4.5 Air Compressor Maintenance
The P07102 maintenance kit contains parts necessary for scheduled routine maintenance on
the nitrogen bottle replacement module when operated under normal conditions. Refer to
Figure 6. The contents of the maintenance kit are as follows:
If the air compressor shows evidence of overheating or excessive noise, stop immediately for
repairs.
Regular inspection may prevent expensive repairs. The rider ring thickness can indicate
when the air compressor needs maintenance. If a rider ring measures .055 inches or less in
thickness, the maintenance kit, P07102 should be installed. The thickness of a new rider ring
is .060 inches.
The wear of the air compressor rings are affected by ambient conditions. At 80
o
F. maximum
ambient temperature and relative humidity 40% maximum average, it is suggested the
compressor life between maintenance be approximately 4,000 hours of run time.
The air compressor is oilless and requires no lubrication. It is recommended the piston rings,
piston seals, rider rings, inlet valves, valve plates and gaskets be replaced at 4,000 hours of
run time.
