I am still working on getting the motor loosened up. I have the cylinders soaking. However thru the spark plug hole I could see some rust on the valve. I think I am going to have to pull the top off. I have tried just with the hand crank so far and It won't budge. By the way the serial number on this one is tea 209840. Would that be a 1951 or 1952?

I have a to-20 that also is seized, it was running good and I was adjusting the carb and it cut out, when I hit the starter it jammed. I took the started loose and it unlocked, when it hit the starter again it turned slow and would not turn over any more. I tried rocking it and it will not move. I took out the plugs and starter and I can not turn the engine by rocking or putting a screw driver on the fly wheel. Could it be the governor locked ? I am open for any help you good people can give me.
I have had all Fords up til now.
Thanks,
Nick

It is a 1951 Tractor. Have you tried turning the engine the OPPOSITE way like I said in that earlier post on here, remove the Starter and use a small crowbar on the teeth on the Flywheel.Using the starting Handle will be hard to budge it as there is not enough leverage. It could be rusted up and seized or it could be a governor weight come off and jamming the timing chain. If you remove the Head, unless it is the valves that are stuck you wont be any further on with it as it will probably be the pistons stuck in the Cylinders if anything and you can put some diesel into the bores through the plug holes anyway. If you do remove the Head, DO NOT TURN THE ENGINE OVER without clamping the Liners into position or you will damage the liner gaskets and have to remove the pistons and liners to replace them or they will leak into the Oil Pan.If you need more information about all this, just email and tell me what you need...John

If you are unlucky it will be seized, but it should free off if you do as you are doing now, but if a weight flies off the Governor you get the same effect and it can fool you into thinking that the Engine has seized up when what actually has happened is the weight from the Governor has dropped between the chain and the Crankshaft chain-wheel. But turning it with a short bar will have more chance of getting it free than with the Starting Handle, just be aware that when you turn it the wrong way and it seems free that you do try it the normal way too, as it could still be a weight off and it will jam in the chain again while you think it is now free again.
Best of luck with it.....John

It is a 1951 TEA20-85. Keep soaking the pistons and as John (UK) said, remove the starter motor and carefully try turn the engine backwards with the ring gear.

Stuck/rusted valves should not stop the engine turning over but you may run the risk of bending a push rod. I'm not sure on that.

Remove the fuel tank and rocker cover and check the condition of the top end. You may be able to work the valves free.

At the end of the day you may not succeed and may need to pull the engine down, but what you are doing is certainly worth a good try.

Good luck!!!

Thanks for letting me know about the year. I am off today so I am going to have another look and do as you say and take the valve cover off to see what it looks like. I'll keep you posted with how I make out. I was also going to take the starter off and try John's suggestion. My son in law has a backhoe and wanted to give it a push with the hydraulics but I figured it could be too much pressure and my luck something would break. I'll stick to the gentler method for now. Thanks again!
