Removing the steering gear for replacement or repair
We install the car on a viewing ditch or lift
Drain the fluid from the system
Unscrew the head on the 22 bolt fitting of the discharge hose
Remove two copper washers from the bolt
Unpin the wedge nut with pliers
Unscrew the 13 nut with a wrench
We knock out a wedge with a hammer through a soft metal drift
Leaning with a large screwdriver or a mounting spatula on the engine mount brackets, pry off the hinge fork and remove it from the steering shaft
Disconnect the steering rod from the bipod of the steering mechanism
We unscrew the three bolts securing the steering mechanism to the frame side member with a 17 head
Remove the steering gear from the car
We unscrew the bolt fitting of the outlet hose with a 22 wrench and remove two copper washers from the bolt
Unscrew the injection hose extension with a 22 wrench
There is a copper washer between the extension and the steering gear
To remove the bipod, unscrew the bipod nut with a 30 head
We mark with a chisel the relative position of the bipod and the steering shaft
We press the bipod from the shaft with a puller
Install the steering gear in reverse order, replacing the copper washers
Power steering adjustment
We remove the steering mechanism, as described above, without removing the bipod and extension of the inlet hose
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. For this:
Through a drift, we straighten the collar of the adjusting nut, which has been punched 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 kgf.m
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
Bending the collar of the nut into the groove with a beard
We swing the bipod of the steering mechanism by hand
If there is a gap, adjust the gearing
To do this, remove the bipod from the sector shaft
Use a screwdriver or a knife blade to pry off and remove the top and bottom protective covers
We unscrew the 13 lock nuts of the lock bolts with a wrench
Using a 12 wrench, unscrew the locking bolts by 2-3 turns
With a special key, we turn the adjusting eccentric cages of the sector shaft bearings
When adjusting, the possibility of misalignment 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
