Replacement

Pre-Removal and Post-Installation Operation
- Refrigerant Discharging and Charging Refrigerant System Charge
- Compressor Drive Belt

CAUTION: Plug refrigerant lines to prevent air from mixing when disconnecting them.

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




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 8 --- 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 8 --- Compressor Installation
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.)

NOTE:
1. Y cubic cm (y fl.oz). indicates the amount of oil in the refrigerant line, the condenser, the evaporator etc.
2. 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.
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.
