In detail: do-it-yourself repair of the power steering uaz patriot from a real master for the site my.housecope.com.
Power steering power steering, device, repair, operation.
Attention! A proven method!
With the help of a modified pump puller VAZ 01-07 (worth a penny) and two M8 bolts 65 mm long. When working, consider three points
1.holes in the steering wheel hub are not drilled through 180 degrees
2.Cut off the jumper between the hole and the end of the puller with a grinder
3.Fake steering wheels do not have technological holes in the hub and this method will not help
Notes:
1. On sale there are pump pullers of different thickness - the correct one is the one> = 10mm.
2. Before you pick up the grinder, you need to try on the puller on the handlebars and outline the direction of future cuts. The grinder 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 rip off)
Press down with the screw (M10) included in the puller kit.

The same problem came up. I had to throw the steering wheel over a couple of slots, so I could not remove it. I had to disconnect the steering shaft and rearrange it in the splines. There is a barbaric way, but this steering wheel is painfully flimsy for him to the touch. You can unscrew the retaining 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 fittings from a nut screwing onto the steering shaft by half of its thread and a bolt screwing into this nut. And it is more convenient to knock on the bolt.

I have one that they put on the latest new UAZs, so it can be removed with a puller without problems. There, under the plastic patch, there are two special holes for this purpose.
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 on 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 vernier caliper.
A 15x15 corner is taken, a piece of length 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), it is applied to the steering shaft and wrapped into the holes through the corner that there were two fools bolt М8. The bolts pull the steering wheel towards themselves, and the corner, respectively, rests on the shaft, the steering wheel is pulled together. I changed mine from the usual to the luxury one. And I wanted to help my friend remove the new steering wheel on the zero car - so he unscrewed his head nafig on one bolt - then he spent an hour turning out the stub - so make up your mind.
Before shooting, pour VDshka or Unisma! It will go easier !!

It is pulled up by a simple device made from a sheet of an old spring. You take a leaf of the spring and bend one edge of it (cm 5-7) under 90 degrees. With this thing, the steering tips are very easy to tighten, 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 vice, release the plugs (by unscrewing or twisting, if necessary. I tightened harder than in the primer - all the way and 1/4 back. everything is OK.By the way, even the new tips are wrapped 2.5 turns.

To adjust the gearbox, unscrew the cap nut on the side of the gearbox housing (a large one, a key for 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 the reverse order. It is also necessary to check the condition of the ends of the steering rods, very often the steering backlash is due to them.
Before adjusting the steering wheel - to the central position and tighten not according to the very "I do not want", but wisely. The witness himself, when the worm in the over-tightened gearbox was biting into extreme positions.Very unpleasant, especially on the road.

It so happened that on my 91 thousand "loaf" the resource of the steering gear was completely exhausted. 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 the entot device. I read the ABC book, bought a new gearbox. and on Saturday together with a friend began to poke around. 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 the neighboring garages looked at this operation in a strange way. Next, you need to remove the steering bipod. 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 bipod and separate these parts with the blows of a 10-kg sledgehammer on the steering bipod shaft. The remnants of the old gearbox were thrown away, the transmission synthetics (GL5) were poured into the new one and everything was put in place.

UAZ does not produce military bridges + power steering vehicles (except for "Bars"). In my opinion, the problem is that military bridges have a greater angle of rotation of the wheel (or it is known that the power steering is unreliable.) not one of the strongmen), on bumps I try not to turn the steering wheel too much unnecessarily (or do I see some special bumps?) [Commodore]
I have had a power steering for a year (with military bridges), and I must say that I am very pleased with it.
1. The car has excellent maneuverability - since the angle of rotation of the wheels of the military is greater, the light steering wheel when parking allows you to turn literally on the spot. Try to do the same operation without power steering.
2. On the track, the car reacts less to unevenness, it is easier to keep it on a straight line, and there is 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 the Ulyanovsk all-terrain vehicles, but a feature inherent in all short-range vehicles. So far I have been driving the "goat" and have not noticed any yaw. Hands themselves already automatically corrected the movement of the car imperceptibly for me. But as soon as I took a ride in a long-wheelbase car, I was horrified when I got into my own “goat”. And before that I went and did not notice.
The problem can be solved, but only in a complex. Install a steering damper, good shock absorbers, eliminate all backlash in the steering rods, gearbox, swingarm, bearings, etc. and install good tires. It will get much better. But it won't be perfect anyway, it's not VW. You just have to get used to it. Do not think that if the car is new, then there is still no backlash. That is why (because the car is new) it is still very poorly made. Everything must be checked and tightened / changed / adjusted. If done by hand, everything will be fine.
1. Eliminate imperfections and backlashes. 2. Get used to 3. Not voiced by previous speakers: there are Guras with, so to speak, with a "minor" drawback - the actuation of this device with a slight delay, with zero information content of the steering wheel, this leads to "overrun".

