I just did the same clutch in a ED-40. When you look in there, down the axle with the housing and
reduction gear removed from the tractor, there are 6 socket head capscrews, these take the clutch
off of the brake drum and you can remove it easily. The CA manual has information. So does the
Unofficial Allis forum. One thing the manual doesn't say is when the new clutch is together you
check the amount of clearance for release. If it is excessive you bolt the part with the 3
fingers where the six capscrews go to a milling machine table and take some off, the clutches
work better without excessive clearance here. On the other forum there was good pictures. The CA
manual has a good exploded view too and specs for the springs. Mostly you clean and inspect,
replace worn balls or ramps they roll on, warped parts, and worn clutch disc. The clutch disc is
supposed to be close to .193 thick, if it is not close that could be the problem. Or the springs
are weak, broken, or the self energizing balls and ramps pitted or out of round, as I said it is
mostly cleaning and inspecting. Same for the release mechanism that the lever actuates. You need
about 2 1/2" of free play in he lever too, if you have none this isn't going to help it either.

in the title so I don't delete your message with the rest of the junk. Tom
