Re: Bendix drive gear pin
That's to provide a controlled amount of friction. It is important.

Keeps the starter gear from randomly getting into the ring gear while the engine is running.

Re: Bendix drive gear pin
It is called an "anti-drift" pin and holds the drive gear in its quiescent resting place so it does not vibrate back down the threads into the ring gear.

Re: Bendix drive gear pin
When the starter is powered up, the high torque of the motor forces the spring loaded pin upward out of the groove and allows the drive gear to screw down the drive sleeve, approach and engage the ring gear to turn the engine over to start. The ratio of the Bendix drive gear and ring gear is a ratio of 12 to 1. Hence the starter 12 foot pounds of is multiplied by 12 to apply 144 foot pounds of torque to the crankshaft for starting.
