Installation

1. Ensure that shaft seal contact surface is free of dirt and amply lubricated with clean refrigerant oil.
2. Cap shaft seal pilot KV99412322 or equivalent on other models, to top end of compressor shaft.
3. Using shaft seal remover and installer, KV99412321 or equivalent, insert shaft seal with shaft seal case and shaft cutout aligned.
4. Apply force to turn seal somewhat to left and right, ensuring that shaft seal seats properly in shaft cutout.
5. Fit new O-ring to outside groove of shaft seal seat, ensuring that it seats properly.
6. Apply refrigerant oil to contact surface and around shaft seal seat, so that it can slide easily in front cover.
7. Lightly coat surface of shaft with refrigerant oil, then push in shaft seal until it seats properly at land of front cover.
8. Using suitable pliers, compress retaining ring and fit it into front cover. Seat retaining ring firmly in groove and thoroughly wipe oil from shaft surface.
9. Check for gas leakage as follows:
a. Plug high and low pressure joints on compressor with blind caps.
b. Connect charging hoses in lines between manifold gauge and high and low pressure service valves.
c. Connect refrigerant can to middle hose of manifold gauge.
d. Open valve of can top, charge refrigerant through low pressure service valve, and purge air from high pressure service valve.
e. Install shaft handle socket KV99412329 or equivalent to shaft of compressor and turn shaft 5 to 6 turns clockwise.
f. Perform leak test. If there is a leak, remove and reinstall parts.
10. Install compressor clutch assembly.
11. Charge compressor with new refrigerant oil in amount equal to that previously removed.
