better, but, as it seems to me, worse than it was before the replacement. Even though the color was with signs of a clear pump depletion.

At one time the pump on my Mazda started to fail, and “dead zones” appeared. An unforgettable feeling when you lightly turn the steering wheel in a turn, and it suddenly stops turning, and you have to pile on with your other hand. That still adrenaline! Posed with a belt and passed.
And there was also a case, on the previous car, also a Mazda, when the steering wheel was turned, the revolutions rose. When you enter a turn, you release the gas pedal, and due to the steering wheel twisting, the speed is not reduced. Oh yes, the Japanese.

A counter question: what method is used to drain the liquid from the tank, and how is the system flushed?

Flushing could be harmful. One person with flushing finally got the pump jammed - the inside was ripped off for release. Before that, he worked perfectly. I wanted to do the best.
I don’t use washes. The risk of them ruining the unit 50X50. This also applies to fuel equipment.

Volvo's power steering system is specially designed for increased comfort and reliability of vehicle operation. The power steering unit consists of a main operating unit (steering rack), a unit that ensures the operation of the main unit (power steering pump), a reservoir for a working fluid (expansion tank), a hydraulic fluid cooling system (spiral or radiator) and a system of connecting pipelines and hoses.

The content of the article:

Signs of a breakdown of the power steering pump may be noise or whistle arising during operation under load and during idle operation. Problems with turning the steering wheel in place or while driving may be related to the bypass valve.

Direct evidence of a pump breakdown is jammed pump pulley... Volvo power steering pump creates high pressure> 150 kg / cu. cm, for functionality which requires oil that provides sufficient friction protection and good heat dissipation.

For the normal functionality of the pump, as well as the power steering system as a whole, it is necessary to change the oil, constantly monitor its condition, and change only to a liquid that meets the requirements, do not allow the oil level in the tank to drop below the minimum mark, because this can lead to air entering the system and lead to overheating of the pump.

If the oil level in the reservoir is constantly decreasing, you need to inspect the power steering system for leaks, check the integrity and tightness of the pipelines, the power steering pump itself, leaks from the steering rack.

On most Volvo S60, S90, XC90 models, a power steering pump with an external reservoir is installed. The pump is designed in such a way that no bearings or seals are usedand the pump blades and bushings are made of steel.

With high-quality service, timely replacement of the hydraulic fluid in the power steering, the pump will serve reliably throughout the entire service life guaranteed by the manufacturer.

If necessary, the removal, repair or replacement of the Volvo power steering pump can be carried out independently.

1. It is necessary to raise the front axle of the vehicle to provide access to the power steering pump from the bottom side.
2. Remove the power steering fluid from the expansion tank by suction with a syringe.
3. To remove oil from the power steering system, place the return line hose, which fits to the upper connection of the tank, into the container, and turn the steering wheel to the right and left several times.
4. Loosen the drive belt tension adjustment screw. Loosen the pump mounting stud and the nut securing the belt tensioner position.Use WD-40 to ease the process.
5. Remove the drive belt.
6. Disconnect the supply hose from the Volvo S60 power steering pump.
7. Disconnect the high pressure line. To do this, you need to use 2 keys (22 and 17): fixing the position of the union with a 22 key, turn it off with a 17 mm key.
8. Remove the pump mounting pin and retaining bolt.
9. Remove the pump.
10. Installation is in the reverse order.
11. After installing and filling with hydraulic fluid, make several turns of the steering wheel to remove air from the power steering.

If there is heavy steering syndrome, then, perhaps, this breakdown refers to the bypass valve of the power steering pump.

The reasons for this breakdown: contaminated power steering fluid, the fluid level in the reservoir is below the minimum, a change in the oil composition due to overheating, increased loads on the pump (long-term holding in the extreme positions of the steering wheel).

Repair of this breakdown consists in complete disassembly of the pump and thoroughly cleaning and flushing all pump passages.

Be careful, the pump has technical clearances up to hundredths of a mm!

If oil leaks from under the pulley or shaft play is detected, repairs can be done by hand.

