NOTE: Bushings or bearings must not be cleaned
with grease dissolving agents.
Immerse all metal components in cleaning solu-
tion. Dry using a clean and dry cloth.
STARTER INSPECTION
Armature
NOTE: An ohmmeter may be used for the follow-
ing testing procedures, except for the one con-
cerning the shorted windings in the armature.
Check the commutator for roughness, burnt or
scored surface. If necessary, turn the commuta-
tor on a lathe, enough to remove grime only.
Check the commutator for mica depth. If the
depth is less than 0.20 mm (.008 in), undercut
the mica. Be sure that no burrs are left and no
copper dust remains between the segments after
the undercutting operation is completed.

Check the commutator out-of-round condition
with V Blocks and an indicator. If the commutator
out-of-round is more than 0.40 mm (.016 in), the
commutator should be turned on a lathe.
Check commutator outer diameter. If less than
specified value, replace.

Test for Ground Circuit in the Armature
Use growler test probes. Check between arma-
ture core and the commutator bars. If growler
lamp turns on, bars are grounded. If so, replace
armature.

Test Armature for Shorted Winding
When the armature is rotated in the growler with a
steel strip (hacksaw blade) held above it, the strip
will vibrate over that area of the armature which
has short circuit. Replace armature if so.
