6. Solenoid
The solenoid must be conducting between Sand M
terminals and between S terminal and body.
7. Overrunning Clutch
If the pinion is worn or damaged, replace it.
8. Reduction Gear
Replace the reduction gear if it is worn or damaged.
9. Front Bracket
If the ball bearing or bushing is worn, replace the
bracket assembly.
10. Pinion Gap
A. Remove the connector from M terminal.
B. Insert the battery between the S terminal and the
starter motor (connect the positive cable of battery
to the S terminal), and the pinion moves out and
stops. Ughtly push the pinion back toward the ar-
mature to measure a pinion gap. If the pinion has
no standard gap, adjust by increasing or reducing
the adjusting washer between the solenoid and the
front bracket. Increasing the number of washers
reduces the gap.
CAUTION
In this check, do not apply the current for over
20
seconds to prevent switch coil overheat.
If the pinion does not move out, or if the pinion gap
is too large or too small, the shift lever has been
installed in a wrong direction or the magnet switch
is defective.
11. Pinion Shaft Thrust Gap
A pinion shaft thrust gap is an axial play of the shaft.
Adjust the gap to a value less than the standard
