Lubrication – Frames C180ATZ
These motors are designed to route new grease directly into the bearing.
The relubrication periods shown in
Table J 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.
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. When provided, remove grease drain plug located opposite the grease
inlet. The following motors do not have a grease drain plug, but have a
grease relief around the grease inlet pipe:
– Frames C180ATZ on commutator end (opposite drive end).
– All C-Face and D-Flange frames on drive end.
4. Using a manual grease gun, pump in the recommended grease in the
amount shown in
Table H. This amount of grease will provide an ample
supply of lubricant between lubrication periods as determined from
Table J for the service condition listed in Table I. An excessive amount
of grease will damage the motor.
Use Chevron SRI-2 grease or equivalent unless motor nameplate
specifies special grease. Use only clean, fresh grease from clean
containers and handle carefully to keep it clean.

ATTENTION: To guard against personal injury or death from
rotating parts or electrical shock, relubrication should only be
performed while the motor is stationary and disconnected from
the power source.
