Are there any tricks to removing the flywheel on a 10-20? I have the big nut removed. It just doesn't want to come off. Suggestions? Thanks
 
You MUST have a puller as the flywheel is pressed onto the end of the crankshaft. I made a puller that uses an 8 ton hydraulic jack to pull it off. Getting them to start moving sometimes takes all that 8 ton jack has! I will have to get a picture of it for you to see.
 
Please do get your puller pictures posted. I'm
having the same problem with a F20. I have some
ideas, but would like to see yours.
 
I found this one picture in my files. This was taken when I was rebuilding my Farmall Regular. I have since used the puller on F20, F30, 10-20 and 22-36 flywheels, it removed them all.

A different tool is needed to press the flywheel back on the crankshaft, I have not yet made one to do that.
