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.
Overhaul (With Diesel Engine: DKV-11G Compressor)

2. When removing center bolt, hold clutch disc with clutch disc
wrench.
3. Remove the drive plate using the clutch disc puller.
4. Insert holder's three pins into the drive plate. Rotate the holder
clockwise to hook it onto the plate.
5. Tighten the center bolt to remove the drive plate.
6. While tightening the center bolt, insert a screwdriver between
two of the pins (as shown in the figure) to prevent rotation.
7. After removing the drive plate, remove the shims from either the
drive shaft or the drive plate.
8. Remove the snap ring using external snap ring pliers.
9. Remove the pulley assembly with the puller using a commer-
cially available pulley puller. (Position the center of the puller on
the end of the drive shaft)
For pressed pulleys:
To prevent deformation of the pulley groove, the puller claws
should be hooked under (not into) the pulley groove.
For machine lathed pulleys:
Align the pulley puller groove with the pulley groove, and then
remove the pulley assembly.
10. Remove the field coil harness clip using a screwdriver.
11. Then remove the three field coil fixing screws and remove the
field coil.

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.