1. It is necessary to thoroughly clean the removed pump from dirt. It is very important to be clean. Pump operation is based on tightness, any inadvertent clearance will affect the functionality of the pump.
2. Remove the rear housing cover. To do this, unscrew the 4 screws.
3. Remove the adjusting ring.
4. Remove the rotor stopper.
5. Pull the rotor out carefully to keep all blades in place.
6. Remove the shaft with the pulley.
7. Remove the old bushing from the pump housing, using a homemade puller.
8. Next, it is necessary to bore the body to the required diameter with a difference of 2-3 hundredths of a mm, about 17.4 mm, choosing the sleeve according to the shaft diameter. Experience shows that there is practically no shaft wear. Press-fit the sleeve into the pump housing. Inner diameter 15 mm.
9. The pulley shaft should be turning with a slight tension.
10. The pump is assembled upside-down.
11. Be sure to change the power steering fluid.
12. Carry out operations to extract air from the power steering system.

A similar problem is XC90 3.2
The power steering began to turn off periodically, changed the power steering fluid, flushed the tank. The color and consistency of the liquid is not good, to put it mildly.
As I understand it in the future, the replacement of the power steering pump? Or is there a chance to save?

The total volume of the washed and replaced fluid was 2.5 liters, after a couple of hundred km, I think to change it again to wash out all the guano.

The power steering fluid in the Volvo XC90 is an oil that transfers resistance from the power steering pump to the hydraulic cylinder, and also lubricates all friction pairs. The oil is circulated through the hoses connecting the power steering units, including the Volvo XC90 power steering plastic expansion tank, which has MIN and MAX marks to determine the level.

The power steering system itself is the Volvo XC90 hydraulic system, part of the steering mechanism to make it easier to turn the steering wheel and set the trajectory. If the power steering refuses, it is possible to drive the car, but the steering wheel will be difficult to turn, it will become heavy.

The power steering fluid level in the Volvo XC90 can be determined by the marks on the power steering plastic expansion tank. During operation, the Volvo XC90 power steering fluid can flow in various places, most often through hoses. As a result, the power steering oil level will drop.

Driving without fluid in the Volvo XC90 power steering puts the power steering pump at risk of damage, which costs a lot of money as it runs dry. As a result, he will receive serious damage and fail. The power steering pump in the Volvo XC90 starts working as soon as you start the car. If your Volvo XC90 is left without oil in the power steering system, then the best solution would be to call a tow truck.

Intensive use of the Volvo XC90 makes the power steering oil color darker over time, often with a burning smell. This is a reason to think about replacing it. Overheating of the oil often occurs when the steering wheel is fixed for a long time in the extreme position, until it boils, the pressure in this case is maximum. You should also not leave the car when parking for a long time with the steering wheel turned all the way.

A quick preventive maintenance and inspection of the Volvo XC90 power steering includes: control of the power steering oil level and its quality in the power steering expansion tank, checking the tension of the drive belt on the power steering pump Volvo XC90, assessing the condition of the hoses - cracks, smudges, fogging, as well as searching for leaks at the joints of the power steering elements.

There are two ways to change the fluid in the Volvo XC90 power steering:

• partial replacement of power steering fluid Volvo XC90.
• complete replacement of power steering fluid Volvo XC90.

For a partial replacement of the power steering oil, you will need a syringe (with a tube) and the oil itself, so much that at the end of the work it ceases to be dark.

Partial power steering fluid change in Volvo XC90:

1. We unscrew the cover of the power steering expansion tank Volvo XC90.
2. With a syringe with a tube, we completely pump out the liquid from the power steering tank.
3. Fill the tank with new liquid, up to the MAX level.
4. We start the engine and turn the steering wheel left and right to the extreme position.
5. We turn off the engine and repeat point # 1 again until we get the desired result - light oil.

The next method for changing the power steering oil in the Volvo XC90 will allow you to achieve almost 100% replacement.

Complete replacement of power steering fluid in Volvo XC90:

Drive onto an overpass, or jack up the car so as to hang the front car wheels of the Volvo XC90, in order to be able to easily rotate them on an uncranked engine.

