10-20 McCormic flywheel removal

[cooop]

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 are going to need a puller, they sometimes come off easy, sometimes they are areal SOB !

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.

That would be great if you could get a picture! I
didn't realize it was pressed on there.

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.
