So heres the problem. We need to get the tranny back off because we didnt put the clutch together right. So we took all the bolts out and tried to put it off and it wouldnt come off. So we figured out that its catching on the clutch plate or so we think. So we unbolted the pressure plate trying to see if that would help which it obviously didnt from the pictures. So now I need some help anyone know what I can do to get this damn transmission seperated from the engine. How I can get it to stop catching or how to push the parts of the clutch out of the way or any other advice. Thanks Richard
 
The inner race of the pilot bearing is probably friction welded to the nose of the input shaft after the bearing failed. You will need to pull the outer race to separate them and this will take some extra effort, like two 6 ft pry bars on either side of the tranny
 
Well we lubed the heck out of it the other day when we put it on so I don't know how it would be friction welded. I mean its only been in a week and hasnt done anything but sit in place. But maybe we'll try the good old brute force some more then. Thanks
 
What I was able to do to separate a 3 speed tranny from the bellhousing was use the tranny bellhousing bolts BETWEEN the tranny and bellhousing to, gently but with significant force, push the two apart. It seems safer to me then the prybar route because you don't want to bend any input shafts or anything else.
Just thread the bolts into the tranny or bellhousing in such a way that the heads are between the tranny and bellhousing. Then just give each bolt a 1/2 turn as you go round and round until they pop apart!
 
I'm not sure if I follow you here I think I'm just confused maybe. Which bolts are you talking about? The only ones that I know of between the tranny and bellhousing are the 4 that hold it on, and they are already out.
 
you aren't gonna like this.....


David and i were seperating a tranny/engine out of a recently restored '71, so far all bolts has eased out, things could not have been easier.

Never got the transmission out. Like PH said, the input shaft had welded itself to the throwout bearing. we even went so far as to strap the engin to a 2 foot square concrete post and pull on the tranny with a 350'd 40. (there is video of this on the board somewheres) in the end we just destroyed the bellhousing with a BFH and to this day the bearing is still welded on the input shaft with the clutch parts sitting there.


Good Luck :D

How does the input shaft weld to the pilot bearing? When you use the term weld I think heat and melting and that sort of thing and this has done anything but sit in place for 7 days.
 
Yes, I'm talking about the four bolts that normally hold everything together. What I did was cock the tranny from the bellhousing so that the bolts could be inserted with the head BETWEEN the tranny and bellhousing (like a ram to push the two apart). ie: thread the bolt ONLY into the threaded hole, DO NOT put the bolt through the unthreaded hole as you normally would. Then reorient the tranny and bellhousing. At this point the bolt heads should be in the space between the tranny and bellhousing, not holding the tranny and bellhousing together. That way when you "loosen" the bolt you push the tranny and bellhousing apart! It should give you about 2-3" of movement which will hopefully be enough.
I did it with the pressure plate still attached to the flywheel.

I've seen the same problem, and used the PinHead method.

You're gonna need another clutch disc.