The first real SUV produced by Volvo entered the ranks of crossovers quickly and took its due place in the short ones. Car enthusiasts in Europe liked the car almost immediately. The presence of excellent off-road qualities, all-wheel drive, beautiful design and powerful engines quickly made the Volvo xc90 a leader in sales. But the leaders sometimes break down and then it becomes necessary to repair the power steering Volvo xc90

Even such a reliable unit as the Volvo xc90 power steering can break down if you do not take proper care of it and allow the following violations:

• do not control the tension of the pump drive belt;
• do not replace a worn drive belt in time;
• do not monitor the liquid level in the filling tank and allow it to fall;
• drive the car at low idle speed;
• do not replace the tank filter in time;
• allow the presence of low operating pressure in the power steering pump;
• do not exclude the ingress of air into the hydraulic booster;
• use a hydraulic booster with a faulty pump;
• do not monitor the condition of the tires;
• allow wear of steering parts;
• do not timely replace damaged hoses (high and low pressure).

The appearance of the following symptoms will tell you that not everything is in order with your power steering:

• Recoil (kickback) on the steering wheel.
• The steering wheel is turned with great effort.
• Turning the steering wheel quickly requires a lot of effort.
• The steering wheel turns harder one way than the other.
• When the steering wheel is in the middle position, a lot of force is required.
• Vibration occurs in the steering wheel.
• When the power steering is working, noise is heard.
• Steering is not clear.

Not every car owner can determine the breakdown by eye and contact the service station in a timely manner. Depending on the problem, delaying the repair can result in both additional waste and a threat to the life of the driver and passengers. That is why we will discuss the repair of the Volvo xc90 steering rack and everything related to this mechanism, as well as help determine the cause of the breakdown and give some advice.

First, let's figure out what the steering rack is, what functions it performs and where it is located in the car.

The steering rack in the Volvo xc90 is a linkage mechanism between the steering wheel and the steering wheel components. That is, the steering rack is the link between the steering wheel, which is located in the car, and the wheels. This mechanism makes the wheels turn in the direction in which you turn the steering wheel.

If you have a new car, then the rack will be equipped with additional hydraulic or electric boosters, which facilitate steering movements and, thus, allow you to turn in one direction or another with less effort.

How does it all work? You turn the steering wheel, after which your efforts are transmitted to the shaft and mounted gear. The gear transmits rotational movements to the rail. The mechanism deviates in the right direction, and the hydraulic booster comes into play. Oil is pumped through the system into the desired cavity of the hydraulic booster, thereby simplifying the movement of the rack.

The steering rack mechanism itself has many component parts, so even experienced motorists do not undertake the repair of this control element. For this reason, any breakdown associated with the described component is eliminated exclusively by a service center.

Did you know? By 2040, 50% of new cars are projected to be hybrid.

Before calculating the costs of repairing the rail and sinning on broken roads, you need to understand whether that mechanism has become unusable, or something else has broken down.

Malfunction symptoms:

• reduction of liquid in the expansion tank (it is worth paying attention to the seals of the seal);
• knocks or squeaks under the steering wheel (wear of the teeth or ball joint);
• the steering wheel turns with difficulty (shaft deformation);
• strong vibration and rebound of the steering wheel on an uneven road (tips are damaged);
• presence of oil stains under the car (problem with steering hoses).

Important! A breakdown of the steering rack on the xc90 can lead to tragic consequences, therefore, regularly check its serviceability, and in case of malfunctions, immediately go to the service station.

The reason for the frequent repair of the steering rack on the volvo xc90 is not always a factory defect. Our roads and climate are often decisive factors that shorten the service life of a machine.

Main reasons:

• Broken roads. Every deep hole that you hit at high speed leads to rapid wear and damage to the vehicle's control system. Therefore, try to reduce your speed to a minimum if you see serious unevenness in the asphalt pavement.
• Careless driving. If you like to drive at high speed, skidding around corners, then be prepared to frequently replace the rack or other components that work with it.
• Sharp acceleration with the steering wheel turned to the left or right. Just as negatively affect the mechanism, as the two previous factors.
• Check in at the curb. This habit breaks the control system as quickly as pits on the roads.
  

