What is the secret to removing the clutch drum. I cannot budge it. I have tried heat - nothing.
You'll have to remove the stop screw and use a puller that fits the two holes in the clutch hub, then it should be able to pull it of with a lot of force and some heat..
(The driven gear in the other end of the trans has been tougher to pull in my limited experience since they're hardened and will loose strength if heated too much)
You need a puller that will pick up the two holes in the drum. You can get an original or repro puller, or you can use a modern puller and place bolts in the holes to give you something to pull on. You can likely grind the ends of a modern puller so it will bite the holes. I have pulled drums on 3 transmissions with the modern pullers I have.
I assume you have removed the setscrew.
Yeah we removed the set screw. We have straightened several J bolts - heated it red, and it has resisted. We finally figured out we were using the wrong swear words, one we got it right it did finally give up. We ended up putting a couple of bolts in the holes and used an outside jaw puller.
Doug, I put pressure on it with the puller and I use a brass shaft about six inches long and hit the side of the base around the center shaft and you will hear it pop then put more pressure on it and smack it again after that I have always been able to finish using the puller to get them off, some are really tight!
YOU are in for a struggle. They are nothing but doggone tight! I used a really strong snap on puller with the two shackles with a 24 inch breaker bar, added some heat and, BANG !!!! she let go. Youd swear the drum was gonna break but its some good vanadium steel. When in doubt improvise. I also broke several Home made J bolts and assorted sundrie of pulling stuff. If it went together itll come apart! BTW... oil the threads on the puller. ws
