Hi Folks, I just bought a 1947 Farmall M and the engine is stuck. I have been putting Mysitic Mystery Oil with a mix of transmision fluid and a penatrent. Three cylinder have leaked by but one has not flowed ne thing. I have waited for almost a week now rocking the tractor back and forth in gear hopeing the free it. Any Ideas are more than welcomed. Thanks

I was going to suggest what John said about using diesel fuel. Kerosene might be easier to light off. Be sure to remove anything flammable and the hood and gas tank. Only do one cylinder at a time. Have the rod cap removed on the cylinder you are heating. The heat should expand the metal enough to free it up. Then tap the rod with the oak agaist it and use a big hammer.

I didn't use heat on a Farmall A that was stuck. I pour that tranny juice in it and smack the rods with some oak and a hammer. The piston and sleeve
came out on 2 of them and just the piston on the other 2. I then drove out the old sleeves. The sleeves are pressed in your engine and are called dry sleeves. The A, B, C and Super C used wet sleeves and aren't pressed in. Hal

I've got an H that has been soaking for at least 3 years now. Finally was able to remove 2 of the pistons. The other 2 will have to be pressed out with the aid of a heavy duty hydraulic press, and I imagine the sleeves will come out with the pistons.

linemanfarmer, IMO one week of soaking is just not long ennough. I take it that you want to get it up and going fairly quickly. I would have soaked te cylinders for at least 1 month before messing with it. But anyway thats another topic.
So for now remove from the tractor and immediate area the fuel tank and any other combustiables! next roll the tractor outside!
Fill the stuck cylinder with DSL, then pour in a splash of gas then set the mixture on fire! and let it burn it's self out, Hopefully the piston isn't at the top, more toward the bottom of the stroke. So there is a goodly amt of DSL to burn. it will heat the cylinder up enough, and break down the rust so the piston can be driven out. If te piston is more near the top then you may have to do it a few times to build upenougt heat to do any good. Hope this helps.
Later,
John A.

If that cylinder has not been full of water for a long period of time this may work for you.Remove valve cover back the valve adjuster off so that the valve are closed.
Take a old spark plug break the porcelain out of it. braze a fitting on it for air.put a 50/50 mix of anti freeze in cylinder put air on it leave it for ever amount of time you wish.Anti freeze well pentrate the corrosion the air will push it down through.water makes rust.(corrosion) water will dissolve it.If real bad it well not work.

Useing the rear tire to rock it loose doesn't put out enough torque to do much unless its not stuck badly. Pull the plugs and then put a battry on it 12 volt works best. Then use short fast hits of the starter button. If that doesn't brake it loose then you will need to pull the head. Another thing you can try is blow out that cylinder to clear it and then fill with turpentine, use nothing else but turpentine, not paint thinner but the good old stuff. If it doesn't give then its head off time. MMO oand other stuff doesn't work in my book only tranny fluid or turpentine, I NEVER use any thing else and have only had one that didn't come loose out of more then 10 engines

Well, not too long ago me and dad bought a complete engine from a Farmall 350. First off, I pulled the manifold off, and found solid flakey rust inside the #3 and #4 exhaust outlet, and first thought was, boy, we are gonna have a problem. I pulled the head and found that I think 1 and 3 cylinders were not stuck, but I think 2 was slightly stuck, but #4 was totally stuck. It had so much rust in the cylinder, due to no exhaust covered and exhaust valve was open, that you couldn't even find the piston without cleaning the best you can all the flakey rust that was on top of the piston. She wasn't going to budge, and I relized that. I pulled the pan and found that the crank was in an akward position because I wanted to remove the crank and drive the pistons and sleeves out of the engine. I looked around, didn't even soak the cylinders, and found my fence post driver, and though, hmm...if this fits in the cylinder, maybe I can get the sleeves to slide just enough to get the rod caps off, and remove the main caps, and remove the crank. Well, I put the driver in #2 cylinder or the deepest cylinder and drove as hard as I could and it did slide the stuck cylinders enough and I removed the crank. Well, I found a 60lb rod that would fit between the rod and cylinder wall from below the piston and drove each out. It got a little tricky with the #4 which was totally stuck, but ended up driving the whole sleeve out. It took about 4 hours to get a complete stuck engine apart, but everything checked out ok and it's in the process of being overhauled with a stroker crank and put in my 1940 Farmall H. If I was you, pull the head and the pan, and find out exactly what your dealing with. If stuck in the cylinders, I would do what I did with my 350 engine. Best of luck to ya!!

I would do as Red suggested on pulling the head and dropping the pan. You may need to remove one of the rod caps and use a piece of 2X2 oak and a big hammer and try driving the piston out. I would lossen all the rod caps and mains too. You need to be patient if they don't move on your first attempt. Keep soaking with that tranny juice. Hal

Depending on how long it has been stuck- I would pull the cylinder head and see what is going on in there. Could be rust, could be a stuck lifter, could have bent rod. At least drop the oil pan, pull the valve cover and remove the rocker assembly to get a better look.

Some guys have had luck pumping the stuck cylinder full of grease through the spark plug hole- you"ll have to make a fitting to get it to work.. and then pull the head to remove all the grease!
