Installation on the UAZ patriot gur rudder. Description gur on UAZ

Step-by-step installation of the power steering on the UAZ 469 The effect of using the power steering cannot be exaggerated. It helps to reduce the physical load on the driver when driving off-road by 2-3 times. This is the best tuning for UAZ. This is especially noticeable when driving for a long time in difficult road conditions. The original power steering kit includes all the necessary parts. Algorithm for performing work: 1. Remove the steering wheel. 2. Remove the steering column together with the cardan joint. 3. Unscrew the nut and disconnect the tie rod from the bipod. 4. Unscrew 3 steering gear bolts. 5. We put the bipod from the kit on the shaft of the new steering mechanism with power steering and tighten the nut of its fastening. 6. We install a new steering mechanism in place of the old one and fasten it with 3 bolts. 7. We connect the bipod with the tie rod. Tighten and split the fastening nut. 8. We cut off the old steering column mounting bracket, it will interfere with the installation of a new one. 9. We put the plastic nozzle from the kit on the new steering column, fix it with glue. 10. We install the contact screw and the beep bushing from the old column into the nozzle. 11. We fasten the metal column support from the kit to the car body with M6 bolts. 12. We put on a new column a rubber ring, a washer and a castle nut, after that we insert it into the support and fasten it with a stepladder. 13. Insert the cardan shaft from the kit between the column and the steering gear. We combine its hole for the wedge from the kit. We determine the inlet (the widest) and hammer the wedge with light hammer blows through the punch. 14. We put ordinary and spring washers on the thread of the wedge and lock it with a nut with a cotter pin. 15. We fasten the splines of the other end of the new shaft in the same way as the old cardan was fixed. 16. We fix the steering column completely. The length between the shaft hinges should be 30 cm. 17. Tighten the castellated nut and install the steering wheel. 18. We connect the wires, adjust the position of the horn bushing. The steering gear has been replaced, you can continue installing the power steering parts. INSTALLATION OF THE PUMP AND POWER RESERVOIR Procedure: 1. Remove the cooling fan, crankshaft pulley and drive belt. 2. Unscrew the pump bolts and fasten the radiator fan to the water pump hub using the spacer from the kit and longer bolts. 3. Install the power steering pump pulley in place of the crankshaft pulley so that the ignition mark looks back in the direction of the car. 4. Fix the new pulley with longer bolts. 5. Unscrew the bolts and remove the fuel filter together with the bracket. In its place, install the power steering bracket. 6. Unscrew the top nut of the pump and install the bracket from the power steering kit on the stud with the eye back. Then screw the nut back on. 7. We fasten the pump with a strap on the bracket and insert the stop with the tip and the lock nut between the bracket and the bracket. We connect the bracket and the bar with a bolt from the kit. 8. We put the power steering belt on the pulleys and adjust its tension. To do this, we achieve parallelism of the axes of rotation of the pulleys, limiting the bending of the bracket by turning the stop out of the tip. Normal deflection of the belt should be in the range of 12 - 17 mm when pressed by hand. It should be placed perpendicular to the plane of the pulleys. 9. After the belt tension is adjusted, finally tighten all the pump mounting bolts and lock the stop and tip with a lock nut. 10. Install the fuel filter in the square hole. The pump is installed, after that it is necessary: ​​to drill 3 holes in the left mudguard of the engine compartment, attach a bracket to the mudguard and use a clamp, bolts and nuts to fix the tank on it; connect the tank with the pump and steering gear with polymer hoses; pour multigrade gear oil into the system; turn the steering wheel in both directions until it stops (hanging the front wheels) to remove air from the system; start the UAZ 469 engine, check the operation of the power steering and, if necessary, add fluid to the reservoir. If the oil in the reservoir foams when the engine is running, it means that the system is leaking. Stop the engine, seal the hoses and bleed the system again.

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:

1. Pump.
2. Hydraulic cylinder.
3. Distributor.
4. Connecting hoses.
5. Tank for filling the working fluid.

Consider the purpose of each of these power steering elements.
The 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 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 tank.

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 principle of operation of the device

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.

Grounds for repairs

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.

