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.
