MOTOR RE-LUBRICATION INSTRUCTION

General
Johnson Controls supplied electric drive motors have
maintenance requirements for re-lubrication (greasing)
of the drive end (DE) and non-drive end (NDE) ball
bearings.
In recent years the type of grease to be utilized is typi-
cally identified on the motor data plate. Below, in Table
3 on page 32, we have provided a quick guide. How-

* Never mix grease type or brand. If changing from or to the alternate or preferred, the bearing cavities, housings, and lines must be cleaned
of the old grease.
** Follow all standard lookout tag out procedures prior to greasing motor.
** After greasing motor at rest, run motor for a minimum of 45 minutes before replacing plug if equipped.
*** Motor must be equipped with grease extensions on DE bearing for performance of this task.
Verify with motor nameplate any discrepancy before lubricating - contact technical support for additional information/clarification.
Remove grease plug, if equipped, prior to greasing. Not every grease interval will result in used grease discharge.