You can repair the power steering of the UAZ Patriot SUV with your own hands, but it all depends on the type of malfunction, so you first need to find out the cause. There are the following reasons why the device needs to be repaired:

1. If an uncharacteristic noise of its operation occurs in the mechanism of the device, then this indicates wear of the bearing elements. In this case, they should be replaced. But, besides this, extraneous noise can be caused due to the ingress of a third-party substance into the liquid or when filling the system with an unsuitable liquid.
2. If leakage of the working fluid is detected, then the place of such an action should be found. At the same time, it is important to examine all the junctions of the hoses, where most often the working fluid leaks.
3. If the oil level in the power steering reservoir decreases, then this indicates the need to replace the reservoir or connecting hoses soon.
4. The presence of microcracks on high pressure hoses is a key sign that the device may soon fail during operation. Therefore, during prophylaxis, if cracks are found on the hoses, the latter must be replaced. Repair of high pressure hoses is not carried out and after their wear, they must be disposed of.
5. With an increase in the load on the steering wheel, the hose breaks, which requires immediate replacement.

If you resort to device integrity verification measures, it is important to perform a number of the following actions:

• check the fluid level in the tank;
• check the condition of the tank;
• check the integrity of the hoses for microcracks and oil leaks;
• check the integrity of the pump;
• check the condition of the fluid in the tank.

Power steering repair on a UAZ Patriot SUV usually includes seals, bearings and hoses, and can be done independently.

More complex repairs with the failure of a pump, distributor or hydraulic cylinder are best left to professionals. At this stage, we can summarize and note that the power steering on the UAZ Patriot is a key element between the steering and the driver, so the health of this device is displayed mainly on the safety of passengers and the driver.

You can check your CBM and reduce it if needed!

Today, many modern cars are equipped. The purpose of this system is that its use allows you to more comfortably control the machine due to the facilitated rotation of the steering wheel. Therefore, many motorists whose cars are not equipped with power steering put power steering on their cars.

Hydraulic booster or electric power steering on UAZ: which is better?

The UAZ power steering is a relatively inexpensive system - its installation is more appropriate for large cars, as well as inexpensive cars. This is perhaps the main advantage of the system. Another advantage is the power reserve of the GUR, which is higher, unlike the EUR, so SUVs and minibuses are equipped with such systems.

As for the disadvantages of power steering:

1. If you put on UAZ power steering, then you will need to regularly monitor the level and condition of the consumables in the tank - you need to remember that the fluid requires periodic replacement.
2. You must always follow the rules for using the system in order to prevent its failure.
3. The operation of the unit should always be controlled by the car owner - for optimal functioning, you need to monitor the condition of the straps and pipes. In addition, the power steering pump must always be in working condition - no leaks or cracks are allowed. If problems arise in the operation of the unit, this is fraught with the repair of the power steering.
4. The functioning of the power steering largely depends on how the power unit works. That is, if the engine is not running, it will be extremely difficult to turn the steering wheel (the author of the video is the domowe channel).

Now consider the advantages of EUR systems:

1. The EUR itself is a simple and relatively small system, which saves space in the engine compartment.
2. There are no branch pipes and lines in the EUR systems, which largely contributes to the simplification of the design, respectively, this is reflected in its cost. When using the EUR, the car owner does not need to regularly monitor the level and condition of the working fluid, the same applies to belts.
3. When properly installed, the EUR will save fuel.
4. In addition, the UAZ allows you to customize the system to your preferences, that is, the driver can adjust the effort, as well as the operation of the unit in a certain mode.

Also, the electric steering system has its drawbacks:

1. The main disadvantage of the EUR is its high price. That is why their installation on UAZs is considered inexpedient from an economic point of view.
2. The cost of repairs. Despite the fact that electric amplifiers themselves are quite hardy systems, malfunctions can still occur in their operation over time. If the node fails, the cost of repair will not be cheap, especially since repairing the node at home is more problematic than power steering.
3. The power reserve of electric amplifiers is small. That is why such systems are not installed on SUVs, minibuses, pickups, etc. Accordingly, this is another plus in favor of installing a hydraulic booster on a UAZ.

Description Power Steering

Purpose and design

As you already understood, the main function of the hydraulic booster is to facilitate the steering of a car.

