So my 263XHD finally crapped it's pants, started to clunk shifting on the fly which progressed to a grinding then even louder bang, I assume this is because my rear seal was leaking and I was lucky to have 3/4 of a liter left when it first happened. I'm guessing shift forks/pads, maybe even synchros or the blocking ring. Trying to find rebuild information on this case online is pretty hard, I was wondering if anybody had any idea where to find some sort of repair guide other than the Helm manuals?
