Housing Inspection:
Permanent magnets are glued to
inside
of
the housing. Magnets must be secure and free
of cracks.
Brush
Inspection:
If
brushes are worn shorter than
1/4
inch
(6.35

and brush holder base.
If
there is continuity, replace
holder assembly. Check for free movement of brushes.
All
brushes should move freely
in
the brush holders.
Overrunning Clutch:
Inspect pinion
and
spline teeth for
wear or damage.
If
pinion gear is worn or damaged, inspect flywheel ring
gear also. Rotate pinion. It should turn free when turned
in one direction, and lock when turned in the opposite
direction.

cleaning solution will result in starter
damage.
Do
not clean overrunning clutch in liquid
cleaning solutions.
Solenoid:
Push solenoid plunger in and release it. The
plunger should return to its original position. While
holding plunger
all
the way in, check for continuity
between terminals
"M"
and
"B'.
If
there is no continuity,

Coil:
Use an ohmmeter to check for continuity
between brushes.
If
there is no continuity, the field coil is
open and must be replaced. With field coil mounted

Bushings:
If either the front or rear bushing show signs
of wear or damage, replace them. Bushing and rear
bracket are replaced as an assembly. Check armature
