DIY steering gear repair sable with power steering

In detail: do-it-yourself repair of a steering gear sable with a hydraulic booster from a real master for the site my.housecope.com.

Gazelle Sable. Power steering adjustment

The adjustment involves two steps: adjusting the screw thrust bearings and adjusting the gearing.

Adjusting the screw thrust bearings

In order to determine the need for adjustment, set the steering wheel to the middle position.

Disconnect the longitudinal steering rod from the bipod (see "Replacing the steering rods and their joints", p. 108).

... while constantly shaking the bipod, we control the backlash until it is completely eliminated.
We lock the adjusting nut with a beard, settling the sections of its collar into the grooves of the crankcase.

Gear adjustment

The gearing is adjusted only after the play in the propeller bearings has been eliminated.
On a mechanism installed in a vice.
... holding the input shaft with a 16 key.
... swing the bipod. The play should not be felt by the hand (exceed 0.3 mm at the end of the bipod).

Otherwise, remove the bipod from the shaft-sector. We treat the connection with a penetrating liquid.

Adjustment of the steering mechanism is needed when the vehicle is in low directional stability at high speed (the steering wheel does not seem to be felt at high speed).

This defect is associated with a violation of the adjustment of the thrust bearings of the screw, and in a pair of rack-piston - shaft-sector of the steering mechanism.

After adjustment, the force required to rotate the input shaft should not increase appreciably. During operation, you should constantly monitor the condition of the hoses, especially high pressure. If cracks, bumps or cuts occur, the hoses must be replaced. You should also check that there are no leaks of working fluid (oil) from under the hose clamps, steering gear covers or the power pump.

Video (click to play).

When the pressure in the system rises due to jamming of the bypass valve, technological plugs in the pump housing can be squeezed out, therefore, you should monitor the system and the quality of the filled working fluid, top it up, replace and replace the filter on time.

Do not hold the steering wheel in extreme positions for a long time. This could damage or even jam the booster pump.

A weak noise from the amplifier is not a malfunction.

We remove the steering gear without removing the bipod.

1. Clamp the mechanism in a vice with the fittings down and drain the remaining oil into the container, turning the mechanism shaft with a 17 key.

2. Pressing the spool shaft with your hand, we swing the bipod. If at the same time axial play of the shaft is felt, adjust the thrust bearings.

3. To do this, through a bit or a punch, we straighten the collar of the adjusting nut, which is nailed into the grooves of the crankcase.

4. With a special wrench, turn the nut clockwise until the gap is eliminated.

In this case, we control the torque of the shaft, which should be no more than 0.2 kgcm.

5. To do this, we measure the torque of the spool shaft with a dynamometer hooked onto a 17 key.

With a lever length equal to 200 mm, the force should not exceed 1.0 kgf.

6. Bend the collar of the nut into the groove with a beard

7. Wiggle the steering mechanism bipod by hand. If you feel a gap, adjust the gearing

To facilitate control of the Sable, the manufacturer installs a hydraulic booster. If you have difficulties in repairing Sobol power steering with your own hands, our video will tell you quick and effective ways to restore the power steering.

If the owner noticed that the gur pump does not work, further repair of the unit on Sobol should begin with determining the reasons for the failure. The main ones are described below, as well as recovery options.

Poor system strap tension. The solution to the problem is position adjustment or replacement.
Mechanical problems. In this case, the repair of power steering (GUR) Gazelle, UAZ, Sobol, Volga must begin with diagnosing the state of the components.
The steering wheel turns poorly. The reason for this can be either a low oil level in the system, or belt wear. You should also pay attention to the engine speed and the condition of the filter - it may be clogged.
The pump refused to run. To restore the power steering pump of a Sable car, you need to purchase a new repair kit and replace all seals / oil seals / other parts.
The presence of extraneous sounds and clicks. The reason is severe wear of the controls. To view the power steering repair manual, open the video on this page.
Absence of normal pressure of the working fluid. Practice shows that this is due to poor operation of the pump, or the presence of a leak in the system.
Wear or damage to tires. The only solution is to install a new kit. Riding on damaged tires is highly discouraged.

