Do-it-yourself power steering repair UAZ Patriot

In detail: do-it-yourself power steering repair UAZ patriot from a real master for the site my.housecope.com.

Power steering GUR, device, repair, operation.

Attention! Proven method!
With the help of a modified puller for the VAZ 01-07 pump (Costs a penny) and two M8 bolts 65 mm long. Three things to keep in mind
1. the holes in the steering wheel hub are not drilled through 180 degrees
2. grinder cut off the jumper between the hole and the end of the puller
3. fake steering wheels do not have technological holes in the hub and this method will not help
Notes:
1. On sale there are pullers for the pump of different thicknesses - the correct one is >= 10mm.
2. Before picking up a grinder, you need to try on the puller on the steering wheel and outline the direction of future cuts. The Bulgarian will have to work seriously.
3. Screw the bolts (those that are M8) into the holes on the steering wheel and necessarily lock on the reverse side with nuts. (otherwise the thread will break)
It is necessary to press with the screw (M10) included in the puller kit.

The same problem arose. It was necessary to throw a steering wheel on a couple of slots, so I could not remove it. I had to disconnect the steering shaft and rearrange it in the slots. There is a barbaric way, but this steering wheel is too flimsy for him to touch. You can unscrew the fixing nut, disconnect the shaft and loosen the steering column bearing. One pulls the steering wheel towards itself, and the other hits the end of the steering shaft with a heavy hammer. You can make a fixture out of a nut screwed onto the steering shaft for half of its thread and a bolt screwed into this nut. And it is more convenient to knock on the bolt.

I have the one that they put on the latest new UAZs, so it can be removed with a puller without any problems. There are two special holes under the plastic blotch for these purposes.

Everything is very simple - you need a thick (5-6 mm) plate with two holes for M8 bolts screwed into the steering wheel hub. The plate rests against the shaft, the bolts are tightened, the wheel is pulled together. You can drill holes in place by measuring the distance between the holes with a caliper.

A corner 15x15 is taken, a piece is sawn off from it

20 cm. In it, in turn, 2 holes are drilled at a distance the same as the holes in the steering wheel (2 threaded holes into which the bracket for the bibical is passed), applied to the steering shaft and wrapped into the holes through the corner, which was two dope bolt M8. The bolts pull the steering wheel towards themselves, and the corner accordingly rests against the shaft, the steering wheel is pulled together. I changed mine from regular to deluxe. And I wanted to help a friend remove the new steering wheel on a zero car - so he unscrewed his head on one bolt - then he tormented the stub turning it out for an hour - so make up your mind.

Before shooting, water with VDshka or Unisma! Go easier!!

It is pulled up with a simple device made from a sheet of an old spring. You take a leaf of the spring and bend one edge of it (see 5-7) under 90 degrees. This thing very easily tightens the steering tips, only the wheels must be removed so that they do not interfere.

Can be tightened with a chisel. To do this, you will have to remove the rods (not the tips, but all the rods - while the convergence will not suffer) and holding the hinges in a vise, move the plugs (unscrewing or twisting if necessary. I tightened it more than in the primer - until it stops and 1/4 back. While everything is ok.By the way, even the new tips are screwed in by 2.5 turns.

To adjust the gearbox, it is necessary to unscrew the cap nut on the side of the gearbox housing (a large one, a key of 28 or 30, I used an adjustable one), remove the lock washer, tighten the adjusting screw with a “square” until the backlash is eliminated and assemble in reverse order. It is also necessary to check the condition of the tie rod ends, very often the steering play is due to them.

Before adjusting the steering wheel - to the central position and tighten not according to the most “I don’t want to”, but wisely. The witness himself, when the worm in the overtightened gearbox bit in extreme positions.Very annoying, especially on the road.

It so happened that on my “loaf” at 91 thousand the resource of the steering gear was completely over. That is, the backlash was not eliminated by the adjusting screw, moreover, it became very tight to turn the steering wheel. In short - I decided to change this device. I read the primer, bought a new gearbox. and on Saturday, together with a friend, they began to tinker. The first thing they ran into was the removal of the steering wheel. You need a special puller, and instead, only a set consisting of a hammer and a sledgehammer and a long list of obscene expressions. After an unsuccessful hour of work with this set, the commander's decision came to cut off the steering column with a “grinder”. No sooner said than done, only the people from neighboring garages somehow looked strangely at this operation. Next, you need to remove the steering arm. There was a puller for this operation, but in the process of its implementation it was gone. I had to remove the cover with the adjusting screw, insert a “locomotive” key between the gearbox housing and the steering arm and blows a 10-kilogram sledgehammer on the steering arm shaft to separate these parts. The remains of the old gearbox were thrown away, transmission synthetics (GL5) were poured into the new one and everything was put back in place.

