Loosen the master cylinder bolts on the pedal bracket. Pay attention to the position of the limit stop on the master cylinder. Leave the pusher on the clutch pedal.
Installation of the master cylinder is carried out in reverse order. Before mounting the master cylinder, install a pusher in it. Put a hose on the rubber tip of the master cylinder and connect it to the combination tank. Check and, if necessary, adjust the gap between the clutch pedal pusher and the master cylinder piston. Bleed the clutch hydraulic system. This work is described below.
Check the operation of the clutch release actuator. To do this, press the clutch pedal and engage reverse gear. A scraping sound when shifting gears indicates that the clutch is not fully disengaged. It is necessary to check the operation of the entire mechanism.
If the clutch pedal does not reach the stop when pressed, this may lead to incomplete disengagement of the clutch.