For further repair of the power steering pump quickly with your own hands, our video will always be useful. The wizard gives detailed explanations, and also shows the sequence of actions when repairing power steering on Sobol.

And what is the first thing to change?
I have it completely new, but only in '98 under number 222.
All this time I lay in the garage.
After reading reviews about fluid leaks from our precious domestic creations, I decided not to risk it, but to sort it out.
I contacted firms for this specialization, they announced 3 thousand I do not understand just for WHAT? -)
the oil seals need to be changed, this is understandable. I found two of them.
Does anyone have experience with bulkheads and what needs to be replaced for every fireman?

In fact, nothing complicated, but you need to find a suitable set of oil seals for your power steering. I usually change all the oil seals right away - the kit is only 200 - 300r. And then what to disassemble again.

I will try to describe the process later - there are pitfalls, there is simply no time now. wait a little, and maybe someone else will unsubscribe.

In general, it is real and even without a garage and adapt. I went through several times right on the street, but it is necessary that garbage and sand do not fly into the insides, the atoms will grab the surfaces and throw out the power steering.

I will now describe my process and it may not be the same as the tutorials. Forgive me if I confuse terms and names. Maybe someone will fix it later.

1. Removing the power steering. First, set the wheels to the straight position.
a. First, I drain the oil. To do this, slightly unscrew the oil pipe union at the outlet from the power steering - (that goes to the oil reservoir).
b. Disconnect the oil hoses (unscrew the bolts)
v. Disconnect from steering shaft and tie rods. It's simple on top, but a puller may come in handy below.
D. Unscrew the power steering and remove.

2. Analysis of the power steering. The main thing is to remember what was where.

A. First, remove the driven shaft.
To do this, unscrew the locking bolts that hold the side bearings, and remove the locking ring, where the shaft sticks out more and where you will knock out, then use a screwdriver and a hammer to rotate the side bearings so that the center of the driven shaft moves further from the main part of the power steering. In general, in order for the gears to move further differently, when you knock out the shaft, it will pull up the surfaces in the power steering case and then you have to grind it down in order to put new oil seals and they will not bulge. Then you just knock out the shaft. Be careful, roller bearings will sprinkle right away - do not lose them.

B. Now we disassemble the drive shaft.
To do this, unscrew the four screws on the top cover and remove the shaft.Then unscrew the nut of the lower bearing and remove it.

B. Disassembly of the drive shaft piston: (This is if the power steering wedges in both directions and generally does not work well). There is only one oil seal and it is never in the repair kits.

G. Change all the oil seals that you see with new ones. Be careful with the bottom PTFE. It can be stretched a little to dress. If you drag it, it will grab. The seals are located inside the side bearings on the shaft, and on the housing for the same bearings. One is on the piston and two on the top cap. Another one on the bottom of the drive shaft (I wrote about it above)

3. Assembling the power steering.
Everything is in the reverse order, only the upper cover is screwed on first, and then the lower bearing is put in and the lower bearing nut (with two holes) is screwed in until it stops. Then the driven shaft is installed. It is worth noting here that at first the upper bearing is assembled and put on the shaft, then the lower bearing is inserted into the power steering housing and locked with a retaining ring (again, the center of the driven shaft has shifted further from the main part of the power steering). Then the bottom bearing is formed and the shaft with the top bearing is carefully inserted. It is important that the rollers do not fall out into the power steering. You can check - shake. They will clatter inside the case. Then put the retaining ring.
After assembly, you need to check if nothing is interfering? To do this, you need to turn the drive shaft - it must make four turns.

