5. Lift out the air/oil separator elements.
6. Inspect and/or replace the separator as necessary.
7. Clean the sealing surfaces on the air/oil separator and the minimum pressure/check valve.
8. Clean the orifice, in the oil return line, the strainer in oil return line, and if necessary, the air/oil
separator housing.
9. Grease the O-Ring on the separator element and install the separator into the housing.
10. Replace the O-Ring between the minimum pressure/check valve and the air/oil separator housing.
11. Replace the sealing kit in the minimum pressure/check valve. After the assembling of the valve,
leave about .08 inch gap between the nut and the cover of the valve. See “Changing Minimum
Pressure/Check Valve Seals,” Section 4, page 35.
12. Install the minimum pressure/check valve assembly and tighten the bolts alternately for even
tightness.
13. Open the air service valve.
14. Run the unit and check for leaks.
COMPRESSOR OIL SYSTEM CHECK - The following readings are based on ambient temperature of
80
°
F (27
°
C) with the system in good condition. The compressor should be at operating temperature at
the time of the checks. One-half hour of loaded operation is usually sufficient to reach level-out operating
temperatures.
Air and Oil Discharge Temperature - 170
°
F to 200
°
F (77
°
C to 93
°
C) - Check with a thermometer at
the discharge housing.
Compressor Oil Inlet Temperature - 160
°
F to 175
°
F (71
°
C to 79
°
C) - Install a tee at the oil filter outlet
and check with a thermometer.
Oil Inlet Pressure - Check at the fitting in the line near the compressor oil inlet. With air receiver
pressure at 100 psi (6.9 bar), oil inlet pressure should be 80 to 90 psig (5.5 to 6.2 bar).
Oil Cooler Oil Pressure Differential - Check differential across the oil system by measuring oil inlet
pressure as described above.
Oil Cooler Temperature Differential - The oil temperature differential depends on the temperature of the
air at the oil cooler fan and cleanliness of the core faces. As ambient temperatures and core restrictions
increase, the oil cooler outlet temperature will increase. The oil inlet temperature is approximately the
same as the air discharge temperature.
