Lubrication – Frames C180ATZ
These motors are designed to route new grease directly into the bearing.
The relubrication periods shown in
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
. This amount of grease will provide an ample
supply of lubricant between lubrication periods as determined from
for the service condition listed in
. 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.
