lPulley removal
Position the center pulley puller on the end of the drive shaft,
and remove the pulley assembly using any commercially
available pulley puller.
To prevent the pulley groove from being deformed, the
puller claws should be positioned onto the edge of the
pulley assembly.
lRemove snap ring (which secures field coil) by using exter-
nal snap ring pliers.
INSPECTION
Clutch disc
If the contact surface shows signs of damage due to excessive
heat, the clutch disc and pulley should be replaced.
Pulley
Check the appearance of the pulley assembly. If the contact
surface of the pulley shows signs of excessive grooving due to
slippage, both the pulley and clutch disc should be replaced. 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
lPosition the field coil.
Be sure to align the coil's pin with the hole in compressor's
front head.
lInstall snap ring (which secures field coil) by using external
snap ring pliers.

lPosition and install pulley assembly securely by using plas-
tic hammer.
lInstall snap ring (which secures rotor pulley) by using exter-
nal snap ring pliers.
lInstall the clutch disc on the drive shaft, together with the
original shim(s). Press the disc down by hand.
lUsing the clutch wrench disc to prevent clutch disc rotation,
tighten the bolt to 12 to 15 N´m (1.2 to 1.5 kg-m, 9 to 11 ft-lb)
torque.
After tightening the bolt, check that the pulley rotates
smoothly.
lCheck clearance around the entire periphery of clutch disc.
Disc-to-pulley clearance:
0.3 - 0.6 mm (0.012 - 0.024 in)
If the specified clearance is not obtained, replace adjusting
spacer and readjust.
BREAK-IN OPERATION
When replacing compressor clutch assembly, do not forget
break-in operation, accomplished by engaging and disengaging
the clutch about thirty times. Break-in operation raises the level
of transmitted torque.
Thermal Protector
INSPECTION
lWhen servicing, do not allow foreign matter to get into com-
pressor.
lCheck continuity between two terminals.
