Installation is basically the reverse order of removal.

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 

HA-27, "Lubricant

Adjusting Procedure for Compressor Replacement"

.

• Check for leakages when recharging refrigerant. Refer to 

HA-22, "Leak Test"

.

• Check tension of the drive belt after installing compressor. Refer to 

EM-13, "Checking"

REMOVAL

Overhaul

1.

Fix clutch disc.

2.

Remove center bolt, and then remove clutch disc.

3.

Remove snap ring using external snap ring pliers.

4.

Position center pulley puller on the end of the drive shaft, and remove pulley assembly using any commer-
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.

INSTALLATION

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.

Inspection

INFOID:0000000009950351

CHECK DISC TO PULLEY CLEARANCE

Check the clearance (B) between pulley assembly (1) and clutch
disc (2) along the entire periphery with a feeler gauge (A).

Replace compressor if specified clearance is not obtained.
