4. Position the center pulley puller on the end of the drive shaft,
and remove the pulley assembly using any commercially avail-
able pulley puller.
To prevent the pulley groove from being deformed, the puller
claws should be positioned into the edge of the pulley assembly.
5. Remove the field coil harness clip using a pair of pliers.
6. Remove the snap ring using external snap ring pliers.
Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check the appearance of the pulley assembly. If the contact surface
of pulley sows signs of excessive grooving, replace clutch disc and
pulley. The contact surfaces of the pulley assembly should be
cleaned with a suitable solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.
INSTALLATION
1. Install the field coil.