UAZ does not produce vehicles equipped with military bridges + power steering (except for Bars). In my opinion, the problem is that military bridges have a larger wheel turning angle (or it is known that the power steering is unreliable.) On the highway, with the right convergence-camber, the power steering is not needed (on the Moscow Ring Road, I hold the steering wheel with my hand by the spoke for “weighting” - and I not one of the strongest), on bumps I try not to turn the steering wheel too hard (or do I encounter some special bumps?) [Commodore]

I have had power steering for a year now (with military bridges), and I must say that I am very pleased with it.
1. The car has excellent maneuverability - since the military has a larger turning angle of the wheels, the light steering wheel when parking allows you to spin literally on the spot. Try to do the same operation without GUR.
2. On the track, the car reacts less to bumps, it is easier to keep it on a straight line, and there is a zero, although not the same as on foreign cars.
3. Off-road is easier than an example - over bumps and ruts!

In my opinion, this is a matter of habit. There is one more thing. What did you drive before? The base is short, so it prowls along the road. This is not even a generic feature of Ulyanovsk all-terrain vehicles, but a feature inherent in all short-wheelbase vehicles. So far I have ridden the “goat” and have not noticed any yaws. The hands themselves were already automatically correcting the movement of the car imperceptibly for me. But as soon as I drove a long-wheelbase car, I was horrified when I sat down in my own “goat”. And before that I went and did not notice.

It is possible to solve the problem, but only in a complex. Install a steering damper, good shock absorbers, eliminate all play in the steering rods, gearbox, swing arm, bearings, etc. and install good tires. It will get much better. But it still won't be perfect, it's not a VW. You just need to get used to it. Do not think that if the car is new, then there are no backlashes yet. That is why (because the car is new) it is still very badly done. Everything needs to be checked and tightened/changed/adjusted. If you do it by hand, everything will be fine.

1. Eliminate imperfections and backlash. 2. Get used to 3. not voiced by previous speakers: there are Gura with, so to speak, with a “minor” drawback - the operation of this device with a slight delay, with zero information content of the steering wheel, this leads to “re-steering”.

In fact, it is more reliable, and by the way, cheaper imported from disassembly, for example, from Chevrolet. For example, Vadik has one of these on the “Black Cuttlefish”, after two of ours who died untimely.

I made a W-123 body from Merce on my UAZ. The gearbox was installed without problems, but I had to tinker with the pump. Put together with the steering column and all the switches and the ignition! And it took about two days, taking into account all the preparatory work!

A joint product of Avtodetal-Service OJSC (Ulyanovsk) and ZF Lenksysteme (Germany) for the production of Power steering gear (31608-3400500) (hereinafter referred to as the “Mechanism”) for UAZ cars of the brand: passenger cars 3160, 3162, 3163 and cargo UAZ 2360-Pickup.

The complete set of the “Mechanism” includes parts manufactured by ZFLS (Germany): a high-pressure pump, a distributor with a screw and a piston with a rail assembly, needle inlet and outlet hoses, an oil tank, a tank fastening clamp, a bracket, a pump holder, a V-ribbed pulley , fixture.

Test tests gave the following results (tests were carried out on a serial UAZ-31622):
1. Effort on the steering wheel: to the left 2.0 kgf; right 2.6 kgf;
2. Steering wheel self-return speed: 246 deg/s;
3. Repositioning speed: 76.1 km/h;
4. Cornering speed R 35m: 69.5km/h;
5. Gear ratio of the steering mechanism: 17.23.

You can rotate, but it is undesirable to drive like that for a long time. This option was from the factory - a gearbox from the power steering, but there was no pump and other things. He traveled several thousand - then the play in the gearbox increased.

The invention is not mine, it is from the ancients and chorus. forgotten "experienced advice". In quality anthers USE covers of ball pins from ZAZ-968 A, M, slightly cutting them off from above.

According to rumors, the Sterlitamak one is better than the Borisov one, although it is “tighter” (the gear ratio is less). External difference - for Sterlitamak hoses go from above one after another, for Borisov - one from above, one from the side.

According to the Ulyanovsk masters, the Borisov GUR is more reliable. Also GURs, in my opinion, differ in the number of turns of the steering wheel (3 and 5).

Borisov power steering is really very powerful, even on 35s with -19 discs it turns without feedback. But Sterlitamaksky is much more informative.

The plant does not make wagon-mounted cars with power steering - the issue is being resolved; wagon layout cars, on gear axles and with power steering (and even without power steering) do not do it at all.

