Replacement Nippondenso compressor, updating

Note:
Replacement compressors are factory filled with R-12 compatible compressor 011 which must be drained and replaced with appropriate quantity of PAG refrigerant oil.

- Obtain Nippondenso retrofit kit:
Part No. 4A0 298 107 A

- Relieve nitrogen charge in replacement compressor by carefully loosening protective caps on suction and discharge ports.
- Drain and measure amount of existing refrigerant oil at high and low service ports (rotating compressor via the clutch will aid draining).
- Replace shaft seals (if necessary*), See Retrofit Procedures.
- Replace manifold seals (if necessary*), See Retrofit Procedures.
- Fill with same amount of PAG refrigerant oil measured when draining.