All of the above factors seriously affect the wear of the rail, so if something from the list cannot be eliminated, then try to drive more carefully, taking care of your car.

Repair of the xc90 steering rack always begins with a diagnosis, which takes place in 3 stages:

1. Initial inspection. Carried out on a car without removing the mechanism.
2. Secondary inspection. Diagnostics of the removed unit is carried out.
3. Tertiary inspection. Disassembly and detailed inspection of all parts.

Such stepwise diagnostics allows you to figure out whether the breakdown is really related to the rail, or problems in the chassis of the car.

First stage. The hydraulic system, the level and color of the fluid in the tank are checked. Examine the backlash in the cross and the state of the worm pair. Next, the tie rods and tips are examined.

Second phase. If at the first stage everything speaks about the breakage of the rail, then it is removed and a detailed examination is carried out. The unit is checked for cracks and rust, deformations. At this point, we can draw conclusions about whether it is worth repairing the rail or it is easier to buy a new one.

The third stage involves a detailed analysis and repair of the unit. If during the preliminary inspection it is difficult to say whether it is worth repairing or it is better to throw it away, then the mechanism is disassembled, separating all parts, and carefully inspected.

Then the specialist makes a verdict, and you can make a decision based on the price of repairing or buying a new unit.

Did you know? Volvo has equipped its cars of the future with a system that recognizes road signs indicating pavement conditions. Upon seeing the "Dirt Road" sign, the car will not only change the settings of its systems, but will also warn the driver to slow down.

First, let's talk about when the unit is adjusted, and what this procedure will give us.

Important! Only a working mechanism lends itself to adjustment without deformations, cracks and other serious violations.If the service station made it clear to you that the rail is faulty, the adjustment will give nothing.

It is necessary to adjust the unit if there are problems with a tight turn of the steering wheel. It is important to understand that in any other case, the adjustment will be useless.

So, let's consider in order what and for what needs to be done in order to repair the unit:

1. We set the front wheels straight and connect the jack for lifting the body.
2. We measure the backlash of the steering wheel with a special device (according to GOST, the deviation should be up to 10 degrees).
3. We tighten the adjusting screw, which is located in the end cap.
4. We carry out the entire procedure slowly, without jerking or abrupt movements. During the adjustment, we constantly check the steering wheel travel and play (do not forget about the knock in the column).
5. If after tightening there is a feeling of heaviness in the steering wheel, slightly loosen the screw.

This completes the adjustment procedure. It is worth remembering that if after the above the problem has not gone away, then you need to contact a specialist - further braces will not work. Until the complete disassembly of the unit, you cannot know what the problem is, so do not put the control system to the test again.

The unit is dismantled from the car and installed in a vice. Further, a complete analysis of parts is carried out. All the components of the mechanism are unscrewed, the bolts are removed, the springs are pulled out.

Next, the main structure (cast part) is washed, removing all dirt and grease. After that, they conduct a detailed inspection, find the problem part and either make a replacement, or inform the owner about the cost of replacing the part and the feasibility of repairing it.

During the process of repair and further collection, all parts are lubricated to increase the service life after repair.

Important! During the repair process, worn out gaskets and seals can be replaced.

You can clearly see the whole process of work in this video. The main stages of disassembly and assembly of the unit are shown.

Many foreign manufacturers write that the components of the control system have a service life of about 13-15 years. However, it should be understood that such durability must be ensured by certain efforts, which we will talk about.

1. The quality and cost of the oil is the key to the long operation of the mechanism. Not only should you use a good quality oil, but you should also regularly check its level, color and consistency.
2. Regular checks. Try not to forget about the service station when everything is in order with the car. Just as a person needs to go to the hospital for an examination in order to prevent the onset of diseases, a car needs regular diagnostics. So you will not only solve the problem in time, but also reduce costs.
3. Do not twist the steering wheel all the way. By doing this, you disrupt the normal operation of the control system.
4. Constantly check the protective boots for leaks: replacing them will be cheaper than repairing the rail or system components.
5. When planning your route, try to choose more or less high-quality roads, as saving time can entail serious expenses.

