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.
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
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, tighten the bolt
to 14 N·m (1.4 kg-m, 10 ft-lb) torque.
After tightening the bolt, make sure 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.
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.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 for A/C piping with new one, then apply compressor oil to it when installing it.

Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
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.

172, "AIR CLEANER AND AIR DUCT" (VK45DE).
3. Remove mounting bolt for high-pressure flexible hose bracket.
4. Disconnect one-touch joint between high-pressure flexible hose
and condenser.
a. Set a disconnector (92530-89912) on A/C piping.
b. Slide a disconnector upward until it clicks.
c. Slide A/C piping upward and disconnect it.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
5. Remove mounting nut for high-pressure flexible hose (compres-
sor side), and then remove high-pressure flexible hose.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air. Bolt mounting the low-pressure flexible hose bracket
