CLEANING AND INSPECTING

NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.
1. Thoroughly clean all components except the
armature and brushes in parts-cleaning solvent;
then dry with compressed air.
2. Inspect all threaded areas for damage or stripped
threads.
3. Inspect the brush holder assembly and brushes for
damage or wear. Using a caliper, measure the
length of the brushes. If brush measurement is less
than 10.1 mm (0.40 in.), replace with new brushes
and brush springs as a set.
4. Inspect the brush leads for cracks, wear, or
fraying. If any of these conditions exist, replace
with new brushes and brush springs as a set.
5. Inspect the rear cover bushing for wear.
6. Inspect the front cover bearing for wear.
7. Inspect the brass commutator end of the armature
for any burned spots or damage. If the commutator
is lightly burned or damaged, the armature must be
replaced. This is a molded commutator and
turning it down in a lathe should not be attempted.
8. Inspect the commutator end of the armature for
buildup in the grooves. Carefully remove any
buildup by undercutting using a thinly ground
hacksaw blade. Do not undercut any deeper than
the original groove which can be seen by looking
at the end of the commutator.
9. Using a caliper, measure the undercut. Maximum
undercut groove must be 0.2 mm (0.008 in.).
! CAUTION
Do not wash the armature and brushes in any
kind of solvent. Use only compressed air and a
clean dry, lint-free cloth.
! CAUTION
Do not use emery cloth to clean the commutator
as emery particles will become imbedded in the
brass commutator resulting in a short circuit.
Use only #200 grit sandpaper.
