Testing Field Coilsfor Open Circuits:
Place one prod
on the connector and the other on a clean spot on the
brushholder (Figure 38). If continuity is good, the
field coil is good. Check all brushholders in the same
manner.

Brushes:
When brushes are worn more
than 0.3 inch, replace them. Figure39shows the wear
limit.
See that the brushes move smoothly

Inspection
for
Brush Spring Tension:
Measure brush
spring tension with a tension meter (Figure 39a).
Push the brush into its holder and take the reading
just as the brush slightly projects from the brush-
holder. On a new brush thespring tension should be
49 to 59 ounces (1.37-1.65 kPa) for
RCCK
engines
and 29 to 38 ounces (0.81 to 1.06 kPa) for MCCK
engines.

immerse bearing equip-
ped parts in cleaning fluid.
Clean wifh a brush dipped in mineral spirits.
Donof clean overrunning clufch

or
liquid cleaning
solufion. Washing the clufch will cause the grease
to

out.
Apply20 weightoil to

Use grease sparingly on solenoid starter shift
lever pin, joint
of
shift lever and plunger, plunger
and spacing washers at end
of
the shaft.
Use spacing washers to adjust armature end play
of
0.004
to
0.020
inch (0.102 to 0.508 mm).
When assembling starter to engine oil base, do
not draw the mounting bolts up tight. The gears
should have 0.004 to0.007 inch backlash. Tap the
starter in or out from the oil base to adjust. Then
tighten starter mounting bolts to
