29. Remove a lock ring (fig. XIV).

Remove lubricant.

Remove a lock ring.

30. Take out a steering shaft from the case.

31. Take out a gear lath from the case and check a surface.

NOTE If the surface is damaged, for example, furrows were formed, it is necessary to replace the steering mechanism.

32. Take out the old plug of the bearing (fig. XV).

Release the bearing 1 plug by means of the suitable tool 2.

Push out the bearing plug from the case from the opposite side by means of the long tool.

33. Clear a nest for the bearing.

34. Install the new plug of the bearing (fig. XVI).

Insert the bearing plug against the stop.

Establish a lock ring 1.

35. To slightly grease the plug of the bearing with the applied lubricant.

36. Establish a gear lath.

Evenly grease a gear lath with the applied lubricant.

Insert a gear lath into the center of the case.

37. Establish a steering shaft.

NOTE The gear lath has to be established in average situation.

Marks in the helmsman to a shaft and the case have to coincide (see fig. XI).

Measure a vystupaniye of both ends of a steering rack concerning the case by means of a caliper.

NOTE The size has to be identical on both sides.

If the vystupaniye is not identical, repeat operation for obtaining the required result.
