CAUTION:
• Replace O-rings with new ones. Then apply compressor oil to them when installing.
• Perform lubricant adjusting procedure before installing new compressor. Refer to
Adjusting Procedure for Compressor Replacement"
• Check for leakages when recharging refrigerant. Refer to
• Check tension of the drive belt after installing compressor. Refer to

REMOVAL
Overhaul
1.
Fix clutch disc.
2.
Remove center bolt, and then remove clutch disc.

cially available pulley puller.
To prevent pulley groove from being deformed, puller claws should be positioned into the edge of the pul-
ley assembly.
5.
Disconnect field coil harness connector from compressor unit.
6.
Remove snap ring using external snap ring pliers, and then remove field coil.

COMPRESSOR
3.
Install pulley assembly (1) using pulley installer
(SST:KV99106200) (A) and a hand press, and then install snap
ring (2) using snap ring pliers.
4.
Install clutch disc on drive shaft, together with original shim(s). Press clutch disc down by hand.
5.
Tighten center bolt to the specified torque while fixing clutch disc not to rotate.
After tightening the bolt, check that the pulley rotates smoothly.
Break-in Operation
When replacing compressor clutch assembly, always perform the break-in operation, by engaging and disen-
gaging the clutch approximately 30-times. Break-in operation increases the level of transmitted torque.
