- a gap of 0.1-0.5 mm is set between the pusher and the master cylinder piston (see fig. 3-2). This gap, necessary for the complete disengagement of the clutch, is regulated by the limiter 5 of the clutch pedal. The gap is determined by the free play of the pedal, equal to 0.4-2 mm;
- free play of the pusher of the clutch release fork equal to 4-5 mm, regulated by nut 5 (pic. 3-3), which is fixed with a lock nut 6. The value of the free travel of the pusher is controlled by a special template.
After making the above adjustments, the clutch pedal free play, before the clutch is disengaged, should be 25-35 mm.
