WARNING
Before performing any of the scheduled maintenance tasks in this chapter,
the compressor should be shut off and tagged
Out of Service . This is to
prevent an inadvertent start which could cause injury to personnel or
damage to the equipment. Allow piping to cool before repair.
5.3 FILTER: Every 3000 hours (or as required) the discharge filter should be cleaned or replaced.
5.4
CRANKCASE LUBRICATING OIL : Every 3000 hours of running time (or annually,
whichever comes first) the crankcase oil should be renewed. Failing to change the oil as scheduled may
result in premature or accelerated wear to the running gear (crankshaft, main / connecting rod bearings
and the crosshead).
5.5 MOTOR LUBRICATION: Motor bearings do not require lubrication. The bearings are
sealed for the life of the motor.
5.6 DRIVE BELTS: Properly tensioned belts insure a longer life. Correct belt tension for the 2V
unit allows one quarter inch deflection with 8-10 lb. force applied per belt at mid-span. New belts may
require tightening after 24-48 hours of operation. Two belts are required on the 2V unit. Units with the
flywheel grooves painted normally require banded belts as single belts will rotate in the grooves. Single
belts may be easier to install if the clearance between flywheel and beltguard is marginal.
5.7 PRESSURE RELIEF VALVES: The pressure relief valves should be removed from the
compressor, inspected for cleanliness, and tested for correct set-point every 8000 hours or once per year.
If a valve fails to lift at its rated pressure, it must be readjusted, and if necessary, rebuilt or replaced.