It worked out surprisingly well for me. Although at first I learned that hydraulic boosters are not put on a loaf. But I didn’t have the strength to fight the steering wheel (especially off-road) and I decided to attach an ordinary UAZ hydraulic booster using a cunning bracket. From Ulyanovsk, they brought me a factory kit for installation on a UAZ-31514. When I found out that these hydraulic boosters are made here in Belarus in the glorious city of Borisov, we decided to go to the factory with a mechanic to consult. And lo and behold - it turns out a month ago, the factory workers made 5 hydraulic boosters specifically for loaves and went to Ulyanovsk to offer them to UAZ, but UAZ refused this development under the pretext that the body stamping had to be changed for this hydraulic. So they came back with these gidriki (for our happiness). In short, we bought ourselves one for $50. Became like a native. With the steering column, I perverted a little - I put MAZovsky, with adjustable tilt. As for stamping, there was no need to cut the floor. machine liftovannaya under the 33rd rubber.

There is the most traditional rack and pinion worm gearbox, it is good precisely because it is light - it is easy to spin on the spot, and on the track, and it returns to zero itself, just hold on. The same is bad - on bumps it “answers” ​​with lightning speed and ruthlessly - I, having broken two fingers with the old three-spoke steering wheel, put a weighted two-spoke steering wheel (in general, in my opinion, it is the most convenient of the existing ones).

The second option - Borisovsky or "luxury" has a powerful gearbox, due to it it is less sensitive, does not hit on the hands, does not require strong steering on the highway at high speeds. But it spins tighter than the first one and returns to zero less intensively, which, at least, annoys me.

The UAZ Patriot car in the design of the steering mechanism has a device that is popularly called power steering or hydraulic power steering. The hydraulic booster is a device through which human physical labor is facilitated. All a person needs is to hold the steering wheel in his hands, and you can control it even with one finger. In this material, we will consider the purpose of the power steering, as well as its device and the principle of carrying out repair work on the UAZ Patriot SUV.

The main purpose of the power steering device is to facilitate driving. Thanks to the power steering on the UAZ Patriot SUV, turning the steering wheel is much easier and more comfortable. After all, turning the steering wheel without an amplifier on such a 2-ton car is quite difficult, and this can provoke the development of an emergency while driving. In addition, prolonged driving would lead to rapid driver fatigue. Therefore, a device was developed that made it possible to facilitate the work of a person.

The hydraulic booster is a complex mechanism, which includes the following main devices:

Consider the purpose of each of these power steering elements.
Pump 1 serves to be able to maintain pressure and circulate the working fluid through the system. The pump is a mechanism that is attached to the car's engine and is driven by a belt drive from the SUV's crankshaft.

The hydraulic cylinder is designed to ensure the rotation of the wheels under the action of fluid pressure. The hydraulic cylinder is built into the system of the steering mechanism 3, whereby the performance of this function is ensured. Below is a structural diagram of the power steering device on a UAZ Patriot car.

Distributor 2 is designed to distribute the flow of the working fluid into the required cavity of the hydraulic cylinder. The distributor is the device by which a certain amount of liquid is directed to the hydraulic cylinder or reservoir.

Tank 6 is a plastic reservoir for storing and adding working fluid to the system. In the tank, in addition to the liquid, there is also a special filter and an oil control dipstick.

It is impossible to do in the design of the power steering on the UAZ Patriot SUV without connecting hoses 5. These hoses are designed to work under high pressure, therefore they must ensure high tightness of the system.

Fluid circulation through hoses is provided between the hydraulic cylinder and the distributor. Low pressure hoses ensure fluid flows from the reservoir to the pump and from the distributor to the reservoir.

The functioning of the power steering on the UAZ Patriot SUV is based on the movement of the spool when the steering wheel is rotated in different directions. During the rotation of the wheel, when performing a maneuver, the spool moves, thereby opening the drain lines. During the opening of a certain line, oil moves under pressure to the necessary areas of the device. The fluid exerts pressure on the piston, and it eventually drives the wheels to turn. When the driver stops turning the steering wheel, the spool stops and the neutral position of the distributor body stops.

There is a flow of fluid from the discharge line to the drain line, whereby the pump pumps oil through the system. In case of failure of the hydraulic pump, the loss of control of the car is not lost at all, which is another advantage of this mechanism.

It is common for every mechanism to break down, and the power steering on the UAZ Patriot SUV is no exception. The grounds for repair are the following signs:

  1. Appearance of extraneous noise of the device.
  2. The appearance of an oil leak on the elements of the mechanism.
  3. The occurrence of microcracks on low and high pressure hoses.
  4. Increasing the effort that must be applied to the steering wheel.
  5. Decreased fluid level in the reservoir.

Repair of the power steering of the UAZ Patriot SUV can be done by yourself, but it all depends on the type of malfunction, so you need to first find out the cause. There are the following reasons why the device needs to be repaired:
