4.2 Clutch Adjustment and Maintenance   

4.2.1 Clutch and Operation System Adjustment

   

During  clutch  operation,  in  reference  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. 

4.2.1.1 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.
