Warning: Ensure the brush pressure is correctly established and maintained at the correct value throughout the life of the brush.

Ensure brushes and brush−holders are clean so that the brushes are free to move in the holders.

Replace brushes with new brushes of the same grade before wear permits the rivet or tamped pigtail to score the commutator.

Remove hand hole covers from each side of the opposite drive end bracket.

Loosen four (4) hex head cap bolts which hold the rocker ring assembly to the bracket.

Remove brushes from the holder by lifting the brush finger and removing the hex head cap bolt which secures the brush lead to the holder.

Depends on Service Condition Lubrication Schedule could change: Standard Service – 36 Months, Severe Service – 12 Months, Extreme Service – 3 Months

Bearing grease will lose its lubricating ability over time, not suddenly. The lubricating ability of a grease (over time) depends primarily on the type of grease, the size of the bearing, the speed at which the bearing operates and the severity of the operating conditions.

Good results can be obtained if the following recommendations are used in your maintenance program. Relubrication with the shaft stationary and a warm motor is recommended.

RPMIII motors have the exclusive Positive Lubrication System PLS which routes new grease directly into the bearing.

Note: Certain special motors may have a lubrication instruction plate permanently attached. These specific lubricating instructions must be followed.

Relubrication with the shaft stationary and a warm motor is done?

All dirt from the outside of the grease fills and drains wiped?

Grease inlet at the top of the bearing hub located, area cleaned and 1/8−inch pipe plug replaced with a grease fitting if the motor is not equipped with grease fitting?

Grease drain plug located opposite the grease inlet removed?
