SECTION 13
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
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 end of the motor top end – be aware the one or both may
be relocated away from the motor for easier access. Wipe each grease fitting clean and add grease
with a hand - operated 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. Wipe off only excess grease expelled by the automatic grease relief fittings.
5. Re-start the unit.
