Porsche 911 - Damaged Teeth on Starter

Owners of Porsche 911s (SR68X) commonly complain of starters with a severe toothache due to damaged teeth on the pinion gear. Before installing another starter, inspect the teeth on the ring gear. If they appear damaged, Porsche suggests replacing the original ring gear with a new ring gear (p/n 950 116 143 01) which is wider. The wider ring gear provides for better engagement of the pinion gear, and in turn, longer life for both the starter and ring gear.