4. Power steering adjustment. Unfortunately, I do it by eye.
First, I tighten the lower bearing until it stops. You have to turn it with a hammer and a punch (I couldn't find the key). But do not overtighten so as not to crush the bearings.
Then I bring the eccentrics of the side bearings. They should rotate in one direction, that is, if one is clockwise, then the other is counterclockwise), traces from the locking bolts can be a reference point - they must be combined with the bolts themselves. Then try to tighten it almost to the stop, but so that the rotation of the bearings is the same. It is also impossible to overtighten - the oil seals will quickly wear out.
Then stop.

5.installation of power steering
Everything here is the same as in parsing. The only thing is that the steering wheel is connected first, then turn the steering wheel all the way, and then two turns in the opposite direction - this will be the central position and then put on the bipod.

6. Oil filling and bleeding.
The car must not be started before filling with oil.
When you fill the tank full of oil, start the car, but do not turn the steering wheel. The oil will go away immediately. Top up until it stops leaving and there is less foam. Then turn the steering wheel a little to the sides (but not in place), this will expel the remaining air, a fraction of the level, and small bubbles will go away by themselves. And enjoy the soft work of the GUR.

Sorry for the unprofessional language. Maybe someone else will clarify something and suggest.
I went over my power steering 4 times for 150,000 km. Another 10 times on another machine. A friend helped and disassembled the drive shaft to the screws, but assembled it incorrectly. It took a long time to find the right combination.

Listen, I'm sorry, I didn't read your question right away.
New - not used? Or was it used and flowed? If not used, then it is better not to touch or disassemble, but to put and drive until it flows. And it flows from above, where the steering shaft enters. There the oil seal can be easily changed without removing the power steering.
And down through the side bearings on the driven shaft. if they are of the old model, then they need to be replaced with a new one with fluoroplastic gaskets - these do not flow longer.To do this, you need to disassemble the power steering.

But even so, it’s better not to climb the trains until it starts flowing. Power steering is disassembled only in case of leaks and poor performance.

Thank you very much and I did just that.
I put it down and don't touch it. It works, it doesn't flow, and glory to you Lyokh, who drove it to me-)))
Admins.
The GUR Bulkhead Council thinks that it should be posted for the information of all on public display.

Sergey, can you tell us more about the upper oil seal without removing the power steering, it flows right there. Thank you.

Sergey, about the regulation -
They should turn in one direction, that is, if one is clockwise, then the other is counterclockwise)
No mistake? And if both curry clockwise, what is the risk?

In other words, either both “from oneself” or “from oneself” depending on where to look, but threatens with a bias, they work as eccentrics.

Sergey, can you tell us more about the upper oil seal without removing the power steering, it flows right there. Thank you.

You disconnect the steering shaft, hoses, unscrew the four bolts on the cover and remove it, change the oil seal.
when installing the cover back, be careful with the O-ring, well, you screw everything back and connect it. Don't forget to upgrade.

And interestingly, the hydrolab puts in Moscow some kind of “own” repair kits. I now think that every new one needs to be touched up and look for good cuffs. Almost everyone is wedging: someone to the right, someone to the left, someone in all directions. The reason is the wear of the seals, not the pump and the high pressure flexible hose. https://my.housecope.com/wp-content/uploads/ext/2735/i137/1004/63/dbced.

Yes, they do. And with nova they also put their details. I installed the power steering at the beginning of 2008.Since then, I have not even added a drop of oil there.

You most importantly tell me how their seals work at speed, I mean the steering wheel became wadded at speed or how was it? They write that when they are bulked up with their repair kits, the steering wheel becomes as it should be-wadded at speed. What about you?

... guys, and another question, what is wearing out in the power steering pump?, what can you change there? Especially cold. Will fill "dikstron".

can the belt slip? the backlash can be checked at the pump shaft.

... guys, and another question, what is wearing out in the power steering pump?, what can you change there? Especially cold. Will fill "dikstron".

Basically, the rotor blades are worn out, but the noise may not be due to them, the filter, valve, air in the system is clogged.
The belt usually “squeals”.

We remove the steering gear (see. Removing the power steering gear) without removing the bipod and the extension of the supply hose.

