REMOVE AND REPLACE
When refrigeration system components other than the
compressor are replaced, the compressor must be removed
and oil drained from the compressor if oil was sprayed in
large amounts due to leaks or broken shaft seal. See

Compressor shaft seals, unless replaced during a compres-
sor overhaul, are to be replaced only on the basis of actual
refrigerant leakage as determined by test with a propane
torch (or electronic) type leak detector in good condition.
REMOVE:
1. Disconnect thermal limiter and jumper terminals B
and C of limiter connector.
2. Depressurize refrigerant system.
3. Remove hub and drive plate assembly and shaft key.
