After assembly, adjust pinion clearance. Pinion
clearance should
be0.02
to0.08
inch
(0.5
to2.0
mm);
if
not, check as follows (Figure
4):
A.
Connect starter to
a
battery. Close switch. This
will shift pinion into cranking position.
.
B.
Push pinion back by hand and measure pinion
clearance. If clearance does not fall within the
specified limits, adjust by adding or removing
shims located between solenoid and front
bracket. Adding shims decreases clearance;
removing shims increases clearance. Shims are
included with replacement solenoid.

TESTING ARMATURE
FOR
GROUNDS
Testing Armature
for
an Open Circuit:
Using an
ohmmeter, checkfor continuity between the commutator
segments.
If
there is no continuity (high resistance), the
segments are open and armature must be replaced.
Testing Armature fora
Short
Circuit:
Use a growler for
locating shorts in thearmature(Figure
6).
Placearmature
in growler and hold a thin steel blade (e.g. hacksaw
blade) parallel to the core and just above it while slowly
rotating armature in growler. A shorted armature will
cause the blade to vibrate and be attracted to the core.
If
armature is shorted, replace with a new one.
