Compressor HVAC: Service and Repair

REMOVAL

CAUTION: If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out the flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure.
- Install a new suction accumulator as directed by the A/C flushing or filtering procedure.

NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

1. If flushing of the refrigerant system has not been performed, recover the refrigerant.
2. Remove the drive belt from the A/C compressor pulley.







3. Disconnect the electrical connector.







4. Disconnect the compressor manifold and tube assembly from the A/C compressor.
1 Loosen the bolt.
2 Disconnect and position aside the compressor manifold and tube assembly.







5. Remove the A/C compressor.
1 Remove the bolts.
2 Remove the A/C compressor.
^ Discard the O-ring seals.

INSTALLATION
1. To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the A/C compressor clutch field coil and the A/C clutch plate must be transferred from the old unit.
- If filtering of the refrigerant system is not to be performed, lubricate the refrigerant system with the correct amount of clean PAG oil or equivalent.
- Install new O-ring seals lubricated in clean PAG oil or equivalent.

2. If filtering of the refrigerant system is not to be performed, evacuate, leak test, and charge the refrigerant system.
