Lubrication - Frames L180 - L440
These motors are designed to route new grease directly into the
bearing. The relubrication periods shown in
Table H are offered as a
guide for varying service conditions, speeds, bearing types and
operating hours.
Important: Certain special motors may have a lubrication instruction
plate permanently attached. These specific lubricating
instruction must be followed.
Lubrication Procedure
1. Relubrication with the shaft stationary and a warm motor is
recommended. If lubrication must be done with the motor
running, stay clear of rotating parts and electrical circuits.
2. Locate the grease inlet at the top of the bearing hub, clean the
area and replace the 1/8 inch pipe plug with a grease fitting (if the
motor is not equipped with a grease fitting).
3. Remove grease drain plug located opposite the grease inlet.
4. Using a manual grease gun, pump in the recommended grease in
the amount shown in Table F . This amount of grease will provide
an ample supply of lubricant between lubrication periods as
determined from
Table H for the service condition listed in Table
G .

ATTENTION: If relubrication is done while motor is
running, stay clear of rotating parts. Failure to observe this
precaution could result in personal injury.
