MAINTENANCE / LUBRICATION

 
Gear units should have the oil changed every 2,500 
hours or six months. If synthetic lubricant is used, it 
should be changed every 6,000 hours or 2 years. For 
adverse operating conditions, the interval should be 
shorter. 

DO NOT MIX SYNTHETIC AND MINERAL 

BASE OILS.

 Units should be checked periodically for 

increased noise, surface temperature, vibration, shaft 
movement and amperage draw.  Units with inspection 
covers should not be operated with the inspection cover 
removed. 
 

 CAUTION 

Oil should be changed more often if reducer is used in a 
severe environment. (i.e. dusty, humid)  
 

TABLES 2

 and 

3

 offer suggestions on the viscosity and 

manufacturers of recommended lubricants. Some gear 
lubricants contain E.P. additives that can be corrosive to 
gear bronze. Avoid lubricants that are compounded with 
sulfur and/or chlorine. 
 
Always check for proper oil level after filling. Capacities 
vary somewhat with model and mounting position. Oil 
should rise to bottom edge of level hole. Do Not Overfill.

Reducers ordered from the factory will be filled to the 
proper level with lubricant. After the installation of the 
breather plug, the unit is ready for use. Before installing 
the breather plug, refer to the instruction tag and 
determine the proper position according to reducer 
mounting specifications. 
 
 

 CAUTION 

In the Food and Drug Industry (including animal food), 
consult the lubrication supplier for recommendation of 
lubricants which are acceptable to the Food and Drug 
Administration and/or other authoritative bodies having 
jurisdiction. Factory supplied oil is not suitable for these 
applications or this industry. 
 
To assist you in the proper selection of replacement 
lubricant, we recommend the following oils for the 
ambient temperatures specified.
