Just going over the new T I got, the one my Dad restored 40 years ago. Pulled the motor and trans down just to check it out. This what we found.
Dad sold the car to an engineer. He applied his skills to making a new drum. His only failing was to install only a half bush which has worn but it will see service again in the car. Thanks to Frank VanEkeran for assisiting with the teardown,the pullers and the workshop space.
wow! I wonder what steel he used. Or is it Iron?
I always thought that they should have holes in them to assist oiling. This one appears to be turned from a solid billet. When I fab them up I weld a piece of flat stock with holes in it to a piece of tubing. A lot less machining that way.
I doubt that the maker only installed half of a bushing. That bushing has a tendency to work it way out and is ground away by other gear teeth. I have seen several that are worn that way.
