III-91
After finding a leak, recover all refrigerant from the system
and repair the leak. Check the compressor and replace any
refrigeration oil lost due to leakage. Evacuate and recharge
the system with refrigerant, then check AC operation and
performance.
Air and/or Moisture in the System
Tip:
The sight glass may be clear or show some bubbles. The
air from vents in the cab is only slightly cool. In a cycling
clutch type system with a thermostatic switch, the switch
may not cycle the clutch on and off, so the low pressure
gauge will not fluctuate.
Cause:
Air and/or moisture in the system.
RepairProcedure:
Test for leaks, especially around the compressor shaft seal
area. When the leak is found, recover refrigerant from the
system and repair the leak. Replace the receiver-drier or
accumulator because the desiccant may be saturated with
moisture (there is no way to tell). Check the compressor
and replace any refrigeration oil lost due to leakage. Evacu-
ate and recharge the system with refrigerant, then check AC
operation and performance.