The power steering system itself is a rather complex unit, its main elements are:

1. System pump. This device is used to maintain the required level of pressure in the system, as well as oil circulation. This unit works by means of a belt drive on the crankshaft.
2. Hydraulic cylinder. This component is used directly to facilitate the turning of the wheels under the pressure of the consumable. The device is integrated into the steering system.
3. Switchgear. The purpose of this element is to distribute the flow of the working substance into the required cavity of the hydraulic cylinder.
4. Connecting lines. The pipes circulate oil through the system between the cylinder and the distribution unit, from the expansion tank to the pump, and also from the distributor to the tank.
5. Expansion tank into which consumables are poured. This reservoir is used to store the working fluid. Also, the tank is equipped with a filter element, depending on the system, it can be supplemented with a probe to control the volume.

The principle of operation of the device

The principle of operation of the device is based on the movement of the spool when the driver turns the steering wheel in different directions. When it rotates, the spool itself moves, as a result of which the drain pipes in the system open. When one or another branch pipe opens, the working fluid under pressure begins to move to certain areas of the system. The working substance acts on the piston through pressure, as a result of which it affects the rotation of the wheels of the car.

At the moment when the driver stops turning the steering wheel, the spool stops, which helps the distributor to stop in the neutral position. At this time, the working fluid passes from the discharge hose to the drain, which contributes to the pumping of the substance through the system using a pump (the author of the video is the Demian0805 channel).

Do-it-yourself hydraulic booster installation instructions

The installation of a hydraulic booster on a UAZ is carried out in several stages:

1. First, the second pulley is mounted to install the strap. Attach the device, measure all the necessary distances, after you figure out how to align the pulley, install it and tighten the bolts (you need to use longer ones, because relatives will not). The pulley itself must be pressed onto the existing crankshaft pulley.
2. The next step is to mount the bracket on the power unit. Take the bracket that will mount the UAZ power steering pump and install it in place of the fuel filter, fix all the nuts. There is room for a third mount, but since there is no corresponding hole for fixing, you will have to drill it yourself, for this you will have to dismantle the valve cover. Before drilling, all holes into which metal chips can enter must be closed. After completing these steps, the pump itself is installed on the pulley and bracket, then the strap is put on.
3. If necessary, the steering gear, as well as the fitting head, will need to be sharpened.
4. Then this gearbox is installed on the frame, while all open areas must be painted over. The high pressure line must be fixed in the gearbox, after which this element is removed from the underside of the radiator device and fixed with the help of existing bolts.
5. At the final stage, the expansion tank is installed, all the remaining lines, as well as the system is pumped. The tank is installed in any convenient place, but please note that the lines should not be bent. In addition, the liquid level in the tank must in any case be higher than in the pump. When the lines are installed, the working fluid is poured into the tank, the pumping itself is carried out on suspended wheels.

Power steering on UAZ 469 allows several times to reduce the effort required to turn the steering wheel. This is especially noticeable in off-road conditions, when you have to be in constant tension and actively drive the car.

Justified tuning

Many owners resort to installing a power steering (power steering), as it radically changes the handling characteristics. This process has many technical subtleties that must be taken into account and correctly implemented. Therefore, installation (as well as subsequent possible repairs) should be entrusted to professionals. This revision will take a little time and it is difficult to call it expensive.

Of course, the initial stage will be the inspection of the UAZ 469 for possible obstacles and the selection of a suitable power steering kit.

The installation itself looks like this:

1. Removing the steering wheel, steering column and hinge connecting to the cardan.
2. Disconnecting the rod, which is bolted.
3. Replacing the steering gear and its connection.
4. Installing the hinge, column and steering wheel. In the process, it may be necessary to cut off old fasteners that will no longer be needed - it all depends on how much they interfere. Fastening a new column is carried out in a slightly different way, which should not be embarrassing.
5. Tank and pump installation Power steering on UAZ 469. For operation, the device requires the presence of fluid in the system (the level of which must be constantly monitored during operation).
6. Filling with all-weather gear oil. It is important to achieve complete elimination of air from the system - it has a bad effect on overall performance. Foaming is a bad sign.
7. Checking the interaction of all elements of the hydraulic booster. Often, this stage causes the most problems and takes a lot of time. Do not leave inconsistencies, as they may affect the handling of the machine.

Like the car itself, the unit in question is highly durable and reliable. Repair statistics for it are small, and no special costs are expected in the future. The main cause of breakdowns is increased loads resulting from an unfavorable combination of factors or an excessively harsh driving style.

TO Power steering on UAZ 469 easy enough to get used to. This is the most frequently implemented refinement, which fully justifies itself. All the advantages of this mechanism will be immediately noticeable on rough terrain.
