Peugeot 308 Ring Gear

Grinding on start, the starter spinning without engaging, and a crunching noise as the pinion catches a damaged tooth. If it only happens at certain stop positions, the ring gear has wear on one section and the engine has parked the worn teeth at the starter.

On older Peugeots with a heat-shrunk ring gear, a skilled machinist can press off the old ring and fit a new one. On modern dual-mass flywheels, replacement usually means fitting the whole flywheel. We advise on your specific engine before ordering.

Pricing depends on whether it's a standalone ring or a full flywheel. Request a free quote through our form with your engine code and we'll price both options — often a used flywheel with a good ring gear is cheaper than a new ring alone.

Usually the starter pinion is meshing with damaged ring gear teeth, or the starter Bendix spring is weak and letting the pinion stay extended. We pull the starter to inspect both ring and pinion before deciding — replacing only one often means repeating the job.

Yes, in almost every case. The starter is usually what damaged the ring gear in the first place — a tired Bendix or solenoid slams the pinion into the teeth. Fitting a new ring gear behind an old starter invites the same failure within months.
