Has anyone ever seen a chewed up ring gear with mushroomed over teeth, like the ones commonly seen on old tractors with 6 volt systems?
Some of them are messed up so bad that even a new drive gear has trouble engaging and quickly fails.
Most often seen on a neglected starter with poor connections that can not deliver enough power to crisply engage the drive and usually associated with a loose starter, excessive play in bearings or bushings, bent armature shaft, corrosion etc.
Often when you hook up one of those starters to a 12 volt battery and correct any of the problems listed above it does not take long for that firm engaging drive to clean up all of those burrs and create a real nice pattern when you check the mesh to the ring gear, this is assuming the starter was properly installed and shimmed as required.
