Armature
Check external condition of armature for scoring or other
damage. Measure shaft distortion with dial indicator. Replace armature
if shaft distortion exceeds .004" (.10 mm).
Commutator
1) Inspect commutator for roughness, grooves, burns or
pitting. Sand lightly with 500 grit sandpaper if necessary. Check
commutator for out-of-round and mica insulators undercut to a depth of
.020-.031" (.5-.8 mm).
2) If necessary, commutator may be turned less than .04" (1
mm) from original size and mica undercut. Replace if excessively worn.
Field Coil
1) Check field coil continuity by connecting test probe of
circuit tester or an ohmmeter to the field coil positive terminal and
brush holder. If circuit is open, replace field coil.
2) Check for grounding of field coils by placing one probe of
circuit tester on starter housing and other probe to field coil
positive terminal. If little or no resistance, field coil is grounded
and must be replaced.
Overrunning Clutch Assembly
1) Inspect pinion assembly and sleeve. Sleeve should slide
freely on armature shaft and spline. If damage or resistance is noted,
replace assembly.
2) Check pinion and flywheel teeth for excessive rubbing or
damaged teeth. Replace as required.
Pinion Gear Clearance
The clearance between the pinion gear and pinion stopper

collar should be .02-.08" (.51-2.03 mm) on Mitsubishi starters, when
solenoid is engaged. Adjust as necessary by changing shims between
solenoid and starter yoke.
