To date, in the modifications of the KamAZ car, the most common installation is the reinforced GUR (KamAZ "Euro"). According to the principle of operation and purpose, it is absolutely identical to the hydraulic booster 53212-3400020 installed on the KamAZ-5320. The differences are in the strengthening of the construction of some parts and in changing the mounting of the steering bipod. Tie bolts, nuts, cotter pins have been replaced by nuts with a lock washer.

The durability of the amplifier, as well as any other component or part, directly depends on timely maintenance. During daily maintenance, the condition of the steering wheel drive is checked without any special tools.

During TO-1, the oil level in thetank of the pump GURA 4310-3400020 is checked. If the level is insufficient, then it is necessary to top up the oil to the norm, while the level is checked with the help of the indicator, which is mounted in the plug of the filler neck. At the same time, the frontwheels are installed in a straight position. Before removing the plug, it is necessary to carefully wipe it, as well as the filling neck. There are marks on the pointer, between which there must be a level indicator corresponding to the norm. Oil must be poured only with the help of a funnel with a double mesh through the filling filter, which is located in the neck of the tank. In addition to checking the oil level, lubricate the joints of the steering rods with the help of oil presses until the grease appears in the gaps.

With TO-2, the amount of clearances in the joints of the cardan shaft and steering rods is checked. If necessary, the free movement of the steering wheel should be checked and restored, and the filter should be removed and washed. Freewheeling is determined on an equipped car, without cargo, with the engine turned on and the engine crankshaft speed within the range of 600-1200 revolutions per minute. On new cars, freewheel should not be more than 15°. K-187 or K-402 devices are used for its measurement, while the steering wheel is turned in both directions until the moment when the left front wheel starts to turn. The angle is calculated on the angular scale of the devices from the conditional zero set in the middle of the range of free swing of the steering wheel. If the free stroke exceeds the permissible indicator, the hydraulic system of the amplifier is checked for the presence of air. In addition, it is necessary to check the condition of the hinged rods (steering), adjustment and fastening of the mechanism, tightening of the wedges that fasten the cardan shaft and its clearances. Broken tightenings and adjustments must be restored, and if it is impossible to eliminate gaps in the splines or joints of the cardan shaft, it must be repaired or replaced.

Attention is required before operating the GUR KamAZ:

The filling filter and the filtration element are washed, and in case of significant clogging with resin deposits, they are additionally treated with a special solvent. During seasonal maintenance (in the fall), the oil in the KamAZ-4310 (Euro) GUR system must be completely replaced.

1. Air remaining in the KamAZ power steering system leads to rapid pump failure and damage to parts of the steering mechanism. The presence of air in the system or its ingress is indicated by the foaming of oil in the pump tank, external leaks and grease in the system, and the loud noise of the pump. Also, if after stopping the engine, the oil level in the tank rises by 10 mm or more, there is air left in the hydraulic system of the power steering. In order to avoid pump failure, it is necessary to eliminate the presence of air in the system or eliminate the presence of air in the system.

2. Sealing of the KamAZ power steering system after replacing the steering gear:
a) raise the front wheels of the car so that they come off the ground;
b) pour in the liquid, turn the steering wheel== from edge to edge 20 times and add the liquid again; от края до края 20 раз и опять долить жидкость;
c) start the engine for 2 seconds and turn it off, add fluid;
d) start the engine again for 3-4 seconds. And he will silence the ego, again add liquid (if necessary);
e) start the engine, check the oil level in the tank, turn the steering wheel in one direction and then in the other direction;
e) will lower the front wheels of the car;
g) turn the steering wheel in one direction and release the air from the GUR breather (located under the shaft of the GUR bipod), then turn the steering wheel in the opposite direction to the stop and release the air from the GUR breather again.
The sealing of the KamAZ power steering system is completed, road tests can be carried out.
