Disassembly and Reassembly

DISASSEMBLY SERVICE POINTS





Clutch hub removal
(1) Remove the clutch hub mounting blot.
(2) Tighten a 10 mm (.39 in.) bolt into the bolt hole of the clutch hub to remove the serration assembly of the shaft and the clutch hub.

INSPECTION
- Check the surface of the armature for scoring or bluing Check the surface of the rotor for scoring or bluing.
- Check the sealing surfaces for cracks, scratches and deformation
- Check the front housing for cracks or scoring on the sealing surfaces.
- Check the compressor shaft for scoring.





REVOLUTION PICKUP SENSOR CHECK
Check the resistance value between terminals (1) and (2).

Standard value: 185 ohms when at 20°C (68°F)





HIGH PRESSURE RELIEF VALVE CHECK
The high pressure relief valve is a safety feature. It releases part of the refrigerant inside the system into the atmosphere when the high pressure level exceeds 3,740 kPa (532 psi). Once the pressure inside the system has been reduced to 2,940 kPa (418 psi) or lower, the high pressure relief valve closes to keep A/C system on.
(1) If a leak is detected at section A, replace the high pressure relief valve. The valve can be used unless there is a leak from that section.
(2) If a leak is detected at section B, retighten the valve. If the leak persists after that, replace the packing.

REASSEMBLY SERVICE POINTS





Shaft Seal Installation
Use a 21 mm (.83 in.) socket to install the shaft seal so that the 0-ring assembly side is facing the front housing.





Felt, Felt Holder Installation
After installing the felt in the felt holder, Install them to the front housing using a 14 mm (.55 in.) deep socket.

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 breakaway torque is within the specified torque value.

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





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 (.0138- .0256 in.)

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