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.
WARNING
Failure to disconnect the motor wires from the
power source before inspecting or replacing
brushes can result in personal injury.
STEP #2 – Remove Two Brush Caps
Refer to Figure 1 for the location of the two brush caps. The plastic brush caps
are held in place with screw threads. Unscrew the brush caps using the largest
possible slotted screwdriver tip and remove them.
CAUTION
The brush caps are made of plastic and are installed
tightly. Using a small screwdriver to remove them
will damage the slot.
STEP #3 – Remove Brush Springs
After the brush caps are removed from each side
of the motor, the brush box assemblies can be seen
inside each of the two openings. The brushes are
retained by constant-force, roll-type springs. The
springs must be removed before the brushes can
be removed. To remove a spring, first locate the
flat part of the spring, which points outward (see
Figure 3).
WARNING: Wear safety glasses!
