Adding Compressor Oil Using Oil Pump. The following steps describe how to add oil to the compressor using an
oil pump.
1. Remove protective caps (Figure 2, Item 5) from suction (Figure 2, Item 1) and discharge (Figure 2, Item 2)
service valves.
2. Install manifold gauges.
3. Pump refrigerant unit down (WP 0014, Service).
4. Frontseat (close) suction (Figure 2, Item 1) and discharge (Figure 2, Item 2) service valves.
NOTE
There may be some residual pressure in the compressor. Equalizing the pressure will
allow for easier removal of fill plug and prevent excessive pressure release.
5. Equalize pressure by fully opening manifold gauge valves.
6. Remove compressor oil fill plug (Figure 2, Item 3).
7. Insert one hose from pump (Figure 2, Item 8) into oil container and one hose into compressor oil fill hole.
NOTE
Certain versions of the compressor installed on the MTRCS refrigeration unit contain
minimum and maximum indicator lines by the compressor sight glass. Other versions
of the compressor do not.
8. Using oil pump (Figure 2, Item 8), add oil as needed through oil fill plug (Figure 2, Item 3) opening. Oil level in
sight glass should indicate oil level is halfway between minimum and maximum when ambient.
9. Install and tighten compressor oil fill plug (Figure 2, Item 3).
10. Perform evacuation and dehydration (WP 0014, Service).
11. Fully close manifold gauges.
12. Fully backseat (open) suction (Figure 2, Item 1) and discharge (Figure 2, Item 2) service valves.
13. Frontseat (close) suction (Figure 2, Item 1) and discharge (Figure 2, Item 2) service valves 1/4-turn each.
14. Backseat (open) receiver outlet valve (Figure 2, Item 7).
15. Start refrigeration unit (TM 10-8145-222-10, Operating Procedures).
16. Charge system with refrigerant as needed (WP 0014, Service).
