Pinion Gap

NOTE: DO NOT apply voltage to starter assembly for no more than 10 seconds.

With starter on a bench, disconnect terminal connector from starter solenoid "M" terminal. See Figure .
Apply battery voltage to solenoid "S" terminal and ground starter motor body. Pinion will eject.
Measure pinion gap between pinion and stopper. See STARTER SPECIFICATIONS. See Fig 1
If pinion gap is not within specification, make adjustment by increasing or decreasing number of gaskets between solenoid and drive housing. Gap will decrease as number of gaskets is increased. See Fig 2