Clamp the mechanism in a vice with the fittings down and drain the remaining oil into the container, turning the mechanism shaft with the key "17".

If at the same time axial play of the shaft is felt, adjust the thrust bearings. For this…

… Through a bit or a punch, we straighten the collar of the adjusting nut, which is nailed into the grooves of the crankcase.

With a special wrench, turn the nut clockwise until the gap is eliminated.

In this case, we control the torque of the shaft, which should be no more than 0.2 kgf.m. For this…

… With a dynamometer hooked onto the “17” key, we measure the turning moment of the spool shaft.

With a lever length equal to 200 mm, the force should not exceed 1.0 kgf.

Bend the collar of the nut into the groove with a beard.

We swing the steering mechanism bipod with our hand.

If you feel a gap, adjust the gearing.
For this…

… Remove the bipod from the sector shaft (see Removing the power steering gear).

Prying off with a screwdriver or a knife blade, remove the top ...

Using the "13" wrench, unscrew the lock nuts of the locking bolts.

Using a 12 key, unscrew the locking bolts by 2-3 turns.

With a special key, we turn the adjusting eccentric rings of the shaft-sector bearings.

ATTENTION
When adjusting, it is necessary to exclude the possibility of misalignment of the shaft-sector, therefore, we turn the clips alternately at a small angle until the clearances in the engagement are eliminated.

Install the steering gear in reverse order.

Steering wheel remover

The steering wheel is firmly seated on the splines of the steering shaft and it is not easy to remove it. Doing this job will make a homemade puller easier. Plate material - steel, standard bolts. When making a puller, you can do without welding. For this, we use a plate with a thickness of at least 6 mm. In it we cut the threads for the central bolt.

The purpose of the power steering is to provide more comfortable steering wheel control. Today, the power steering system is installed on the Gazelle and on many modern cars. You can learn more about the device, malfunctions and unit repair at home from this material.

Both the electric power steering on the Gazelle and the power steering are designed for more comfortable steering. First, let's take a look at the power steering device on the Gazelle. We are talking about both the Gazelle Business with a 405 engine and other models of this line.

So, what is the device of the system:

Power steering pump. This element of the circuit ensures optimal circulation of the consumable in the system, as well as pressure.
Steering gearbox with distribution element. This device allows you to provide an air flow necessary to direct the oil into the desired cylinder cavity or back into the tank.
Another component of the system is the cylinder. With its help, the conversion of the pressure of the consumable material into the movement of the piston, as well as the rod, is ensured.
The consumable itself, that is, oil. The fluid transfers the force from the power steering pump to the cylinder. In addition, the oil provides lubrication for all rubbing elements of the device.

Like any unit, the power steering can fail from time to time.

The main malfunctions and methods of their elimination are given below:

The system drive strap is worn out or is not tight enough. In this case, the belt is either changed or its position is adjusted.
The steering wheel turns poorly, this can be due to both wear of the strap and a low oil level in the system, a reduced number of engine revolutions, a clogged filter. In addition, the problem may be low pump pressure or an air lock in the lines. Depending on the problem, the solution may be to add consumables, adjust the idle speed, change the filter, or repair the pump. It will not be superfluous to check the tightness of the connections.
Mechanical failure in the operation of the steering system, you need to diagnose it.
If the pump does not work, you need to either repair it using a repair kit, or change the oil seals.
Steering elements are worn or the drive geometry is broken. Defective parts should be replaced.
If the hydraulic fluid is discharged through the relief valve, locate the leak and fix the problem.The reason may lie in the inoperability of the pump, you should check its working pressure.
Damage or wear of tires, it is necessary to identify the faulty elements and replace or repair them.

As you might have guessed from the previous paragraph, if the power steering on the Gazelle does not work, then this is due to the pump. To repair this element in a car with your own hands, you will need to purchase a repair kit in advance. You can buy it at any thematic store. The main difficulty in repair is that the pump is not collapsible.

