1. SCOPE 

 

To give recommended guidelines for electric motor relubrication. 

 

2. START 

UP

 

 

Toshiba motors are properly greased at the time of manufacture.  It is recommended that 
if a motor has been stored for a period of six months or more, it should be lubricated prior 
to starting (See Fig. 1) using a standard hand held grease gun.

It should be noted that grease leakage around the shaft hole could indicated over-
packing.  Excess grease should be purged out by operating the motor temporarily with 
the relief open. 

 
 

Lubrication of electric motors should be done as a part of a planned maintenance 
program. 

 
 

Before greasing, be sure fittings are clean and free from dirt.  Always relubricate using 
grease that is fresh and free from contamination. 

 
 

Toshiba motors may be equipped with an automatic grease relief fitting, grease plug or 
grease cover plate for the outlet. 

 
 

It should be noted that it may be necessary to remove an automatic type fitting due to 
hardening of grease.  Motors utilizing a grease plate may require the scraping out of old 
grease a minimum of once every two years.
