STARTER SERW1CE INFORMATION
The Mitsubishi starter motor is a serviceable
component and can be disassembled for
repair.
Replaceable components include the solenoid,
overrunning clutch, brushes, brush holder,
armature frame and magnets, overrunning
clutch housing and the planetary gear drive
assembly.
Certain precautions must be observed when
servicing the Mitsubishi starter.
• The starter must not be roughly handled.
Hammer blows and similar mechanical
shocks can damage the unit.
• Be sure test connections are correct when
checking starter performance. A wrong con-
nection will damage the starter magnets seri-
ously enough to require replacement.
• Ensure cleanliness during starter repair.
Metal chips are attracted by the starter mag-
nets. Be sure all chips are removed with com-
pressed air and clean shop towels. Chips in
the armature frame, planetary gears, or over-
running clutch can cause premature wear.
• The starter armature, armature frame, over-
running clutch, planetary gears, solenoid
and rubber parts may be cleaned with dry
cloths and compressed air. Do not use liquid
cleaning agents on these components. All
other starter components may be cleaned
with commercially available solvents.
• Never clamp the starter motor armature
frame in a vise. Doing so may damage the
frame and magnets. Use only the mounting
flange on the overrunning clutch housing for
clamping purposes.
