4.10 MOTOR LUBRICATION

The induction-type squirrel cage motors have antifriction ball or roller bearings front and rear. At periodic intervals they require relubrication.

Improper lubrication can be a cause of motor bearing failure. The quantity of grease added should be carefully controlled. The smaller motors must be greased with a lesser amount of grease than larger motors.

CAUTION

Overgreasing can be a cause of bearing and motor failure. Make sure dirt and contaminants are not introduced when adding grease.

Procedure for relubrication

CAUTION

Grease should be added when the motor

is stopped and power disconnected.

When regreasing, stop motor. Disconnect power; lock out and tag. Remove outlet plugs (or spring-loaded grease relief plugs if present). The outlet plug may not be accessible on the fan end of some TEFC motors.

NOTICE

Motors must be greased periodically.

See Operator’s Manual for procedure.
