Review on High-Performance 12V Starter for Ford 8N, 9N, 2N Tractors - Upgraded with Drive Bendix, Reliable 12 Volt Ford 8N Starter: 3109 SA546 8N1100R 8N11001R 1831810 8N-11001 9N11001 9N11002 150-025-12 SFD0191 8N-11002 SA-546 1939-1952 by Cris Drew

I installed and used my new starter 10 times and then the bendix got stuck and wouldn't move the starter gear. I've read several other one star reviews and it looks like the same thing happened to them. When this happens, the starter essentially just spins (possibly lapping the flywheel a little), but doesn't spin the engine. It is very sad that the quality of design and materials has dropped so much in this country.
