Remove thru bolts
Note: Do not use any metallic oxide paper or emery cloth,
as metallic oxide or emery will become embedded in
commutator causing rapid brush wear.

If armature is suspected to be defective, a new armature
should be tried in motor.

Separate motor end cap from motor housing.
Push motor armature out through bottom of starter
housing, taking care to slide plastic mounted terminal out
of motor housing along with end cap, Fig. 98.
If proper testing equipment is available, check suspected
armature to determine if it is defective.
Starter motor armatures have very low resistance, usually
below detection on available multimeters. To check for
shorted armatures, a piece of equipment known as a “growler”
may be used. If this equipment is not available, a known good
armature should be tried and performance rechecked.

must be corrected, or poor starter motor performance will
result, Fig. 99.
