Refrigerant Oil: Service and Repair
Adjusting for Compressor Replacement
1. Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed, recover refrigerant from equipment lines
and then check refrigerant purity.
2. Confirm refrigerant purity in supply tank using ACR4 and refrigerant identifier.
3. Confirm refrigerant purity in vehicle A/C system using ACR4 and refrigerant identifier.
4. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into the recovery/ recycling equipment.
5. Remove the drain plug of the "old" (removed) compressor. Drain the lubricant into a graduated container and record the amount of drained
lubricant.
6. Remove the drain plug and drain the lubricant from the "new" compressor into a separate, clean container.
7. Measure an amount of new lubricant installed equal to amount drained from "old" compressor. Add this lubricant to "new" compressor through the
suction port opening.
8. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant to "new" compressor through the
suction port opening.
9. Torque the drain plug.
Ford Model FS10 compressor:
18 - 19 N.m (1.8 - 1.9 kg-m, 13 - 14ft-lb)
10. If the accumulator also needs to be replaced, add an additional 5 ml (0.2 US fl oz, 0.2 Imp fl oz) of lubricant at this time. Do not add this 5 ml
(0.2 US fl oz, 0.2 Imp fl oz) of lubricant if only replacing the compressor.
