You will need: keys «on 7», «at 12», «at 13» (two), ruler.
1. To measure the full travel of the clutch pedal, measure the distance from the pedal pad to the floor without depressing the pedal.
2. Press the pedal all the way down and repeat the measurement. The difference between the two measurements is the total clutch pedal travel, which should be nominally 120-125mm. Adjustment of the full stroke of the pedal in operation is not provided. Significant travel deviation from the specified values, accompanied by abnormal clutch operation (it «slips», «leads», jerks appear at the moment of starting off), indicates damage to the clutch or drive to turn it off. With minor deviations from the specified values, but with proper operation, the clutch can continue to be used.
3. In order to determine the free play of the clutch pedal, measure the distance from the initial position of the pedal to the position in which an increase in resistance is felt when pressing the pedal with your hand. The nominal free travel of the clutch pedal is 10-12 mm. If the free play differs from the nominal, adjust the length of the pusher of the clutch master cylinder, for which...

6. Check up the moment of inclusion of coupling at pedal release. With the engine idling, press the pedal all the way down, engage first gear and slowly release the pedal, trying to determine at what distance the pedal pad from the floor the car starts to move. If the clutch and its release drive are in a normal state, this distance should be 30-40 mm. If the pedal travel before engaging the clutch is less than or greater than the specified value, check the following:
- clutch pedal free travel. Adjust if necessary;
- full pedal travel. If the stroke is less than permissible, adjust it and check the condition of the clutch release drive;
- the presence of air in the clutch release hydraulic actuator. If necessary, pump the hydraulic drive;
- the condition of the clutch pressure and driven discs. If necessary, replace defective units and parts.
