Adjust dowel to have a little space 
between pad and clutch when you 
try to open it.  
It’s the same for the other

 

Mount clutch on crankshaft without 
forcing a lot.

 

Reassemble washer and nut.

 

If you need to tune up clutch, it is 
possible to adjust dowels by a wrench 
in carter’s holes without unmounting 
clutch. 

 

      NOTE: 

Tightening dowels, you have a smaller opening of pads, releasing them, you have a 

faster contact of pads on bell housing.