This concludes the discussion of fixing and adjusting the steering rack. Always remember that the service life is not determined by the manufacturer, but only by you and your actions on the road.

This device significantly increases the machine's controllability and maneuverability, which has a positive effect on the overall driving safety. Autotech center Volvo Zelenograd will perform repair of power steering Volvo any model with high quality and in the shortest possible time.

Employees of our Volvo Zelenograd Technical Center are ready to repair Volvo cars of any complexity and, which is not unimportant, in accordance with the technology provided by the manufacturer.

For repairs, we use original spare parts and technical fluids purchased from trusted suppliers, which excludes the possibility of installing counterfeit parts, and we are also ready to offer our customers non-original spare parts from well-known world manufacturers,which are of a fairly high quality at a significantly lower price.

We carry out such works as:

• engine and gearbox repair
• replacement of suspension, transmission, steering and brake system elements,
• diagnostics of all electronic systems of the car,
• diagnostics and repair of the air conditioning system,
• cleaning the external surfaces of radiators with dismantling the entire package,
• replacement of technical fluids.

The hydraulic booster is an integral part of the steering column of a car and, in turn, consists of:

• A circulation pump designed to pump the working fluid in the system and maintain the working pressure;
• A distributor with a torsion bar, which monitors the force on the steering column and directs the fluid to the desired cavity of the hydraulic cylinder;
• Hydraulic cylinders with a piston, which are an actuator that transmits the force of fluid pressure through the rod and a system of levers to the wheels;
• Systems of hoses and pipelines connecting all elements of the power steering into a single whole.

[

Does your car feel extra heaviness when you turn the steering wheel? Do you feel unusual vibrations and hum? It's time to check the tension of the drive belt, as well as the level and condition of the oil in the system.

By the state of the working oil in the power steering system, one can judge the degree of wear of all rubbing parts of the mechanism. During operation, metal particles enter the oil and, being re-transported to places of increased friction, act as an abrasive and cause additional wear.

If you do not take any action, this will very quickly lead to failure and the need to carry out repair of the power steering pump Volvo... This power steering element is the most important part of the entire system and fails most often.

It is much easier and cheaper to change the oil on time - once every 50 thousand kilometers, as well as periodically inspect it for metal particles. To do this, it is enough to illuminate the oil in the expansion tank with a flashlight and the metal shavings will give reflections, the intensity of which can be used to judge the degree of wear of the mechanisms.

Automotive Technical Center Volvo Zelenograd conducts diagnostics of the power steering system, as well as repair of Volvo pumps - our masters specialize in the repair of cars of the Swedish concern and have studied their features.

In difficult cases, we will not recommend a repair, but replacement of the power steering pump for a new one - we always have the required stock in our warehouse.

In general, Volvo cars are quite reliable, and when performing regular maintenance, they serve their owners faithfully for a long time. However, a number of malfunctions are still characteristic of them. This:

• wheel bearing play or noise
• rupture of front suspension silent blocks
• Leaking cooling system radiators
• failure of the air conditioning compressor (for some engines)
• malfunction of the steering angle sensor
• knocking due to defective shock absorbers
• knock of rear springs (for XC90)
• burning of the fuel pump contacts (for diesel engines)
• fuel level sensor malfunction
• noise or complete jamming of the overrunning alternator clutch
• turning the connecting sleeve between the automatic transmission and the angular gear

The operation of the power steering pump is aimed at supplying fluid designed to create pressure in the steering system. Extreme driving style, violation of the tightness of control units, as well as mechanical damage and improper operation often become the reason for the failure of the power steering and related elements of the vehicle. Repair of Volvo power steering pumps allows you to restore the technical characteristics of the device, and provide a high level of safety for the driver, his passengers, and other road users.

You can independently determine the malfunction that has arisen with the power steering pump by the following characteristic features:

• during maneuvering, there are some difficulties with turning the steering wheel, which is associated with malfunctions of the bypass valve - an element that controls the flow and rate of supply of hydraulic fluid;
