10.21. Adjustment of a torque of a provorachivaniye of a leading gear wheel of the steering mechanism
|
|
- Remove assembly of the steering mechanism from the car (see. Removal and installation of assembly of the steering mechanism) also clamp it in a vice with soft sponges.
- Disconnect from a case of reechny transfer hydraulic lines and merge working liquid.
- Bring the steering mechanism into neutral situation and make basic marking.
- Turn out the adjusting screw, grease its carving part with fixing hermetic, then screw the screw on a place and slightly tighten a lock-nut.
- By means of a dinamometrichesky key tighten the adjusting screw with effort 4.9 — 5.9 Nanometers, then again weaken it and again tighten — this time with effort of 0.2 Nanometers.
- Connect to a dinamometrichesky key a special nozzle (KV48100700).
|
- Several times displace a lath for all length of its course, then make measurement of a torque of a provorachivaniye of a shaft of a leading gear wheel of the steering mechanism on a corner 180 ° from neutral situation — consider the maximum registered indication and fix a shaft in this situation.
|
|
- Release the adjusting screw and again tighten it with effort
4.9 — 5.9 Nanometers, having weakened then on a corner 10 — 20 °.
- Tighten with demanded effort a lock-nut.
- Repeat torque measurement, turning the steering mechanism from an emphasis against the stop. Write down the maximum and average indication of a dynamometer. Average value should make 0.8 — 1.5 Nanometers, maximum — 0.6 Nanometers.
- If any of results falls outside the limits an admissible range, check effort of sliding of a lath (see. Check of effort of resistance to sliding of a lath of the steering mechanism) — in case of need repeat adjustment, or replace the steering mechanism.
