how does a bendix work on a starter

by Gerson Frami Published 2 years ago Updated 2 years ago

A bendix is a device on a starter that uses a sprag clutch or overunning clutch to protect the starter motor. When you turn the key from run to start by some means either by solenoid or the pull from the starter winding the pinion on the starter motor shaft is engaged with the ring gear on the flywheel or flexplate. Click to see full answer.

The Bendix system places the starter drive pinion on a helical drive spring. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to wind the spring forcing the length of the spring to change, and allowing the pinion to engage with the ring gear.

What is a Bendix on a starter?

The starter motor itself has a device, called a Bendix gear, which engages its pinion with the gear ring on the flywheel only while the starter is turning the engine. It disengages as soon as the engine picks up speed, and there are two ways by which it does so - the inertia system and the pre-engaged system.
