10:21. Adjustment of torque of a provorachivaniye of the 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) and clamp it in a vice with soft sponges.
- Disconnect hydraulic lines from a case of rack transfer 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 the fixing sealant, then screw the screw into place and slightly tighten a lock-nut.
- By means of a dynamometer key tighten the adjusting screw with effort of 4.9 — 5.9 Nanometers, then again weaken it and again tighten — this time with effort of 0.2 Nanometers.
- Connect a special nozzle (KV48100700) to a dynamometer key.
|
- Several times displace a lath at all length of its course, then perform measurement of torque of a provorachivaniye of a shaft of the leading gear wheel of the steering mechanism on a corner 180 ° from neutral situation — consider the maximum registered indication and record a shaft in this situation.
|
|
- Release the adjusting screw and again tighten it with effort
of 4.9 — 5.9 Nanometers, having weakened then on a corner 10 — 20 °.
- Tighten a lock-nut with the required effort.
- Repeat measurement of torque, turning the steering mechanism from an emphasis against the stop. Write down the maximum and average indication of a dynamometer. Average value has to make 0.8 — 1.5 Nanometers, maximum — 0.6 Nanometers.
- If any of results exceeds the limit of 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.
