FARMALL A BELLHOUSING MOTOR SEPARATION

PATRICK MCDUNN · Apr 3, 2010

I'am trying to take the bellhouseing and motor apart on my 1948 Farmall A because now I see something has made a nest in there and the clutch won't disengage when I press on the petal. We have everything unbolted and the motor and bellhousing are about 3/8 of a inch apart. but won't come apart any farther. can some one tell me what I'm missing on taking this apart.

You're probably NO missing anything, the pilot shaft splines are simply rusty and sitcking in the clutch disc.

It shouldn't take anything more than two quick eyeball checks to make sure that everything between the front and back are disconnected. Fuel line and choke linkage on the left, wiring on both sides, governor linkage on the right, hydraulic manifold if you have one. And the steering. Other than that the only thing holding you back might be the dowel pin(s) between the torque tube and the crankcase, which have a tendency to make things want to come of really straight. If there's nothing else hindering things, and little back and forth, up and down fiddling with a prybar between the two ought to get hem apart.

Last thing, and it's not a small one. Dou you have the front steering arms and wheels blocked/wedged so that they can't turn? If not do. The front wheels will will turn and fold if not held in place when the tractor is split behind the motor. It could be the torque/twisting effect of them trying to do that that could be binding on the aforementioned dowel pins that is binding things up.

Use some pinch bars on each side to see if it will move. Make sure you have the engine supported. Hal

Since you know something is sticking within the clutch, maybe a lot is sticking. Makes me think Bob is on the right track. If it won't come apart following the suggestions already made, you may need to unbolt the pressure plate from the flywheel. I've never had to try it, but think you can do it through the hand hole in the bell housing. If the pressure plate is the type where 3 bolts are used to hold the springs compressed, move every other pressure plate bolt to the open holes then remove the 3 remaining bolts. If you can do that, the pressure plate and clutch disk will stay in the bell housing when you split it. Then you can get at the disk to remove it from the splined shaft.

My son had an old WC Allis that mice built a nest in the bellhousing & pi$$ed on everything causing everything to rust together. We were able to get it about as far apart as you have. We tried large pry bars to no avail. Finally, in desperation, we sprayed a can of PB Blaster up in it & let it sit a couple days. Then we parked another tractor in front of it & hookd a chain hoist between the two. Between the chain hoist & using pry bars we were finally able to get it aprt but I was binging to wonder for awhile. If you try something similiar just go slow & cross your fingers something doesn"t break.
