7. After removing drive plate, remove shims from either drive shaft
or drive plate.
8. Remove snap ring using external snap ring pliers.
9. Remove pulley assembly with puller using a commercially avail-
able pulley puller. (Position center of puller on end of drive
shaft.)
For pressed pulleys:
To prevent deformation of pulley groove, puller claws should be
hooked under (not into) pulley groove.
For machine lathed pulleys:
Align pulley puller groove with pulley groove, and then remove
pulley assembly.
10. Remove field coil harness clip using a screwdriver.

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 contact surface of
pulley shows 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
With Gasoline Engine (CWV-615M Compressor)
1. Install field coil.
Be sure to align the coil's pin with the hole in the compressor’s
front head.
2. Install field coil harness clip using a screwdriver.
3. Install pulley assembly using installer and a hand press, and
then install snap ring using snap ring pliers.
