4.3 Clutch Adjustment and Maintenance
4.3.1 Clutch and Operation System Adjustment
During clutch operation, owing to the wear of clutch friction discs and clutch plates, the clearance between the
clutch plate and the clutch fingers will gradually decrease. (Normal clearance is 2–2.5 mm.). Sometimes the
clutch fingers may contact the throwout bearing, eliminating clutch pedal free play, and the clutch will slip and
the throwout bearing will stick. In this situation the clutch should be checked and adjusted.
4.3.1.1 Clutch Pedal Free Play Adjustment
Unfasten the lock nut (1) counterclockwise and rotate
the clutch. The clutch pedal free travel is adjusted by
the vertical rod assembly (2) and should be 35–40 mm.
Make the clearance between the clutch fingers and
the throwout bearing 2–2.5 mm., then lock the nut (1) tight.
