Adjustment of the steering mechanism is needed when the car's directional stability is low at high speed (you don't feel the steering wheel 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, swelling 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.

Adjustment

Remove the steering mechanism without removing the bipod.

We clamp the mechanism in a vice with the fittings down and drain the remaining oil into the container, turning the shaft of the mechanism with a key by 17.

Having pressed the spool shaft with your hand, we swing the bipod.

If at the same time axial play of the shaft is felt, adjust the thrust bearings.

To do this, we straighten the collar of the adjusting nut through the beard or drift, which is sharpened into the grooves of the crankcase.

With a special wrench, turn the nut clockwise until the gap is eliminated.

At the same time, we control the moment of rotation of the shaft, which should be no more than 0.2 kgcm.

To do this, with a dynamometer hooked to the key at 17, we measure the moment of turning the spool shaft.

With a lever length of 200 mm, the force should not exceed 1.0 kgf.

We swing the bipod of the steering mechanism with our hand.

If there is a gap, adjust the gearing

To do this, remove the bipod from the sector shaft.

To remove the bipod, unscrew the bipod nut

With a chisel we mark the mutual position of the bipod and the steering shaft

Use a 13 key to unscrew the lock nuts of the locking screws

With a 12 key, we unscrew the locking bolts by 2 - 3 turns

With a special key, we turn the adjusting eccentric cages of the bearings of the sector shaft

When adjusting, the possibility of skew of the sector shaft should be excluded, therefore, we turn the clips one by one at a small angle until the gaps in the engagement are eliminated.

Install the steering gear in reverse order.
