INSTALLATION
1. Install field coil.
Be sure to align coil’s pin with hole in compressor’s front head.
2. Install field coil harness clip using a screwdriver.
3. Install pulley assembly using pulley installer (SST) and a hand press, and then install snap ring using snap ring pliers.

6. Check clearance around entire periphery of clutch disc.
If specified clearance is not obtained, replace adjusting spacer
and readjust.
Break-in Operation
When replacing compressor clutch assembly, always carry out break-in operation. This is done by engaging
and disengaging the clutch about thirty-times. Break-in operation raises the level of transmitted torque. Disc to pulley clear-
ance : 0.25 - 0.6 mm (0.010 - 0.024 in)

INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing
it.

to deform female-side piping. Slowly insert in axial direction.

Insert one-touch joint connection point securely until it clicks.

After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.

When recharging refrigerant, check for leaks.
