Install and tighten the two through capscrews.
Install soienoid plunger in lever. Secure solenoid to
front bracket with two machine screws.
Install wire lead to the terminal
"M"
on solenoid.
After assembly, adjust pinion clearance. Pinion
clearance should be
0.020 to 0.080 inch (0.5 to
2.0 mm); if not, check as follows. See Figure 5.
A.
B.
Connect starter to a battery, as shown in
Figure 5. Close switch. This will shift pinion into
cranking position.
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.

Inspection and Testing
Inspect the starter components for mechanical defects
before testing for grounds or shorts.
Testing Armature tor Grounds: Touch armature shaft or
core and the end of each commutator bar with a pair of
ohmmeter leads (Figure 6). A low ohmmeter reading
indicates a grounded armature. Replace grounded
armature.

FIGURE 6. TESTING ARMATURE FOR GROUNDS
Inspecting tor an Open Circuit in Armature: Using an
ohmmeter, check for continuity between the commutator
segments. If there is no continuity (high resistance), the
segments are open and armature must be replaced.

Testing Armature tor a Short Circuit: Use a growler for
locating shorts in the armature. Place armature 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 (Figure 7). A shorted armature wi
cause the blade to vibrate and be attracted to the core. It
armature is shorted, replace with
a
new one.
