Figure 9-21, Pinion Clearance Adjustment
Pinion Clearance Adjustment
This check must be made with the starter removed from the engine. It is rare that the pinion has to be
adjusted, however if the wear pattern on the pinion teeth indicates that the pinion is not engaging the
flywheel ring gear at the proper position, proceed as follows:
1. Disconnect the field coil connector from the solenoid motor terminal and field frame on the
starter to prevent the starter from turning.
2. Connect a test lead from the positive (+) terminal of a 24 volt battery to the solenoid switch (“S”)
terminal. Connect another test lead from the battery negative (–) terminal to ground on the starter
or solenoid frame.
3. Momentarily flash a jumper lead from the solenoid motor terminal to the solenoid frame or
ground terminal. The drive will now shift into the cranking position and remain so until the bat-
tery is disconnected. Jumping for more than a few seconds will damage the solenoid.
4. Push the pinion back towards the commutator end to eliminate slack movement.
5. Measure the distance between the drive and the housing. The distance should be between 0.330"
and 0.390" (9.3 to 9.7 mm). See Figure 9- 21.
6. To adjust the clearance to the proper amount, remove the plug and adjust the nut on the solenoid
plunger rod as necessary to obtain the proper clearance. After the correct clearance is obtained,
install the access plug and gasket in the shift lever housing. Incorrect pinion clearance adjust-
ment can cause the solenoid contacts to close with the pinion outside the ring gear and lead
to pinion and ring gear damage.