In fact, it is more reliable, and by the way and cheaper, imported from disassembly, for example from Chevrolet. In Vadik's "Black Cuttlefish", for example, there is, after two of our untimely dead.
I myself got myself a hydrach on a UAZ, I attached a W-123 body from Merce. I installed the gearbox without any problems, but I had to tinker with the pump. Put it together with the steering column and all the switches and the ignition switch! And it took about two days, taking into account all the preparatory work!
The product of joint production of OJSC “Avtodetal-Service” (Ulyanovsk) and the firm “ZF Lenksysteme” (Germany) for the production of a Steering gear with a hydraulic booster (31608-3400500) (hereinafter “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 rack assembly, needle injection and drain hoses, an oil tank, a tank clamp, a bracket, a pump holder, a poly V-belt pulley , fasteners.
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; to the right 2.6 kgf;
2. Speed of self-return of the steering wheel: 246 degrees / sec;
3. Changeover speed: 76.1 km / h;
4. Speed of turning R 35 m: 69.5 km / h;
5. The gear ratio of the steering mechanism: 17.23.
The sale of a complete set of power steering gear is made by Tehresurs LLC.

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

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

According to rumors, Sterlitamak is of better quality than Borisov, although it is "tighter" (the gear ratio is less). Outwardly, the Sterlitamak hoses run one after the other from above, while the Borisov hoses run one on top and one on the side.
According to the Ulyanovsk craftsmen, the Borisov power steering is more reliable. Also, power steering, in my opinion, differ in the number of revolutions of the steering wheel (3 and 5).
The Borisov power steering is really very powerful, even on 35s with -19 discs it turns without feedback. But Sterlitamak is much more informative.
The plant does not make wagon-type cars with power steering - the issue is being resolved; cars of a wagon layout, on gear axles and with power steering (and without power steering) does not at all.
Everything turned out surprisingly well for me. Although at first I found out that power boosters are not put on a loaf. But there was no strength to fight with the steering wheel (especially on the off-road) and decided to mount the usual UAZ hydraulic booster by means of a cunning bracket. From Ulyanovsk, they brought me a factory kit for installation on the UAZ-31514. When I found out what these hydraulic boosters are doing in Belarus in the glorious city of Borisov, we decided to go to the plant 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 stamping of the body had to be changed for this wetsuit. So they came back with these gidrikas (luckily for us). In short, we bought ourselves one for $ 50. Became like a native. With the steering column, I was a little perverted - I put MAZovskaya, with an adjustable tilt. As for the stamping, there was no need to cut the floor. car lifted 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 turn on the spot, and on the track, but it returns to zero itself, just hold it. The same is bad - on bumps it “responds” with lightning speed and mercilessly - I, having broken two fingers with an 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 - Borisov or "luxury" has a powerful gearbox, due to which it is less sensitive, does not hit the hands, does not require strong steering on the track at high speeds. But it turns tighter than the first one and returns to zero itself less intensely, 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 by which human physical labor is facilitated. All that a person needs is to hold the steering wheel in his hands, and you can even control it with one finger. In this material, we will consider the purpose of the power steering, as well as its structure and the principle of 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 situation while driving. In addition, prolonged driving would lead to rapid driver fatigue. Therefore, a device was developed that made it possible to facilitate human labor.
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 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 that the wheels turn under the influence 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 working fluid into the required cavity of the hydraulic cylinder. The distributor is the device by which a certain amount of fluid is directed to the hydraulic cylinder or reservoir.
Tank 6 is a plastic reservoir for storing and adding working fluid to the system. In addition to the liquid, the reservoir also contains a special filter and an oil control dipstick.
It is impossible to do without connecting hoses in the design of the power steering steering wheel on the UAZ Patriot SUV. These hoses are designed to work under high pressure, therefore, they must ensure high tightness of the system.
The circulation of the fluid by means of hoses is provided between the hydraulic cylinder and the distributor. Low pressure hoses allow fluid to flow from reservoir to pump and from distributor to reservoir.
The operation 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 making a maneuver, the spool moves, whereby the drain lines are opened. When a certain line is opened, the oil moves under pressure to the required areas of the device. The fluid exerts pressure on the piston, which ultimately drives the turning of the wheels. When the driver stops turning the steering wheel, the spool stops and the neutral position of the distributor body stops.
Liquid flows from the discharge line to the drain line, whereby the pump pumps oil through the system. In the event of a failure of the hydraulic pump, the loss of vehicle control is not lost at all, which is another advantage of this mechanism.
Each mechanism tends to break down and the power steering on the UAZ Patriot SUV is no exception. The reasons for the repair are the following signs:
- The appearance of extraneous noise from the device.
- The appearance of an oil leak on the elements of the mechanism.
- Microcracks on low and high pressure hoses.
- Increased steering effort.
- Reducing the level of liquid in the reservoir.
Repair of the power steering of the UAZ Patriot SUV can be done by hand, but it all depends on the type of malfunction, so you need to first find out the reason. There are the following reasons for which the device needs to be repaired:
