1. A gap of 0.1–0.5 mm is set between the pusher and the master cylinder piston (see fig. Clutch pedal and master cylinder). This gap, necessary for the complete disengagement of the clutch, is regulated by the limiter 14 of the clutch pedal. The gap is determined by the free play of the pedal, equal to 0.4–2 mm.
2. The free travel of the pusher of the clutch release fork, equal to 4–5 mm, is regulated by the nut 5 (see fig. Slave cylinder and clutch release fork), which is fixed with a lock nut 6.
3. The amount of free travel of the pusher is controlled by a special template.
4. After making the above adjustments, the clutch pedal free play before the clutch is disengaged should be 25–35 mm.