The repair procedure is carried out as follows:

Dismantle the pump and disassemble in accordance with the instructions that come with the kit.
Clean the device from dirt, it is possible that there will be kinds of reasons for the failure on the case. Usually the problem lies in the wear of the oil seal, then it will be necessary to change it. When installing a new oil seal, the roller must be modified.
The gland can be installed in several ways. You can build a special recess on the outer part of the element, drill a corresponding threaded hole in the wall of the device, and then fix the gland with screws. You can also fix this part in the middle of the pump using the specially bent body ends.
When the replacement of the element is completed, it will be necessary to reassemble the system in reverse order. Please note that after the repair is completed, when the power steering is operating, you may hear an uncharacteristic noise for this. This is a grinding in of a new oil seal, so you should not worry about this. When the repair is over, it is necessary to change the oil in the system.

The steering gear on Gazelle cars is installed regardless of the presence of a hydraulic booster. It increases the reliability of movement, the safety of the driver and passengers. Consider the symptoms of malfunctions and methods of adjusting the Gazelle steering gear.

Control assemblies wear out in the first place, as they constantly experience severe stress. The steering gear in this respect is the most risky unit. After a certain period of operation, signs of wear appear:

The occurrence of extraneous knocking or vibration felt by the driver through the steering wheel.
Significant steering effort is required.
The backlash is more than 20 ° for passenger vehicles or 25 ° for trucks.
The appearance of an oil leak from the gearbox. To some extent, oil is always present on the body, but a noticeable discharge is a sign of failure of the oil seals.

The fact of the presence of these signs indicates that adjustment of the Gazelle steering gear is required. You should not delay with this procedure, since some malfunctions inevitably create the basis for the appearance of even more serious problems.

The composition of the Gazelle control unit:

A wheel mounted on a shaft and located inside a column that has the ability to adjust the height and angle of inclination.
Swing mechanism.
Drive unit.

Repair of the steering Gazelle is carried out as needed, mainly when the first signs of a malfunction appear.

The gearbox mechanism is compact and simple enough. The work does not require high qualifications, but it should not be taken as the first step in setting up.

The fact is that in order to remove the problem node, you will need:

Dissolve the front wheel mountings
Hang up the front axle, support it.
Knock out traction.
Remove the gearbox with the bipod.

Since these actions are quite difficult, the process of adjusting the steering gear must be started after some preparatory operations:

Checking the rod ends.
Camber-toe adjustment.
Adjusting the position of the column and driver's seat.

Adjusting the steering on the Gazelle begins with adjusting the backlash. The plastic casing is removed, 4 fastening bolts are unscrewed with a 13 head and the metal protection is removed.There are shims under it, with the help of which slack is eliminated.

One gasket is removed, the assembly is assembled, and the presence of backlash is checked. If it has not disappeared, then the procedure is repeated until the slack is completely eliminated. You need to check it with the middle position of the steering wheel, when it is minimal. The adjustment is carried out until the maximum ease of rotation of the shaft with minimum backlash is reached.

After eliminating the backlash, the repair of the steering Gazelle continues. Adjustment of the clearance of the ball nut with the shaft-sector. To do this, put a bipod on the shaft, turn the steering wheel shaft 2.5 turns in either direction, check for free play. If there is one, you will have to adjust the position of the bearings. Angular contact bearings are used there, so the size of the clearances should be minimal (ideally, absent).

A noteworthy circumstance is that the ball nut with the screw cannot be dismantled, which in the first years of operation of the Gazelle car was a significant drawback due to the lack of spare parts. Today this issue has been completely resolved, the market has a sufficient number of parts, which allows repair or adjustment at the first symptoms of a malfunction.

The following malfunctions were identified during the actual operation of the power steering systems on Volga 3110 and 3102 vehicles.

These malfunctions mainly relate to the power steering units themselves. Front suspension malfunctions are not mentioned. Some more malfunctions of the steering and information on the power steering device are given in the brochure "Steering of GAZ-3110 and GAZ-3102 with a hydraulic booster", Koleso publishing house, Moscow, 2000.
