This is a bit of a stretch for me to remember, I know with the 904 front drum, you have to pay attention to the clutch clearances, from memory what Jim said about the clearances was basically on the money. 5 clutches in the front drum is a must in anything over say 450-500ft/lbs in a 904, There are a couple of other things , but I will have to go through my notes from when we did our last trans. I will definately be keeping a close eye on this thread, and hopefully it makes it to the archives.
