Title: Ring gear teeth
Post by: Vincent on June 23, 2019, 04:13:14 PM: From what Iï¿½ve found out, the ring gear on my 1953 CJ3A should have 124 teeth. The one I just removed from the flywheel has 129 teeth. It had sat in a field for 20 years before I got it and it looked like someone had changed it to 12 volts. Would that require a different starter, and also replacing the ring gear? I want to restore to original 6 volt. So do I now get a 124 tooth ring gear and the appropriate starter, or am I wrong and this could be the original ring gear with 129 teeth?
