Whats the best way to get an old tractorunstuck

Walt355 · Apr 1, 2010

Ive got a cub that was locked when I bought it, Assuming from sitting. I poured a concoction of diesel, tranny fluid, adn PB blaster down the holes, let it sit a few days and nothing, So I sprayed it down good and left it sitting in the barn, This was 2 years ago. Messed with it for a while While ago and its still stuck tight. What kind of a trick does everyone else use?
Thanks

If you soaked it that long and it hasn't moved, you're looking at a rebuild in my opinion.

I did the same with an Oliver 60 a couple years ago, after several months that engine wouldn't budge one iota. Wrote that one off.

If it has sat that long and it still is not free then you will most likely have to rebuild it. But you can try one more thing first but maybe a 25% chance it will work. Pull the head off and then take a piece of oak 2X4 and cut it down to fit the cylinders. Drop it in each cylinder and whack it a good lick with a hammer. Then try to spin it over with the starter and a 12 volt battery use fast short taps on the starter switch

Walt:

You ask for the "best way." The best way is usually disassembly. There are several easier ways that are sometimes successful, but usually these are not the "best way."

P.S. Oftentimes, "stuck" engines, especially flatheads, are siezed due to the valves siezing in the guides and/or the lifters siezing in the lifter bores. I would remove the tappet cover and inspect. I would also remove the cylinder head to inspect.

I can't believe it!!!!!! old commented on a stuck tractor and for the first time ever did not mention ATF. What is the world coming too?

I have worked on several Cubs. I am willing to bet that you will have to take it apart. Stuck pistons would be the least of my worries. The valves are what you need to look at. They don't have replaceable seats and may be pitted from water getting in there. Once you get the head off you could see that the valves are stuck and or will not close after you get the motor to turn over.
I take the starter out and use a small pry bar to work the motor back and forth. Good Luck - Jim

Remove the head. usally only one piston is stuck. install a steel disc one half inch thick. bolt on a t-bar on top of the block and turn the screw until the piston breaks loose.works every time.

I read today,use hydrogen-peroxide.it penetrates and bubbles out the rust.But you gotta use it BEFORE oil,or it wont work......try it.
