Yank the head. Do it! I pulled the head of one stuck engine and the pistons were melted to the sleeves. Stuck free liquids would sit in there for a hundred years.

Pull the head and check it out. It is worth the head gasket and all the corn in Iowa to pull it.

You can wait for a Farmall forever...they will always wait you out. It will not free itself.

Pull the head and look in there. You may have to beat the pistons out with a sledge hammer.

If it sat for ten years, the rings are probably bad anyway.

Yank the head and look.

Just my...er....penny!

Get some rags and sop out that diesel fuel. It's not going to help because diesel is not a penetrant, and does not attack rust. At the very least, you need a good penetrating oil. People have their personal favorites; some use "Kroil," and I personally like either PB Blaster, or the Panther Penetrating Lubricant you can purchase at Massey Ferguson dealers. PB Blaster is available at Advance Auto Parts in spray cans and gallons. Get the gallon size.

Mostly, it's a soaking and waiting game. Soak, wait, rock the tractor in 5th gear. Soak, wait, rock the tractor in 5th gear. If it's not badly stuck, it'll break free fairly quickly. If it's badly rusted, pitted... you know, just plain nasty in there, you'll need to pound the pistons and sleeves out and replace them with new.

1. Don't start a fire in the cylinder. 2. Don't use the starter.

I have also heard of people using Coca-Cola to free a stuck engine.

Transmission fluid is what I used. You need to let it soak with dextron or something similar.
If it doesn't budge by bumping the starter I would use a piece of 2X2 oak or maple and give it an attitude adjustment with a big hammer. Not too hard, you do not want to damage the block.
The sleeve may come out with the piston. This happened on a Farmall A and I used a torch to
hear the sleeve and the piston came out. I only needed the rods since I was putting in a new sleeve kit. Need to be patient too. Hal

Let's not start a fire in the stuck cylinder unless you plan on pulling the sleeve. You will melt the o-rings.

Couple of suggestions.

1) Remove the connecting rod cap and bolts. From the bottom press the piston and perhaps the sleeve out with a hydraulic jack and oak 2x4. You can purchase one piston and one sleeve if needed.

2) If the piston is not on top or bottom dead center. 4x4 to fit cylinder. Hydraulic jack on top of the 4x4. Chains, across top of hydraulic jack, bolted down using head bolt holes. Press the piston down enough to get it moving.

PS. I have one engine that I worked on for a year trying to free up one piston. That was 3 years ago. It's still stuck.

Gene, the Farmall H uses dry sleeves, there are no o-rings.

James, I am guessing from your post that you have already gotten 3 of them out. So on that premis here goes.
1 roll the tractor just outside the shop. 2 be sure All combustiables are at least 20 feet away. If the fuel tank is not allready off....get it off and gone.
3 fill that piston half full with diesel fuel....set it on fire....let it burn itself out....put a splash of light oil around the cylinder walls. It should drive out fairly easly now. if not ....repeat.
I know guys that this is how they break loose engines that have been stuck for 25 to 30 yrs. Hope this helps. Just be very careful with setting the fire and other conbustiables nearby.
Later,
John A.

I picked up an H that sat under an oak tree for 25 years. It was stuck for how long I don't know. Diesel will not work and may even stop what I do. Fill the cylinders with tranny fluid. Let it sit a day or 2 and then hook a battery to the starter and just sort of hit and miss the hook up. Oh by the way 3 hours after I filled the cylinders on the H I have with tranny fluid I was driveing it.

Humm, James, Can you email me som e pics of the stuck pistons? Are they aluminum or cast iron? How rusty are the cylinder walls? Pitted? I use a 7/8 bar about a foot long and a 4 pound sledge hammer. That with caution and perseverance will get most of them.
