Every time your emergency standby generator receives a start command, a high-torque electric or pneumatic starter motor flings its drive pinion forward to mesh with the massive flywheel ring gear. It is a brief, violent mechanical handshake transferring immense rotational force to bring a multi-ton engine up to firing speed.
When ring gear teeth become chipped, mushroomed, or severely worn, your starter motor will grind uselessly against the flywheel, failing to crank the engine when you need it most.
Preventing Tooth Damage and Misalignment
- Check Starter Pinion Depth: Improper engagement depth between the starter drive and ring gear causes premature edge-chipping on the gear teeth.
- Thermal Shrink-Fitting: Replacing a ring gear requires precise thermal heating procedures to expand the ring evenly before seating it squarely onto the heavy flywheel shoulder.
