Motor Lubrication Procedure
Be sure that the grease you are adding to the motor is compatible with the grease already in the
motor. Consult your Baldor distributor or an authorized service center if a grease other than the
recommended type is to be used.
A high grade ball or roller bearing grease should be used. Recommended grease for standard
service conditions is Polyrex EM (Exxon Mobil).
Equivalent and compatible greases include:
Texaco Polystar, Rykon Premium #2, Pennzoil Pen 2 Lube and Chevron SRI.

With Grease Outlet Plug
1. Clean all grease fittings.
2. Remove grease outlet plug.
3. If motor is stopped, add the recommended amount of grease. If motor is to be greased
while running, a slightly greater quantity of grease will have to be added. Add grease
slowly until new grease appears at shaft hole in the endplate or purge outlet plug.
4. Re-install grease outlet plug.
Without Grease Outlet Plug
1. Disassemble motor.
2. Add recommended amount of grease to bearing and bearing cavity. (Bearing should be
about 1/3 full of grease and outboard bearing cavity should be about 1/2 full of grease.)
Note: Bearing is 1/3 full when only one side of bearing is completely full of grease.
3. Assemble motor.
