UAZ -374195 Operation Manual page 85

If a radial air gap in the joint of the steering shaft is detected (axial
displacement of the crosspiece in bearings), punch the bearings in yoke
eyes, so that the bearing sleeve is not deformed.
Replace the steering column propeller shaft, if air gaps in the spline
couplings are detected.
If air gaps in the steering mechanism are detected, adjust the mechanism
at UAZ service station.
Hydraulic Power Steering. When turning the steering wheels to the
right or to the left up to the stop the noise in the hydraulic power steering
may occur as a result of the maximum pressure in the hydraulic pump.
This noise is a typical sign of the pump work and it does not influence
the efficiency of the steering system.
The steering mechanism can be used only for a short time when the
hydraulic power steering is broken as a result of the pump damage, the
hose or the pump drive belt malfunction or when the vehicle is towed
after the engine stops. If the power steering system lacks oil, the pump
drive belt shall be removed, otherwise the pump seizure or the belt rip
is possible. Pay special attention to coolant temperature when the pump
drive belt is removed to avoid engine overheating.
long-term vehicle operation with the disabled power steering
can lead to the premature wear of the steering system.
Tightening of the power steering pump drive belt (Fig. 9.5) consists
in moving the pump along the bracket, mounted to the engine. loosen the
pump bolts mounted to the bracket, move the pump with the tightening
screw, until the belt is properly tightened, and screw the pump bolts.
Replace the belt if damages or excessive stretch are detected.
Hydraulic power steering oil: level check and change. To check the
oil level in oil tank 3 (Fig. 9.26) place the front wheels straight. Pour the
oil into the oil tank up to the level of the filling strainer screen. Beforehand
run the oil through the filter with the maximum pour size of 40 μm.
Fill the system as follows:
1. Disconnect the drag link from the drop arm and lift the front
wheels with a jack.
2. Uncap the oil tank, pour oil up to the filter screen.
3. Do not start the engine and turn the steering wheel or the input
shaft lock-to-lock until air bubbles stop coming out of the oil tank. Add
some more oil into the tank.
4. Start the engine and add the oil into the tank simultaneously.
