Steering wheel UAZ Bukhanka - malfunctions and causes

4 / 5 ( 1 voice )

The new UAZ Bukhanka is equipped with power steering, which makes operating the bus much more comfortable. However, many owners of this model own older buses that do not have this option.

However, owners of both modifications often encounter breakdowns of the UAZ Bukhanka steering wheel, and therefore it is worth considering the most common malfunctions and the causes of their occurrence. To know what to pay attention to first. As for repairs, it can be carried out at the STOGUR station, which specializes in such problems. Their portal is https://sto-gur.ru/

Excessive free play

This problem is evident when the free play of the Bukhanka steering wheel exceeds 40 mm, provided that it is measured directly on the rim of the steering wheel.

Causes

The bolts securing the crankcase to the spar bracket have become loose.
The bipod fixation nut is not tightened sufficiently.
Failure of adjustment or excessive wear of the worm bearing tightening elements.
Failure of adjustment or excessive wear of the engagement elements of the rollers and worm.
Weak tightening of ball pin cones.
Weak fixation of the steering knuckle arms.
Excessive clearances in steering linkage joints.
Excessive gaps in the sealing of the ends of the springs (front chassis).

Steering column switches

For the convenience of performing certain manipulations, the car has special switches that are located under the steering wheel.

The steering column switches of the UAZ Patriot have a design consisting of two switches, in the form of a pair of plastic levers located under the steering column. The device located on the left side is responsible for:

The work of the right turn signal;
Operation of the left turn signal;
Turning high and low beam on and off;
Possibility of flashing high beams.

Movement (radial) of the steering shaft

This UAZ Bukhanka steering problem occurs when movement begins to be transmitted directly to the steering wheel.
Causes

Insufficient tightening of the steering column stepladder fixing nuts or weak fixation of the steering column bracket to the instrument panel.
Excessive wear or destruction of the steering column bearing.

Why do you need to adjust the UAZ Patriot steering gear?

The most common steering failures on a Patriot are related to the power steering or gearbox.

Signs of trouble:

squeaks and extraneous sounds are heard when turning the steering wheel;
jamming while turning the steering wheel;
uneven wheel rotation;
play relative to the center position of the steering wheel.

Adjusting the gearbox will help cope with these problems. If the faults remain, then the power steering needs to be replaced.

Power steering or electric power steering on a UAZ: which is better?

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

Regarding the disadvantages of power steering:

If you install power steering on a UAZ, 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.
You must always follow the rules for using the system to prevent its failure.
The operation of the unit should always be monitored 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 order - leaks or cracks are not allowed. If problems arise in the operation of the unit, this is fraught with repair of the power steering.
The functioning of the power steering largely depends on how the power unit operates. 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 let's look at the advantages of EUR systems:

The EUR itself is a simple and relatively small system, which saves space in the engine compartment.
ESD systems do not have pipes or lines, which greatly simplifies the design; accordingly, this is reflected in its cost. When using an electric power steering system, the car owner no longer needs to regularly monitor the level and condition of the working fluid; the same goes for belts.
If installed correctly, the EUR will save fuel.
In addition, the electric power steering on the UAZ allows you to customize the system to suit your preferences, that is, the driver can adjust the force, as well as the operation of the unit in a certain mode.

Also, the electric steering system has its disadvantages:

The main disadvantage of the EUR is its high price. That is why their installation on UAZ vehicles is considered inappropriate from an economic point of view.
High cost of repairs. Despite the fact that electric amplifiers themselves are quite durable systems, malfunctions can still occur in their operation over time. If the unit fails, the cost of repair will not be cheap, especially since repairing the unit at home is more problematic than power steering.
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 the UAZ.

DIY installation instructions for power steering

Before installation, prepare the installation kit, the procedure is described briefly:

First you need to dismantle the steering bipod and then bend it. To do this, the bipod must be heated; to prevent deformation, the cone along with the spline must be installed with the inserts inward.
Then a bracket for the transverse rod is made, it can be made from a sawn-off shank from a GAZ 66 car, the most optimal option since the internal diameter is the same. The bracket should not be completely welded; it is best to make the seam along the rod itself, this will increase the strength.
The next step is to install the power steering cylinder. For installation you will need a special bracket; you can purchase it or make it yourself.
The bracket itself will need to be welded, or entirely.
Further installation of the cylinder on the bracket is carried out in the same plane as the bridge.
The hydraulic cylinder rod should be set to the middle position when the vehicle wheels are straight. By doing this, you can determine where to install the tie rod clamp. Then this element also needs to be welded.
The unit is being assembled. A reservoir for working fluid is installed, and all hoses necessary for normal operation are connected. The tank must be installed in a convenient place, but remember that the hoses should not be bent in any case. After assembling the system, you need to pour oil into the reservoir.
Then the front part of the car is jacked up, the steering wheel needs to be turned in different directions, holding the steering wheels in extreme positions. The engine starts, the procedure is repeated - this way you can pump the liquid through the pipes.

