D. Gear Motor Brush Replacement 

 

 

ELECTRIC SHOCK HAZARD:

  

Do not touch live electrical parts. 

Shut down the control unit and disconnect the input power, using 
proper lockout / tagout procedures before inspecting, maintaining, or 
servicing the equipment. Lockout / tagout procedures consist of 
locking the line disconnect switch in the open position, removing 
fuses from the fuse box, or employing another disconnecting device.

 

 

D-1. Brush Removal 

 

Gear motor brush wear varies according to the duty cycle. Inspect 
brushes frequently to determine a replacement schedule. 
 
Brush caps are on lower left and lower right side of gear motor 
(item 42 in the parts list). Unscrew brush caps with an offset slot 
screwdriver then pull the brushes out of brush boxes by the cap. 

 

D-2. Brush Inspection and Cleaning 

 

Replace brushes before they wear to less than 0.250 in. (6.35 mm) 
in length. Periodically remove carbon dust accumulation with a 
clean, dry, non-linting cloth. DO NOT use solvents as they can 
damage the non-metallic end shield. 

 

D-3. Brush Reassembly 

 

To replace brushes, pull out the brush/spring assembly. Insert the 
new brush assembly and screw on brush cap with offset slot 
screwdriver. 

 

D-4. Brush Cap Reassembly 

 

1.   Reconnect the drive to the power source. Test for proper 

operation. 

 
 

 

2.  Proper brush seating is required for minimal level of brush  

    

noise. Seat new brushes by running the motor with no load.
