2. In a motor compartment turn away bolts of the coupling and shift it from the steering mechanism.
3. Set the parking brake, hang the front of the car.
4. Unsplint and turn away nuts of fastening of longitudinal steering draft and a tip of cross steering draft to a bipod of the steering mechanism.
5. Disconnect, using a puller, the longitudinal traction from the bipod.
6. Check (paint) the relative position of the bipod and the shaft of the steering mechanism. Using a puller, disconnect the bipod self-locking nuts from the steering gear and remove the bipod.
7. Turn away bolts of fastening and remove from below the steering mechanism.
8. Wash the steering gear (kerosene) and dry it.
9. Loosen the lock nut and cover bolts, then turn the adjusting screw clockwise while removing the cover and gasket at the same time. Remove the bipod shaft.
10. Remove the snap ring, unscrew the round nut and adjusting ring and remove them. If necessary, use a spanner.
11. Remove the entire steering gear assembly consisting of the worm, nut and ball drive.
12. Using a puller, press the outer ring of the bearing out of the steering gear housing.
13. Remove the gland.
14. Remove the bearing inner races from the worm shaft. If these bearings are to be reused, lightly press them together with the outer races; do not swap them during installation.
15. Clean and inspect parts for wear and damage. Knot «worm / nut / balls» replaced as an assembly.
16. At the beginning of the assembly, press the outer race of the upper bearing into the adjusting ring.
17. Heat the bearing inner races to 80°C in hot oil and install them on the worm.
18. Install the ball cage into the lower bearing outer race.
19. Install worm and nut.
20. Install a new oil seal on the adjusting ring.
21. Install the upper ball bearing cage onto the worm.
22. Using a piece of thin-walled plastic pipe as a mandrel, install it on the worm shaft to protect the edges of the stuffing box, slide the adjusting ring into place and tighten it a few turns.
23. Remove the mandrel and tighten the adjusting ring so that the worm turns with difficulty.
24. Lubricate the ring nut threads with threadlocker and screw the ring into the crankcase.
25. Adjust the steering gear worm. Why tighten the adjusting ring with a pin wrench so as to select the axial play and ensure easy rotation of the worm. Without changing the position of the adjusting ring, fully tighten the ring nut. Install the snap ring.
26. Install the adjusting screw, spacer and retaining ring in the recess on the end of the gear sector shaft. The play between the head of the adjusting screw and the undercut of the shaft must be eliminated by selecting a washer.
27. Install the gear sector shaft in the steering gear case so that the sector's central tooth enters the worm's central cavity.
28. Install a new gasket under the steering gear housing flange; install the top cover, adjusting screw into the opening of the cover. Install and, turning, tighten the bolts securing the cover.
29. Thread the lock nut onto the adjusting screw, but do not tighten it.
30. Put a protective cover on the splines of the sector shaft (can be wrapped with tape) and press the stuffing box onto the shaft using a metal pipe mandrel.
31. Fill the steering gear with oil.
32. Set the middle position of the steering mechanism, the center point of the worm is visible in the center of the filler hole (hole). Adjust the axial play of the gear sector shaft.
33. Wind the cord around the splined end of the sector shaft and tie a dynamometer to it. Measure the force required to rotate the shaft of the gear sector about its middle position. This force should be 5.0-7.0 kgf. By turning the adjusting screw, achieve this value, without changing the adjustment, tighten the lock nut (locknut).
34. Install the fill plug.
35. Install in the reverse order of removal. Pay attention to effort (moment) tightening nuts and bolts. Make sure that when turning the steering to the extreme position, the bipod or pendulum arm reaches the stops on the frame cross member. If it doesn't, adjust the tie rod length.
