5.2.2.3. Check of effort on a steering wheelCheck the following:
– dimension of tires and pressure in tires;
– liquid level in a tank of the hydraulic booster;
– tension of a belt of the drive of the pump of the hydraulic booster.
Install the car on a firm horizontal surface, establish wheels in provision of the rectilinear movement.
Remove the module of an inflatable safety cushion.
ATTENTION
Be careful at dismantle of the module.
|
Start the engine and warm up working liquid of the hydraulic booster of steering to 50–60 °C.

Fig. 5.9. Measurement of effort on a steering wheel
|
Measure effort on a steering wheel by means of a dynamometer key (fig. 5.9).
If the effort does not meet standard, check the following:
– availability of air in a hydraulic system of the amplifier of steering;
– leaks through hoses and their connections;
– operation of the pump of the hydraulic booster and steering mechanism.
Effort on a steering wheel of 7,8 N · m.
NOTE
For check of effort on a steering wheel compare it by effort on a steering wheel of other car of the same model under the same conditions.
|
The effort on a steering wheel depends on the following conditions:
– condition of a paving (dry or damp, asphalt or concrete);
– a condition of tires (the producer, wear degree, pressure in tires).
