Bodine 24A Series Quick Start Manual

Inspecting and Replacing Brushes in Bodine Type 24A Permanent
Magnet DC (PMDC) Motors or Gearmotors
The permanent magnet DC (PMDC) motors and gearmotors manufactured by Bodine Electric Company are
unique compared to other DC motors and gearmotors in many ways. This is because the primary objectives in
the design of all Bodine products are long life, quiet operation, and no lubricant leakage. The long life
carbon brushes in your Bodine 24A motor or gearmotor are subject to routine wear and will need to be
inspected and replaced periodically to provide continued optimal operation of the motor or gearmotor.
Installing bushes and springs correctly is critical. Incorrect installation can cause brushes to wear faster, or
ultimately could damage the product.
By following these instructions when inspecting and replacing the brushes in a Bodine type 24A motor or
gearmotor, the user can be assured of long brush life, and desired motor or gearmotor performance.

TOOLS NEEDED:

Medium size
slotted tip
screwdriver
STEP #1 – Disconnect Power
Disconnect the motor wires from the power source before working on the motor. The motor or gearmotor should be
cooled off to room temperature.
Failure to disconnect the motor wires from the power
source before inspecting or replacing brushes can result
WARNING
in personal injury.
STEP #2 – Remove Two Brush Caps
Refer to Figure 1 for the location of the two brush holders. The plastic brush caps are held in place with screw threads.
Unscrew the brush caps as in Figure 2 using an appropriately sized slotted tip screwdriver and remove them.
Fig

The brush caps are made of plastic and are installed
CAUTION tightly. Using too small a screwdriver to remove them
