Triumph 650 transmission mods

I am taking the transmission out of a race motor to put a stock one in because I don't know what was going on with the one in there. why was is the mainshaft top gear shaved down to expose bushing? What would this do? and could this be why I couldnt turn over with the chain attached?

Both those gears are stock Triumph. The gear on the right is early unit 650, around 1968 Triumph lengthened the gear to better support the bushing and give the seal a steel surface to ride on.

I replaced my early transmission with a later one. I know the seal is a different size but can't remember if the access plate behind the clutch has a different sized opening as well. The trans that I got came with one and I just used it, cuz the guy I got it from made a point of letting me know that things were a little different. I can't remember checking to see if it was the same size or not. Maybe someone can clarify?

So the door is big enough to accommodate the later gear but I am not sure if it if there is a seal out there that will work...meaning maybe there is another door size that I need that has its own seal that fits it...

So here is a what if... What if I use the earlier gear mated up with the later trans? Is my laziness and impatience a recipe for transmission disaster?

(...and F-U, mate...haha.. I'm watching my daughter and need to be able to pick her up with clean hands...ala taking the gloves off. what you don't see behind me is the babygate in the doorway)
