31. Apply a small amount of refrigerant oil to ORS fitting (Figure 2, Item 9) with O-ring (Figure 2, Item 11) in place.
32. Install TXV (Figure 2, Item 12) and tighten ORS fitting (Figure 2, Item 9) onto liquid line (Figure 2, Item 10).
33. Install TXV bulb (Figure 2, Item 5) with clamp (Figure 2, Item 7) into position on suction line (Figure 2, Item 8)
where previous noted during removal, and tighten.
34. Secure capillary tube (Figure 2, Item 6) to refrigerant piping with wire ties as needed.
35. Install insulation (Figure 2, Item 15) onto TXV bulb (Figure 2, Item 5) and suction line (Figure 2, Item 8).
36. Install evaporator cover (Figure 2, Item 1) using two bolts (Figure 2, Item 2) and two washers (Figure 2, Item 3).
37. Perform evacuation and dehydration (WP 0014, Service).
NOTE
The thermostatic expansion valve replacement is preset in the factory and should not
require any adjustment. If the refrigeration unit is slow in pulling temperatures, or
pressures do not correspond to relevant temperatures after replacement of the valve,
diagnose and repair any other possible malfunctions.
38. Check refrigerant level and charge system with refrigerant as required (WP 0014, Service).
39. Operate refrigeration unit under normal conditions to ensure proper operation (TM 10-8415-222-10, Operating
Procedures).
40. Place MTRCS back into desired mode of operation (TM 10-8415-222-10, Operating Procedures).
