10.19. Checks and adjustments of a steering wheel
|
|
- Bring forward wheels of the car into rectilinear situation and make measurement of size of a free wheeling (люфта) a steering wheel. If the result of measurement exceeds the maximum admissible value makes (35 mm), check durability of a joint and estimate degree of wear of components of a steering column, the steering mechanism, a steering drive and a forward suspension bracket.

Centering
|
|
- For check of correctness of centering of landing of a steering wheel on a shaft of a steering column bring forward wheels into rectilinear situation.
- Corners of installation of forward wheels should be adjusted correctly (see. Corners of installation of forward wheels), the lath of steering transfer should occupy the central situation.
- At performance of all listed above conditions of a spoke of a steering wheel should settle down strictly horizontally, and wheel deployment against the stop in any direction to be made for identical quantity of turns.
- In case of need remove a steering wheel (see. Removal and installation of a steering wheel) also modify its situation on a shaft.
- If to achieve demanded result by reinstallation of a steering wheel it is not possible (the central situation it appears in the middle between shlitsa of a shaft, release lock-nuts of tips of steering drafts and correct position of the last, having displaced each of two on identical quantity of rounds of a carving in the corresponding direction.

Resistance to rotation
|
|
- Park the car on an equal horizontal platform with a firm covering.
- Check correctness of a rating of tires.
- Cock the parking brake, then start the engine on single turns and wait GUR hydraulic liquid warming up to temperature about 60 — 80°С.
|
- Hook for a spoke of a steering wheel on a dynamometer of bezmenny type.
|
|
- Measure size of a torque of rotation of a steering wheel at deployment it under 360 ° from neutral situation. If the result of measurement exceeds the maximum admissible value (4.1 kgfs), check effort of sliding of a lath of the steering mechanism for check of a condition of its internal components (see. Check of effort of resistance to sliding of a lath of the steering mechanism).
