6. Solenoid
The solenoid must be conducting between S and
M
terminals and between the 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.lnsert the battery between the S terminal and
the starter motor (connect the positive cable
of battery to the S terminal) so the pinion
moves out and stops. Lightly push the
pinion back toward the armature to measure
the 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.

Standard Value

(0.0197 to 0.0787 in.)
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
value by the adjusting washer between the center bracket and the reduction gear.