Steering of the UAZ Hunter with power steering, principle of operation, failure of the power steering

The UAZ Hunter steering system consists of a power steering mechanism, a steering column with a steering and propeller shaft, a steering wheel and a steering gear which includes two tie rods connected by ball joints to the steering knuckles of the front suspension.

The steering wheel is mounted on the splines of the steering column shaft and attached to the shaft with a nut. The steering shaft is mounted in the steering column tube on two bearings and transmits torque from the steering wheel to the steering mechanism through a driveshaft consisting of a splined shaft, a sliding fork and universal joints.

The steering gear is of the screw-ball nut-sector type, installed in the engine compartment, the steering gear housing is bolted to the frame. The connections between the hoses and the steering mechanism are sealed with copper washers. The power steering reservoir is installed in the engine compartment on the left mudguard bracket and is connected by a hose to the power steering pump and to the hydraulic fluid return line.

Plus, at the customer’s request, the steering wheel must be left at the same height.

To do this, I sawed the steering shaft and ultimately extended it through a piece of smooth reinforcement along the inner diameter of the shaft pipe. And in the area where the shaft connects to the gearbox, I welded a cardan. This made it possible to compensate for the changed shaft angle due to the body lift.

One of the disadvantages of this approach is that the opportunity to run the biblika wire inside the shaft pipe is lost... But. Art requires sacrifice!

To install the power steering, a power steering pump from Patriot brand “ZF” and a five-groove pulley were purchased. The belts on the ZMZ-409 are five-strand. High pressure hoses were manufactured in a specialized office. We purchased a bracket for the power steering pump. And a belt was selected, which was 1119 mm long.

We throw out the tension roller and put the power steering bracket in its place.

But even here there are some surprises. Do you see the top bracket bolt? But it won’t get out completely unless you remove the pulley...

Then we install the power steering bracket for the pump.

In principle, the pump can already be installed. But for now we don’t have space to install a power steering reservoir.

I found a great place for it, but to install it there it was necessary to make a new mount. I made it from a 2mm strip of metal. Painted it with auto enamel.

As a result, the tank fell into place and access to it is convenient and not difficult.

Next, we simply connect the line with the hydraulic cylinder, power steering pump and spool valve.

All. All that remains is to fill in dextron and bleed the system of air. The power steering from GAZ-66 is installed on the loaf and works.

DIY installation instructions for power steering

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

First, the second pulley is installed to install the strap. Attach the device, measure all the necessary distances, after you understand how to align the pulley, install it and tighten the bolts (you need to use longer ones, since your family won’t). The pulley itself must be pressed onto the existing crankshaft pulley.
The next step is to install the bracket on the power unit. Take the bracket that will secure the UAZ power steering pump and install it in the place where the fuel filter is mounted, secure all the nuts. There is still room for a third fastening, but since there is no corresponding hole for fixing, you will have to drill it yourself, and for this you will have to remove the valve cover. Before drilling, all holes into which metal shavings 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.
If necessary, the steering gearbox, as well as the fitting head, will need to be sharpened.
Then this gearbox is installed on the frame, and 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 bottom side of the radiator device and fixed using the existing bolts.
At the final stage, the expansion tank and all remaining lines are installed, as well as the system is pumped. The tank can be installed in any convenient place, but keep in mind that the lines should not be bent. In addition, the liquid level in the tank should in any case be higher than in the pump. When the lines are installed, the working fluid is poured into the tank, and the pumping itself is carried out on suspended wheels.

Hydraulic boosters: mounted on UAZ “loaf”

Classic – UAZ “loaf”

Examples have been given more than once when the most difficult tasks in Russian regions were handled exclusively by vehicles of the UAZ 452 type. It’s not every day that you can use a heavy-duty URAL or an expensive foreign-made SUV. But for UAZ, the issue of modernizing the existing design is relevant. Because, despite the excellent maneuverability, the ease of control for the driver is not always at the desired level.

One of the elements that makes driving this off-road van much easier is the power steering (power steering). The use of hydraulic booster on the UAZ “loaf” began relatively recently. But before you start tuning, you need to remember the structure of the standard factory steering design.

Examination

With the engine warm and running, turn the steering wheel from side to side. In the first seconds, excess air should come out of the tank. If it starts to foam, it means the system is leaking and you need to look for a breakdown. After thoroughly sealing all the hoses, start the engine and check the operation of the amplifier again. The power steering installed on the UAZ “Bukhanka” from a foreign car should operate smoothly and silently. The belt does not whistle, there are no leaks of working fluid.

Adjusting the steering column of a UAZ Hunter with power steering

The steering linkage consists of a bipod, a steering bipod rod and a steering linkage rod, adjustable in length, tie rod ends, which have different thread directions depending on the installation side, a steering knuckle lever, steering knuckles and ball pins.

