Inspection
1. Drive Plate
If the contact surface is scorched, the drive plate and
pulley should be replaced.
2. Pulley Assembly
Inspect the appearance of the pulley assembly. If the
pulley’s contact surface is excessively grooved due to
slippage, both the pulley and drive plate must be
replaced. There should also be no foreign matter, such
as oil or grit, lodged between the clutch plate and
pulley. Thoroughly clean these contact surfaces and the
drive plate.
3. Coil
Inspect the coil for a loose connector or cracked insula-
tion. If the insulation is cracked, replace the coil.
Repair or replace the wire or the connector if either is
loose or damaged.
Clutch Installation
NOTE: Before installation refer to the “Inspection”
procedures previously described.
1. Confirm that the felt is installed on the front of the
cylinder head.
2. Install the coil on the compressor (with the lead wire on
top). At this time, confirm that the coil’s concave por-
tion is aligned with the felt and then tighten the mount-
ing screws to the specified torque.
NOTE: Specified torque: 2.9 to 4.3 ft-lbs (0.4 to
0.6 kgm).
3. Install the lead wire in the wire holder on the
compressor.
