Greetings all. My flywheel is the early 6-bolt type and the ring gear is pretty well beat up. At some point in its sordid past, the ring gear was replaced, so I figured that it was just a matter of removing the old one and replacing it with a new one. The problem is that it seems that all of the replacement ring gears are from the same manufacturer and the replacement I got is narrower (larger ID) than the one that was on the flywheel. The old one is marked “REPCOM” on one side and “270” on the other. The internet apparently has never heard of that. I need to find a ring gear that fits the machined diameter of the flywheel, which is around 308mm to the best of measuring ability. I do not want to replace the flywheel if at all possible. 6-bolt flywheels are like hens teeth and when one does surface, it is clear that the owner knows how scarce they are. So I am looking for ideas. One possibility is to have one custom made, but my Google-fu has not been up to the task of finding someone who will do it. Also, I don’t know the tooth pitch and profile which I assume would be needed for a custom gear. So I’m looking for brainstorm ideas. Thoughts?
Edit to add: The replacement gear that I have is CB132/10R which cross references to C4809. That seems to be the gear that all of the parts shops have.
