Locked up Ford 3600 non-gas

[Baby]

Any clues as what to do to unlock engine after seating out in the winter?

first thing i would do would be to find out why the engine is locked up. is there coolant or some other fluid in one of the cylinders , is there something mechanically locking the engine or are the rings stuck to the cylinder walls. first thing i would do is pull the injectors and see if you can turn the engine by hand using a breaker bar on the crank shaft pulley bolt. if there is no fluid built up in the cylinders and there is nothing mechanically binding up the engine, then i would put a little brake fluid in the cylinders to try and free things up. i surely would not crank it with the starter till you can turn it with a breaker bar on the crank pulley bolt. that is a sure fire way to break something.if you use the brake fluid method, youll need an oil change once you get it running.

Point man thanks for your reply my question is why brake fluid instead of some other type of lub...
Like pb blaster or Wd40.....
PS I think the rings are stuck to the cylinder walls water I think came in through the muffler
Whats your thoughts........thnks

Brake fluid tends to get in small cracks good and does a good job on the rust. A common ingredient is glycol ethers, which happen to be very good organic solvents, this is why brake fluid is sometimes used as a cleaning agent of mechanical parts. I have had good luck with ATF/acetone mix, Marvel Mystery oil, diesel ATF ect

if you have a vertical muffler on your tractor and water is getting into your cylinders, thats bad stuff, especially if your engine sat up most of the winter. reason being, that water will wind up rusting internal parts on your engine, which have very close tolerances, ie piston to cylinder clearances ect. not to mention, if you get pitting in your cylinder walls, you could wind up with broken rings, compression loss ect and have to wind up replacing the sleeves and pistons, and then there is the issue of your combustion chamber filling with water and corroding injector nozzle tips, glow plugs ect. water inside your engine is an all around bad deal. if you are pretty sure its getting in through your exhaust, do what ever you can to keep that water out, cover the exhaust with a bucket, what ever just keep out the water.one question , did you check your engine oil? if so what does it look like? is it grey or milky colored? thats a sure sign of water intrusion. then you just need to narrow down where its coming from. could be the exhaust, especially if you dont have a cover on your exhaust pipe. or it could be coolant from the engine block, which could mean leaking or blown head gasket, crack in the cooling jacket of the block ect. if you are unsure of whether the water came from the exhaust or the cooling jacket, you can pressure test your cooling system with a tester (available at most auto parts stores) or when you get it running, you have an overheat problem. one thing i do, just to kind of keep things easy is start my tractor atleast once a month during the off season and let it run for 15 or 20 minutes. just my 2 cents, hope it helps

by the way, if you use brake fluid to try and free up you engine, keep it off anything with paint that you want to keep paint on. it also works great as a paint stripper.

I personally would use atf/diesel for the rings if stuck. if you found stuck valves.. i'd do the atf / acetone mix.

I don't like playing with brake fluid as much. it loves ( hates ) rubber parts.

Deffinately Do make sure it is not hydro locked, and If water did come in thur a stack. payt he 5$ and get a flap cap! and / or drill a pin hole at the low elbow on the pipe.

I would not try to turn the crank on a stuck engine with a wrench on the crank bolt. Pull the starter and use a lever on the ring gear. It's made for turning the crankshaft. The bolt is made to hold the pulley/damper on.
