Attention! We carry out the work on an inspection pit or lift.
We remove the bolt securing the fork of the lower cardan joint of the intermediate shaft of the steering gear to the shaft of the worm of the steering gear (see Removal the steering column).
We hang up and remove the left wheel.
We press out the ball pins of the rods from the holes of the knuckle: middle (see Removal the middle rod) and lateral (see Removal the side traction).
We move the rods down.
Using a 17 mm socket, unscrew the nut securing the steering gear housing to the left side member,…
...holding the bolt from turning with a wrench of the same size.
We take out the bolt.
Similarly, unscrew and remove the other two bolts securing the steering gear housing.
We remove the steering mechanism.
A rubber sealing sleeve is inserted into the hole in the front shield through which the worm shaft passes.
The clearance in the worm bearings is determined by the change in distance…
…between the end of the steering gear housing…
…and a mark on the worm shaft…
…when turning the shaft in different directions.
To adjust the clearance in the worm bearings, we clamp the crankcase in a vice..
…and using a 13 mm wrench, unscrew the four bolts securing the bottom cover.
We remove the lid..
…and adjusting shims.
We reduce the gap in the worm bearings by removing the gasket or replacing it with a thinner one.
We install the steering gear in the reverse order, without fully tightening the nuts of the crankcase mounting bolts. We secure the steering rods and the intermediate shaft of the steering control. The assistant turns the steering wheel two or three times to the right and left until it stops. At the same time, we check the self-installation of the steering control units in their regular places. We tighten the nuts of the crankcase mounting bolts completely.
