Replace the O-rings [A] with new ones.
Install the end cover [B] and tighten the through bolts [C].
Torque - Starter Motor Through Bolts: 5.0 N·m (0.51 kgf·m,
Measure the length of each brush [A].
If any is worn down to the service limit, replace the brush

Commutator Cleaning and Inspection
Clean the metallic debris off the between commutator
Do not use emery or sand paper on the commutator.
Check the commutator for damage or abnormal wear.
Replace the starter motor with a new one if there is any
damage or wear.
Visually inspect the commutator segments for discol-
Replace the starter motor with a new one if discoloration
Using the × 1 Ω hand tester range, measure the resis-
tance between any two commutator segments [A].
Special Tool - Hand Tester: 57001-1394
If there is a high resistance or no reading (∞) between any
two segments, a winding is open and the starter motor
must be replaced.
Using the highest hand tester range, measure the resis-
tance between the segments and the shaft [B].
If there is any reading at all, the armature has a short and
the starter motor must be replaced.
Even if the foregoing checks show the armature to be
good, it may be defective in some manner not readily
detectable with the hand tester. If all other starter motor
and starter motor circuit components check good, but
the starter motor still does not turn over or only turns
over weakly, replace the starter motor with a new one.
