I have a H that has been sitting idle for 4 - 5 years inside. What is the best way to loosen up a stuck engine? Any miracle solvents that anyone can recommend?

I have had real good luck with penetrating oil in the spark plug holes for a few days . Then fill the water jacket with boiling water. Rock it back and forth. But every time the rings knocked out of the pistons. Good Luck

When I tore down my first B three and four were rusted in place. The tractor had been sitting out in the rain, which poured into the cylinders through the head and froze things really nice.
I tried everything.
WD 40, brake fluid, transmission fluid, burnt oil, some funky stuff from Wal-Mart, then it was PB Blaster, pounding the fool out of it with a hammer and a piece of wood...jacking up the tractor with a block underneath the rods... nothing moved.
Then my brother-in-law found my this little product called, S'ok.
The next day, my grandfather introduced me to this little tool called a brass hammer.
Three days of S'oking later and about a dozen really good knocks on the rods, the pistons were out.
I'd find my a case of S'ok at an industrial supply house, pour half a bottle into each cylinder.
Just my two cents.

My H set for over 20 years outside, put diesel in the cylinders and jacked up one of the back wheels. Put it in third gear and rocked the tire back and fourth for probably two months, adding diesel quite often. It finally moved. Then used a tire tool through the starter hole on the flywheel to push out diesel on cylinders that held it. It's a running but I may of broke a ring on #2 cyl., not for sure yet...

I have had great luck with taking out the starter and using a prybar on the flywheel. This is the easyest point to turn the engine, just be careful not to chip a tooth on the flywheel

Here is what hasn't worked yet. Purchased and A-I at a consignment sale. Looked bad but was all there. Got it home and found that the engine and raditor were full of anti freeze, a good sign. Pulled the head and pan, found no rust or water where it shouldn't be, another good sign. filled cylinders with PB Blaster and let it sit two days. Unbolted the starter to make sure it wasn't part of the problem. Got out the 5lb hammer and block of wood, beat the block of wood into splinters and wore out my arm. Got out the Act. torch and heated the cylinders up as hot as I was comfortable with, soaked in PB Blaster again for a day. New wood block and hammer, no luck. Purchased some Kroil, soaked again for two days, still no luck. Number 1 & 4 pistons are down and numbers 2 & 3 are up. Oils will leak past over night in 1 & 4 but not in 2 & 3. Reassembled looslly and pickeled it with Kroil. Put a 75lb weight on the end of the crank, three weeks later, still no luck. Tryed a cheater on the crank, bent crank. Check every week and fill with Kroil where needed, still waiting 2 months later. GOOD LUCK WITH YOUR PROJECT.

Bill After you have let whatever you put in the engine soak for a couple days. Use a big pipe wrench on the front of crank & try to turn one way & then the other.Thats how I got a M freed up. Good luck Will

Whether it will work or not I don't know but an old Cat mechanic told me the other day that they always used peroxide. I'm working on un snsticking an Allis C but I have already filled cylinders with B G Force but no luck yet. Nearly every engine I've worked on that was stuck I've had to use sledge hammer and block of wood. Of coarce here in Texas things rust pretty bad. LOL

PB Blaster is about the best stuff I have ever used. You can get it at most automotive stores. Spray the cylinders real good and let it sit for a day. Good luck- Roy (MD)

I agree with PBlaster, I will also recomend letting it sit for a few days. Luck.

Bill, I know everyone recommends penetrating oil but I read in an old car mag. that most engines are stuck from gummed fuel in cylinders especially if they were covered or kept inside. They said to use a mixture of acetone and fuel oil, take out plugs and fill cylinders with mixture then fill radiator with HOT water. This will expand the cylinders slightly and the pistons will not expand because of the air gap allowing the mixture to dissolve the varnish. Might take a few attempts but the guy who wrote the article said it worked on 23 out of 25 engines. Might be worth a try. He didn't say what ratio the mixture should be. LOL Gene

If you can take the pan off, you can look up the cylinder. You will probably see rust below the piston. The chances of having it move over all that junk is slim. What I had to do is disconnect the connecting rod and push (beet with mallet and wood stick) the piston out the top. You might have to ream the ridge first. After the piston is out, then hone out all the rust and reinstall the piston.

Good Luck.
