Don't be too impressed, they set it up wrong, eventually the clutch walked on the bearings causing alignment issues.
There is nothing to hold the bearings in place with centrifugal forces the boar walks (slips) on the bearings
Yes the bearings was a good Idea but they installed em wrong
Only 2 bearings are needed, one on each side of the boar
The bearings should be installed like the bearings are installed in a wheel hub
There should be a ledge inside the boar on each side for the bearings outside edge to rest on
A spacer in between the two bearings supports the inside race of the bearings.
Much easier to just use an "Oilite bushing"
I figured out, in the end I made four counts and getting the bell machined would come to cost me a fortune; I'll stick to an Oilite bushing, it requires soaking only every so often:
Plus, if I were the type of person that would have no patience to wait for it to soak up overnight, I'd keep a bushing dipped in oil while the other is in use.
I just took off my bushing and I left it dipped in oil, I'll give an update tomorrow
