1. Component Repair
Disassembly
1. Scribe or center punch locating marks in the
commutator end head and the frame. Although
locating marks are not always necessary because of
locating pins in some motors, they can save a lot of
time when the motor does not have locating pins.
2. Remove the commutator end head retaining screws.
Most motors have a slip fit bearing at the commutator
end, and the end head can be removed with very little
trouble.
3. Remove brush holding plate screws and remove plate
to replace brushes. Remove each brush from brush
holder and inspect brushes and commutator for worn
condition and uneven wear.
4. The brush springs may be checked at this time for
proper tension.
5. Separate the armature and drive end head as an
assembly from the frame and field coil/stator.
6. Separate the armature from the drive end head. This
operation is usually done by pressing the armature out
of the drive end bearing. Remove with puller.
When a puller is used, protect the end of the armature
shaft with a nut or a thick flat washer. If the shaft,
coupling, or spline is damaged when removing the end
head, the armature or the drive spline usually has to
be replaced. Use caution, and
DO NOT
damage the
armature.
7. Remove bearing from armature or end head.
