HELLO
NEED INFO ON HOW TO FREE UP A STUCK 7060 ENGINE.
HERE IS A LITTLE BACK GROUND. THIS TRACTOR WAS RUNNING 10 YEARS AGO, IT STARTED RUNNING HOT SO THE GUY PARKED IT. IT HAS BEEN PARKED EVER SINCE. I CHECKED THE OIL, NO WATER IN THE BASE,AND THE OIL HAS NO BURNT SMELL TO IT.
MY BIGGEST CONCERN IS IF I GET IT TO TURN OVER, AND THERE IS ANY RUST (LIGHT SURFACE) ACCUMULATED ON THE SLEEVES, WOULD IT DO DAMAGE TO THE RINGS. IF I GET OIL IN THE BORE WOULD THAT HELP? OR SHOULD I JUST PULL THE HEAD AND CLEAN THE SLEEVES AND LIGHTLY TAP ON THE PISTONS WITH A BLOCK OF WOOD WHILE TRYING TO TURN THE ENGINE OVER. THANKS FOR ANY HELP

More than likely when shutdown an exhaust valve was open, and water got in through the muffler, the drain hole in the turbo elbow plugs easily. If that is the case figure on a tear down. I hate to say it, but there is now other real way to know for sure, I would hate for you to get her running with crud in one hole, only to break something or push something out the side. If you had a small borescope you might be able to do some more investigation. Start by pulling the rocker arms and see if all the valves come fully closed, if they do, then pull the exhaust manifold, see what the ports look like, this will give you a lot more information without getting too deep into the project.

Pull the head and find out what is going on in their, if you are going to try and fix it any way

I picked up a WD that was stuck and got it free by putting ATF and acetone mixed up into the cylinders. took a couple weeks of letting it drain past the rings to free it up. I did pull the head off to see how bad it was and there was little to no rust anywhere, so just the rings were a little seized up from sitting. If it were me, for the cost of a head gasket, I would take the time and pull the head and see what you find. Will give you insight into how bad it is and how wore everything is by the ridge in the sleeves. You may open a can of worms, or you may be suprised. Every time I get a stuck engine, I take the head off and look inside. It's so easy to do and doesn't take much time to get it apart, and then you know what you're in for.

If it started running hot, there is a possibility of something else wrong with the engine.
If there is rust in the cylinders it would more likely score the cylinders and the piston. The rings would be the smallest of the concern. They are expendable items.

Check the radiator to see if its clean. That might tell you why i ran hot. Bought a 8070 last year that had been running hot and when they took off the head they found one sleeve bad and when they took engine apart found one piston was missing rings and part of the piston was gone, all because the radiator was pluged. It looked like someone had washed it with a garden hose for years! Rings had got so hot that you could bend them around backwards!

I have taken the chance with breaking loose smaller motors without taking off the head before and gotten lucky more than I have gotten hurt. Something as big as a 7060 I agree that you should pull the head and see what you've got. I bought a stuck 7060 this summer and was able to get it to turn backward with a crowbar to the flywheel, but it wouldnt go all the way around. When I took the head off, I couldnt believe what I saw. 5 cylinders looked brand new (but several of those pistons had stuck rings when I took them down to inspect) but one cylinder was absolutely junk. It looked like it had been lying in the fertilizer pile of the salt plant. When I replaced it with a good usable extra I had, it turned into a really good tractor, but I would have ruined a lot if I hadnt pulled the head. Good luck!
