20. Replace any worn or broken parts.

B.  Basic Unit Assembly

1.  If clutch is manual reset, install the reset 

screw from the inside of the housing turning 

counterclockwise until the reset screw pin stops 

the screw from turning.

2.  Press the rotor (12) into the housing bearing. 

If the rotor is a Model FJ or Model FG, press 

the shorter end of the rotor into the housing 

bearing. If the rotor is a Style 2, then press the 

sawcut section of the rotor into the housing 

bearing.
