The hole sizes I had were the measurements from my original Trackmaster side plates. The bearings were really tight in them too but I kept their sizes to try out. They really did need to be opened up a little though.

Yeah I'm always a fan of making the holes smaller and sneaking up on it on my own stuff. Customers just don't like it much haha

After the feedback I adjusted the holes to the sizes I typically use. I don't like to modify customer files when supplied but once I sell to others I definitely try to add my $.02 haha

I forgot it was for rc10, lol...it worked out well considering!

When was this transmission available?

Did Trackmaster make a direct drive transmission too?

Mid to late 80s

Hardened steel Factory Works outdrives drilled to size with a carbide drill bit and installed. It's nice to have this transmission complete.

Probably too high of RPM and I eased it through in small increments on my drill press.
