1.
Disconnect motor field coil connector from sole-
noid motor terminal and insulate it carefully.
4. Push pinion back toward commutator end to
eliminate slack.
5.
6.
Measure distance between pinion and pinion re-
tainer.
If clearance is not within limits of .010-.140 in.
(0.25-3.5
mm), it may indicate excessive wear of
solenoid linkage shift lever yoke buttons or im-
proper assembly of shift lever mechanism.
Check for proper assembly, and recheck gap. If
still excessive, replace worn or defective parts,
since no provision is made for adjusting pinion
clearance.

noid switch and negative (–) lead to solenoid
frame.

COMMUTATOR END FRAME GAP
To keep the ignition-proof and safety requirement,
the gap between the commutator end frame and field
coil housing must be checked. See specifications. If
the gap exceeds measurement when checked with
a feeler gauge, the end frame should be checked for
proper seating on the field coil housing. If properly
seated and still found to have excessive gap, the end
frame must be replaced.
