Yeah, that's essentially what the 3sx Performance guys that S2Zetec54 pointed us to did. I think it's all about finding a bearing that will take the input shaft and fit inside the dimensions of standard bearing/seal that would take the rpm and have good life. I was poking around and found this one (
https://bearingsdirect.com/25mm-bore-hk2520-needle-roller-bearing-25x32x20-tla2520z/) that seemed like a possible candidate. I would expect finding a seal would be a lot easier. Someone would have to take one apart to better re-engineer it but it shouldn't be too difficult.
I might try calling Richard tomorrow to see if he's up to it but don't make that an excuse for you not to call him if you have a mind. Anybody who calls him should reference the 3sx Performance page that S2Zetec54 linked earlier to make sure he gets the idea.
