A/C Compressor Disassembly and Reassembly




DISASSEMBLY




Step 1 --- Clutch Hub Removal

1. Remove the clutch hub mounting bolt.
2. Tighten a phi 10 mm (0.39 in.) bolt into the bolt hole of the clutch hub to remove the serration assembly of the shaft and the clutch hub.

REASSEMBLY




Step 11 --- Shaft Seal Installation
Use a 21 mm (0.83 in.) socket to install the shaft seal so that the O-ring assembly side is facing the front housing.




Step 8 & 9 --- Felt, Felt Holder Installation
Install the felt in the felt holder, and then install them to the front housing using a 14 mm (0.55 in.) deep socket.




Step 7 --- Front Housing Installation
1. Apply compressor oil to the shaft.
Compressor oil: ND-OIL 8
2. install the front housing without damaging the shaft seal lip.




3. After installing the front housing, install the clutch hub mounting bolt to the shaft, and check that the breakage torque is within the specified torque value.

Breakaway torque: 5 Nm (4 ft.lbs.) or less




Step 6 --- Clutch Coil Installation
Set the clutch coil pin in the compressor housing notch, and install the clutch coil.




Air Gap Adjustment
Apply battery voltage to the magnetic clutch and check that the air gap is within the standard value. If the air gap is outside the standard value, adjust with a shim.
Standard value: 0.35 - 0.65 mm (0.0138 - 0.0256 in.)

NOTE: If there is a deviation of the air gap from the standard value, adjust the number of shims.

INSPECTION
- Checking for heat damage of the tension pulley.
- Check for excessive play or deflection of the tension pulley.
- Check for unusual wear of the tension pulley.
- Check for hardening of the compressor drive belt.
- Check for unusual wear or abrasion of the compressor drive belt.
