SECTION 11
MOTOR LUBRICATION
Rotating machinery can cause injury or death. Open main disconnect, lockout
and tagout power supply to compressor package before working on the electric
motor.
Motor Lubrication –
Long time satisfactory operation of an electric motor depends in large measure on
the proper lubrication of the bearings. The following charts show recommended grease qualities and re-
greasing intervals for ball bearing motors. For additional information refer to the motor manufacturer
’s
instructions. The following procedure should be used in re-greasing:
1.
Disconnect, lockout and tagout power supply to the compressor package.
2.
Locate the automatic grease relief fittings (one at each motor bottom end) and make sure that
their spring loaded covers are operational.
3.
Locate the grease fittings provided at each motor top end. Wipe each grease fitting clean and
add grease with a hand-operated grease gun until excess grease starts draining from the
companion grease relief fitting. Make sure that the grease volume does not exceed the motor
manufacturer
’s recommendation by a factor of approximately 2X.
4.
Wife off excess grease expelled by the automatic grease relief fittings.
5.
Re-start the unit.
