Adjustment of the steering mechanism is necessary when the vehicle's directional stability is low at high speed
This defect is associated with a violation of the adjustment of the propeller thrust bearings, and in a pair of rack-piston - shaft-sector of the steering mechanism.
After adjusting, the force required to rotate the input shaft should not increase noticeably.
During operation, you should constantly monitor the condition of the hoses, especially high pressure. In case of cracks, swellings and cuts, the hoses must be replaced.
You should also check for leaks of the working fluid (oil) from under the hose clamps, covers of the steering mechanism or the power pump.
When the pressure in the system rises due to the jamming of the bypass valve, it can squeeze out the technological plugs in the pump housing, so you should monitor the system and the quality of the working fluid being filled in, top it up, replace and change the filter in time.
Do not hold the steering wheel in extreme positions for a long time. This can damage or even seize the booster pump.
A slight noise during the operation of the amplifier is not a sign of a malfunction.
Steering screw thrust bearing adjustment
Having removed the steering mechanism together with the bipod, remove the universal joint yoke from the input shaft of the steering mechanism.
We fix the steering mechanism in a vice with the input shaft up, placing the axis of the screw vertically.
In the middle position of the sector shaft with one hand, we swing it by the bipod, and with the fingers of the other hand we check the absence of axial movement (backlash) of the input shaft of the steering mechanism.
If present, adjust the propeller bearings.
To do this, we punch (straighten) the shoulder of the adjusting nut with a beard.
With a special key, turn the adjusting nut clockwise
Compress the bearings.
Tighten the nut carefully, each time checking for axial play on the input shaft.
After the fingers stop feeling the movement of the shaft, we stop tightening.
We lock the adjusting nut with a beard, bending its shoulder into the grooves of the crankcase
The force required to turn the input shaft after adjustment should not increase noticeably.
Adjusting the engagement of a pair of piston-rack - shaft-sector
We remove the steering mechanism from the car along with the bipod (see Removing the mechanism with the GAZ-3110 hydraulic booster).
We install it in a vise in the same way as for adjusting bearings.
If before this operation the bearings of the steering screw were adjusted, then put the cardan joint on the steering shaft and insert the wedge.
Turn the steering shaft to the middle position of the bipod (a little less than two turns of the shaft from any extreme position).
In the middle position of the bipod, slightly turning the input shaft by the cardan, we determine the possible increase in the gap in the engagement piston-rack - shaft-sector.
To adjust the engagement, unscrew the lock nut with a 22 wrench, while holding the adjusting screw with a 6 hex wrench.
Turn the adjusting screw counterclockwise and, at the same time, turn the input shaft by the cardan joint at a small angle, control the engagement gap.
When the gap is no longer felt, tighten the locknut while keeping the adjusting screw from turning.