Steering UAZ Hunter with power steering, principle of operation

When the steering wheel rotates, the steering mechanism screw is screwed in or out of the piston nut, which, in turn, moves along with the spool. The fluid pressure in one of the cavities of the steering mechanism increases - the piston nut moves. Moving, the piston nut turns the shaft of the steering bipod, which, in turn, turns the steered wheels through the steering linkage rods. The working fluid, having passed through the steering mechanism, returns to the power steering reservoir through the outlet hose.

In power steering, the pressure of the working fluid is created by a vane-type pump mounted on the engine bracket. The pump is driven by a V-belt from the engine crankshaft pulley. A flow safety valve installed in the pump maintains the required pressure of the working fluid in the power steering system depending on the engine speed.

Noise in the power steering system of the UAZ Hunter

When turning the front wheels to the right or left all the way, noise or a hum may appear in the power steering system, which occurs due to the power steering pump reaching maximum pressure. Such noise or hum is a characteristic sign of pump operation and does not affect the performance of the steering as a whole.

Steering mechanisms of UAZ Hunter with hydraulic booster

The steering of the UAZ Hunter, depending on the configuration of the car and its year of manufacture, could be equipped with steering mechanisms screw - ball nut - sector with hydraulic booster, manufactured by INMASH, Sterlitamak or BZAGU, Borisov, of two types, differing in the type of distributor: shaft-spool or shaft -rotor.

On vehicles with steering gear 31519-3400011-10, the cardan joint is attached to the steering gear shaft with a bolt, and on steering gear 31519-3400011-20: with a wedge with a washer and nut.

Power steering failure on UAZ Hunter

If the hydraulic booster fails, the ability to drive the car remains, but the force on the steering wheel increases noticeably. If there is no oil in the power steering system due to damage to the pump or destruction of the hoses, it is necessary to remove the drive belt, otherwise the power steering pump may jam and the belt may break.

When the pump drive belt is removed on a UAZ Hunter with a ZMZ-409 engine, it is necessary to control the coolant temperature, since overheating of the engine is quite possible. Long-term operation of a vehicle with a non-working power steering leads to premature wear of the steering mechanism parts.

Inspection and testing of the UAZ Hunter steering mechanism with power steering

Presented in a separate material.

Maintenance of the UAZ Hunter steering mechanism with power steering

It consists of checking the tension of the power steering pump drive belt, checking the tightness of the hoses and their connections, checking for leaks in the seals of the pump and steering mechanism, checking the level and replacing the working fluid in the power steering reservoir.

The power steering fluid must meet Dexron IID specifications. The process of replacing the working fluid and filter in the power steering reservoir, as well as the tension parameters of the power steering pump drive belt on the UAZ Hunter, is described in more detail in a separate material.

Repair of power steering shnkf 453461130 for UAZ 469

Problem: the power steering gearbox leaked, it started dripping, and then it started leaking like a bucket, I bought a repair kit for cuffs and decided to repair it.

I unscrewed all the bolts and all the connections and here he is on the ground

Patient. On the operating table, see what the autopsy reveals

To begin with, it was necessary to remove the bipod from the shaft; I had to make an improvised puller.

Disassembly is simple: unscrew two bolts with locknuts that secure the covers, remove the retaining rings of the covers and, using a hammer, begin to knock out the covers by hitting the shaft

Be careful, when they come out, a bunch of rollers will fall out, it is important not to lose them - these are shaft bearings

Here are the covers removed, we see inside a seal of three cuffs: two plastic, black and white, and a rubber ring between them

Here they are dismantled

Removed shaft and cover seals

I replaced the cuffs and looking at the covers I saw that their holes were not in the center and realized that by turning them the backlash in the worm joint of the gearbox was adjusted.

Next, I disassembled the drive shaft cover (shaft on the steering wheel). There I replaced the oil seal and rubber rings in the cover. The main thing is not to unscrew the shaft from the piston, otherwise you will have problems for an hour. There are balls inside, which are difficult to put back in place later.

Steering shaft cover with oil seal

When disassembling, I saw why the leak started, due to the fact that the cover was not secured and the ingress of dirt and water caused corrosion and risks on the shaft, in short, it’s an ass, I don’t know if new cuffs will help

Without thinking for a long time, I decided to make a protective cap against dirt and, if I’m lucky, against oil leaks if that happens over time. To do this, I drilled two holes and cut threads for screws.

Here's the lid itself

I assembled everything, adjusted all the gaps, by eye of course, and put it in place. No leaks yet. The autopsy had almost no effect on the work of the GUR. Only by ear it seems to be buzzing less, but that’s how it is by ear. Operation will show.

Installation of ADS-Yubei power steering kit for UAZ 469

This procedure is perhaps the most long-awaited, because... I wanted comfortable steering. All those gearboxes that were in the past either played terribly, or crunched and turned the wheels very tightly. I settled on this set thanks to reviews on the internet. Among the Borisov and Sterlitomakovsky ones, you won’t find adequate and more or less reliable ones during the day, and ready-made kits cost over 32 kilorubles in our region. What was required for installation: 1) The kit itself; 21500 rub.
