ok

at the end of the starter motor is a piece called a bendix drive. it is a one way clutch that engages the flywheel when the starter is activated. the one way clutch does fail and causes it to kick out early.

2 possible repairs.

1. remove the starter motor and disassemble and replace the bendix drive itself.

2. replace the starter motor.
