Dry all parts with compressed air and relubricate them
with compressor oil.
If you must change the rotor bearings and races, you
should do so with suitable pullers and installers. In
extreme circumstances, some manufacturers
recommend heating the inner races to ease removal.
Disgard bearing races that have been heated in this type
of removal process.
Some rotary and screw types of air compressors
have an oil pump in the lubrication system.
Disassemble, inspect, and overhaul the oil pump
according to the manufacturers specifications.
Before you reassemble the air compressor, make
sure all the air and oil passages are clean. All parts
should be lightly oiled and ready for use. The
reassembly process of air compressors is not
complicated, but stick to the instructions in the
manufacturers repair and maintenance manual.
The manufacturers of the screw type of air
compressors do not recommend that overhaul be done
in the field.
As a parting shot, you can get the most out of this
machinery by PERFORMING PREVENTIVE
MAINTENANCE AS REQUIRED. The importance of
timely oil, oil filter, and air filter changes cannot be
overstressed. Do your job and this unit will do its job.
