8.20 — Lubrication
8.20.1 — Electric Motors
Manufacturers of electric motors vary in their specifications for lubrication
and care of motor bearings; however, their specific recommendations should
be followed.
Ball-bearing-equipped motors are pre-lubricated. The length of time a bear-
ing can run without grease added will depend on many factors, including
the rating of the motor, type of motor enclosure, duty, atmospheric condi-
tions, humidity, and ambient temperatures.

Complete renewal of grease, when necessary, can be accomplished by forcing out the old grease with the new
grease. Thoroughly wipe those portions of the housing around the filler and drain plugs (above and below bear-
ings). Remove the drain plug (bottom) and free the drain hole of any hardened grease which may have accumu-
lated. With the motor not running, add new grease through the filler hole until clear grease starts to come out of
the drain hole. Before replacing the drain plug, run the motor for 10 to 20 minutes to expel any excess grease.
The filler and drain plugs should be thoroughly cleaned before they are replaced.
The lubricant used should be clean and equal to one of the good commercial grades of grease locally available.
Some commercially available lubricants are:
• Gulf Oil - Precision Grease No. 2
