    Farmall H was running and suddenly quit, crank wont turn

    Oil pan back on, runs great again. Never did find any debris in the cylinders. Thanks again for all of your ideas!

    Farmall H was running and suddenly quit, crank wont turn

    Thanks again for all of your great and helpful ideas. This morning I was able to rotate the crankshaft. I ran a magnet through all the spark plug holes and looked with a bore scope. No abnormalities seen. I blew out each cylinder through the spark plug hole and very little carbon came out...

    Farmall H was running and suddenly quit, crank wont turn

    I put a pry bar against a rod bearing cap and gently nudged the crankshaft. Once it broke free I can rotate the crankshaft 7/8 of a turn back and forth by rotating the rear wheel in fifth gear. When the crankshaft makes a hard stop in either direction, pistons 2 & 3 are nearly top dead...

    Farmall H was running and suddenly quit, crank wont turn

    quote="Blazey"](reply to post at 23:50:18 07/21/19) GOOD NEWS! We are making progress! The crankshaft is no longer "Stuck Hard". I put a block of wood inside the crankcase to pry the #4 rod cap with a small bar and broke the crankshaft loose. I can now turn the crank by pulling on a fan...

    Farmall H was running and suddenly quit, crank wont turn

    MORNING UPDATE: No success yet, but accomplished the following this morning: Removed spark plugs, cylinders dry. Checked oil bath air cleaner, just nice clean oil. No water. Removed magneto. Impulse is intact and free. Removed valve cover. No apparent valve issues. I am...

    I have not tried to pry the flywheel. I am a little concerned about chipping a tooth. It seems if rocking in fifth gear won't budge it something has it locked pretty hard.

    I never got any water near the air cleaner. It's not a fuel, air, carburetor, or starter issue. The crankshaft won't turn.

    Farmall H was running and suddenly quit, crank wont turn

    Thanks for your post! The transmission seems fine. I can shift into any gear and rock it but the flywheel won't budge (I can clearly see the flywheel because I already removed the starter). I feel confident it is not locked in 2 gears because I can shift it into neutral and it rolls fine...

    Farmall H was running and suddenly quit, crank wont turn

    Thanks for your post. I agree that it would be possible to cause the engine to seize if I forgot to refill the oil after changing it but that's not the case here. The day before this happened I drained the oil and refilled with 6 quarts of 30W non-detergent oil. When I ran the tractor for an...

    Farmall H was running and suddenly quit, crank wont turn

    All very good ideas. First off, when I pressure washed it I concentrated on the radiator forward. There had been a mouse nest and considerable grease buildup under the front grill and on the steering box. I did not get any water near the magneto or the breather intake (which I cleaned and...

    Farmall H was running and suddenly quit, crank wont turn

    I will pull the plugs in the morning, but I don't see how it could hydrolock while it was running. Am I missing something? Something caused the engine to quit just as I advanced the throttle after running only a couple of seconds. Then it was locked up.
