A/C Compressor Removal and Installation

Compressor And Tension Pulley Replacement:

REMOVAL
For removal follow steps in the image and note the following:

Removal Service Point:

Step 1 -- Compressor Drive Belt Removal
1. Loosen nut "A" for holding the tension pulley.
2. Loosen bolt "B" for adjustment.
3. Remove the compressor drive belt.

Step 10 -- Compressor Removal
When doing this work, be careful not to spill the compressor oil.


INSTALLATION
For installation reverse the steps in the image and note the following:
Step 10 -- Compressor Removal
If a new compressor is installed, first adjust the amount of oil according to the procedures described below, and then install the compressor.
1. Measure the amount [X Cubic Cm (x fl oz)] of oil within the removed compressor.
2. Drain (from the new compressor) the amount of oil calculated according to the following formula, and then install new compressor.

New compressor oil amount
- 170 Cubic Cm - X Cubic Cm = Y Cubic Cm
- (5.7 fl oz - x fl oz y fl oz)

NOTES:
- Y Cubic Cm (y fl oz) indicates the amount of oil in the refrigerant line, the condenser, the evaporator etc.
- When replacing the following parts as well as the compressor, subtract the rated oil amount of the each part from Y Cubic Cm (y fl oz) and discharge from the new compressor.

Refrigerant Oil Quantity
- Evaporator 60 Cubic Cm (2.03 fl oz)
- Condenser 15 Cubic Cm (0.51 fl oz)
- Suction hose 10 Cubic Cm (0.34 fl oz)
- Receiver 10 Cubic Cm (0.34 fl oz)

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