Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check appearance of pulley assembly. If contact surface of pulley
shows signs of excessive grooving, replace clutch disc and pulley.
Contact surfaces of pulley assembly should be cleaned with a suit-
able solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.
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.
4. Install clutch disc on drive shaft, together with original shim(s). Press clutch disc down by hand.

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

Replace O-rings of low-pressure flexible hose and low-pressure pipe (VK45DE) with new ones,
and then apply compressor oil to it when installing it.

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

Insert piping securely until a click is heard.

After piping connection is completed, pull male-side piping by hand to make sure that connection
does not come loose.

When recharging refrigerant, check for leaks.
