8. Carefully pry the End Casting from the Frame. Be careful not to lose the wave washer between the End
Casting and the motor bearing. Note the following:
• The rotor’s bearing is a light press into
the top cap. It will come free fairly
easily, but care must be taken to not
skew the cap in the process.
• A very light tap on the side of the cap
with a plastic deadblow hammer should
be enough to loosen the cap enough to
begin prying with a small screw driver.
• Taking care not to damage the
aluminum cap, work the small screw
driver around the cap enough to be able
to get two medium sized screw drivers
in 180° apart, and then pry up on both
sides evenly.
9. Slowly and gently, lift the top cap up until the 4
brushes clear the commutator and rotor bearing.
10. Remove the nut from the terminal screw (D),
and lift the brush wire off the screw.
11. Slide the brush toward the center to remove the
brush and coil spring.
Note: When placing the coil spring and brush back
into position, note the direction the coil spring
faces so that it uncoils properly.
Note: You will need 4 temporary retaining pins, such
as straightened out paperclips. Have them
ready before completing the next steps.
