Farmall A front pully and clutch

Wed Jul 12, 2006 9:31 am

Hey guys, I'm working on restoring my grandpa's farmall A. The pistons are stuck in place. I've soaked them for several month, but finally decided that I have to hammer them out. I have the engine block removed from the tractor. I'm now trying to figure out how to remove the clutch and front pully from the engine block. Any good ideas?

Steve, the sleeves in an A or wet sleeves, so why not just knock the lseeves out and get a rebuild kit. The crankshaft pulley is pressed on like a cub, if you do a search for puller you will find instructions and a puller. the one differnece is there is not a threaded hole in the shaft as there is in a cub.

While the tractor was sitting for several years, the engine block froze and cracked. I have since aquired another block. I was hoping to see what all is salavagable from the stuck engine. I'm wanting to reuse the clutch, pully, crankshaft, and maybe pistons/sleeves. Tractor was not smoking when it was parked years ago, but I'm willing to replace pistons/sleves if I need to. I was guessing that the front pully was pressed on similiar to a cub, but I wanted to make sure before I started pulling on it. I've seen many of the posts concerning a cub pully and will build a similar puller. My other question is how to remove the clutch. Is it pressed on also, or is there a bolt or something that I'm missing?

Very early A's had a setscrew in the pulley, so you better check for it.

Are you asking about the main engine clutch? Held on with a circle of bolts, just like . . .

Well, I got the clutch removed today, and I've started working on making my pully puller. Any body know the size of the bolt that I need to screw into the shaft?

Press out the pistons and sleeves. Heat the piston and sleeve in the bbq pit. When nice and hot try pressing the piston out of the sleeve.

If it works you may be able to use the piston, sleeve and rod. If not -.

Steve, I dont't think Teh shaft on an A is threaded the way a cub crankshaft is.

I have pulled them off a super A and a B and they both had threads for 1/2" coarse.
