First time I put the input drum together, I couldnt get the snap ring seated on the forward clutch because I used cotton based towels and it wouldnt let everything seat properly with a wad of cotton towel sitting at the bottom. Seals were easy for me except for that. The lo/reverse spring on the 60e loads the whole system, so of course, its the toughest/highest spring rate, and of course, they are going to put it at the bottom of the case where its most difficult to get to. At first I attempted the press with some welded flat bar to make an upside down 'u'........ that cost me $24. I saw a guy on pt.net make that type of tool to remove the spring, that worked mo betta.
