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

4. Install the clutch disc on the drive shaft, together with the original
shim(s). Press the clutch disc down by hand.
5. Using the holder to prevent clutch disc rotation.
After tightening the bolt, check that the pulley rotates smoothly.
6. Check clearance around the entire periphery of clutch disc.
If the specified clearance is not obtained, replace adjusting
spacer and readjust.
With Diesel Engine (DKV-11G Compressor)
1. Install the field coil.
Be sure to align the coil's pin with the hole in the compressor's
front head.
2. Install the field coil harness clip using a screwdriver.

Break-In Operation
When replacing compressor clutch assembly, always carry out the break-in operation. This is done by engag-
ing and disengaging the clutch about thirty times. Break-in operation raises the level of transmitted torque.
