SWITCH ASSEMBLY OPERATION
1) Connect terminal S of switch ASSY to positive terminal
of battery with a lead wire, and starter body to ground
terminal of battery. Pinion should be forced endwise on shaft.
With pinion forced endwise on shaft, starter motor can some-
times rotate because current flows, through pull-in coil, to

motor. This is not a problem.

2) Disconnect connector from terminal M, and connect
positive terminal of battery and terminal M using a lead wire
and ground terminal to starter body.
In this test setup, pinion should return to its original position
even when it is pulled out with a screwdriver.

PINION GAP
1) With pinion forced endwise on shaft, as outlined in step 1)
above, measure pinion gap.
Pinion gap:
0.5 - 2.0 mm (0.020 - 0.079 in)
10
If motor is running with the pinion forced endwise on the
shaft, disconnect connector from terminal M of switch ASSY
and connect terminal M to ground terminal (-) of battery
with a lead wire. Next, gently push pinion back with your
fingertips and measure pinion gap.
2) If pinion gap is outside specified range, remove or add
number of adjustment washers used on the mounting surface
of switch ASSY until correct pinion gap is obtained.
PERFORMANCE TEST
The starter should be submitted to performance tests
whenever it has been overhauled, to assure its satisfactory
performance when installed on the engine.
Three performance tests, no-load test, load test, and lock test,
are presented here; however, if the load test and lock test
cannot be performed, carry out at least the no-load test.
For these performance tests, use the circuit shown in figure.
