Water started the prob, fill the cylinders with this, heat it if you can, but leave it for a day, rock the machine in high gear! drop the pan and spray the cylinder walls with anything but wd40! Even more water! Now the rings are going to be seized in the pistons, so your baby will run like ! Frank

Peppermint oil will unseize about anything.

I had F12 that was stuck. Tried everything from pentrating oils, ATF, Fuel oil, etc. Nothing seemed to work. Went through this for about a year. I heard about using rubbing alcahol from the drug store. Cleaned the cylinders out as good as I could and poored enough down the spark plug holes to completely cover the top of the pistons. I let this set for about 3 to 4 hours. I then put tractor in high gear and rocked back and forth with the rear tires. About 4 times of doing this the engine broke loose. Coincedince? Who knows. Made a believer out of me. Make sure to clean alcahol out of cylinders and lube right away to prevent sticking again.

All the sugestions are good except the one too beat on the top of the pistons,,,,they will break. A better way would be to drop the pan and use a bottle jack or floor jack and a pipe or piece of wood going up to a properly positioned crank journal. Just my 2 cents wurth,,,,,Mike

I don't know where you are, but are you sure there isn't ice in the cylinders? I bought a tractor that was 'siezed' in Minn, but when I got home and put the crank to it on a warm day, it turned easily and the water came out of the plug holes....(just lucky, I guess)
I would hesitate to use the grease gun idea (the porta power would probably give you a better control over pressure, and be limited), since the pressures could rupture something in the head (also, make sure the cylinder you are working on is NOT at top or bottom dead center!). I have had luck with the wood block method(making sure you cut one to fit the cylinder hole, as the piston center is thin), and always soaked the rusted cylinders with a penetrant, PB blaster is good, WD40 not as lubrous. Diesel fuel works pretty well. The guy who said to warm up the water jacket with a steam cleaner has a good point, you could also just hook up an engine block heater, and leave it on for several hours. Watch over it, though, as those things aren't always fireproof. If you try turning the crank to loosen it, turn from both ends.

believe it or not, but i have unstuck several engines by pulling the plugs and filling the cyl. up with coke and let set for a day or two, this does work and i have done it, after letting it set, use a wrench on the front pully nut to turn the engine over.

I've had good results with a product called Kroil. It is available from Kano Labs in Tennessee. I used it to free a 2-71 GM and granted, the 2-71 had much more access to the cylinders than you have, but it freed the engine none the less. I also used Kroil on the shifting slides on a D2-3J Cat, that had sat unprotected in the open for at least 20 years. The shifting members were above the oil level and were stuck pretty tight. Lastly, on an Allis HD-5G, which also had sat outside, the gear-locking detent balls had stuck---Kroil was able to free them.
It's about $18-19/gallon plus shipping.
On your IH, you do have the opportunity to insert the liquid through the spark plug holes if the gas/diesel switchover mechanism isn't stuck also.
Good luck.

The grease fitting method will often work good. But the moisture will ussually get into the cylinder that has open valves so start there. A slightly neater way is to use the pump from a porta-power and prefill the cyl. with light oil. Another method that will often help is to drain coolant remove thermostat and put the end of a steam cleaner wand into the water neck. You should be able to get the whole engine to 180-200 degrees and this will help your lubricant penetrate. Most often it takes a combination of methods to achieve success. Good Luck

Hello;
A little known way is to put an adapter on a zerk fitting and screw it into the spark or injector hole. you may need to disable the valves (to make sure they stay closed of course). Then use a grease gun. It is of course very powerful (hydraulic). It provides even distribution of force so not to damage the piston. Make sure you have soaked everything with diesel or kero for lubrication. Hope it helps;
George

Try PB blaster about $4.99 I have had good luck with it, get it at any auto parts store, if that doesn't work pull head and pound on pistons with block of wood, last resort use air chisel with hammer bit !!!!!
