The procedure to replace compressor is as follows :----
Removal & Installation details are mentioned below:---
CAUTION
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 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
If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.
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.
NOTE
The A/C compressor mounting bolts must be removed with the A/C compressor. If flushing of the refrigerant system has not been performed, recover the refrigerant.
Remove the generator.
Raise the vehicle.
Completely loosen the lower A/C compressor mounting bolts.
Loosen the bolt and disconnect the compressor manifold and tube assembly from the A/C compressor.
Lower the vehicle.
Disconnect the A/C compressor clutch field coil electrical connector.
Completely loosen the A/C compressor mounting bolt.
Remove the three bolts from the A/C mounting bracket.
Remove the bolts from the generator mounting bracket.
Completely loosen the generator mounting bracket bolt.
Lift the generator mounting bracket until the remaining bolt clears the frame rail and remove the bolt. Remove the generator mounting bracket.
Detach the wiring harness pin-type retainer from the A/C mounting bracket and remove the bracket.
Disconnect the compressor manifold and tube assembly from the suction accumulator. Position the compressor manifold and tube assembly aside.
Discard the O-ring seal.
Completely loosen the remaining bolt and remove the A/C compressor and A/C mounting brace.
Discard the O-ring seals.
To install:
Install the A/C compressor and A/C mounting brace.
Connect the compressor manifold and tube assembly to the suction accumulator.
Attach the wiring harness pin-type retainer to the A/C mounting bracket and remove the bracket.
Install the three bolts from the A/C mounting bracket.
Connect the A/C compressor clutch field coil electrical connector.
Replace the generator mounting bracket.
Install the generator.
If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit.
If filtering of the refrigerant system is not be to performed, lubricate the refrigerant system with the correct amount of clean PAG oil or equivalent.
Install new O-ring seals lubricated with clean PAG oil or equivalent.
If filtering of the refrigerant system is not to be performed, evacuate, leak test and charge the refrigerant system.
This will help.
Thanks.
