Disassembly and Reassembly

DISASSEMBLY AND REASSEMBLY

DISASSEMBLY SERVICE POINTS





REFRIGERANT-TEMPERATURE SWITCH REMOVAL
(1) Remove the compressor fitting block.
(2) Disconnect the snap ring from the inside of the fitting block to remove the refrigerant-temperature switch.





NUT REMOVAL
Use the special tools to remove the nut.

REASSEMBLY SERVICE POINTS





CLUTCH COIL INSTALLATION
When installing the clutch coil to the A/C compressor body, install so that the pin hole of the NC compressor body and the clutch coil projection are aligned.





SNAP RING INSTALLATION
Install the snap ring so that the tapered surface is at the outer side.





ARMATURE PLATE INSTALLATION
Align the mating mark of the crankshaft spline and the mating mark of the armature plate, and then fit them together.





NUT INSTALLATION
Use the special tools to remove the nut.





AIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is within the standard value.

Standard value: 0.4-0.65 mm (.016-.0256 in.)

NOTE: If there is a deviation of the air gap from the standard value, make the necessary adjustment by adjusting the number of shims.

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.

REFRIGERANT-TEMPERATURE SWITCH CONTINUITY CHECK





(1) Immerse the refrigerant-temperature switch in engine oil.





(2) Use an ohmmeter to check the continuity between the terminals (1) or (2) when the engine oil has become heated.

CAUTION: Do not heat the oil more than necessary.





HIGH PRESSURE RELIEF VALVE CHECK
The high pressure relief valve is a safety feature which releases part of the refrigerant inside the system into the atmosphere when the high pressure level exceeds 3,740 kPa (532 psi) during air conditioning operation.

Once the pressure inside the system has been reduced to 2,940 kpa(418 psi) or lower, the high pressure relief valve closes, thus allowing continued operation.
(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 retightening the valve, replace the packing.
