'43 John Deere B flywheel removal

Okay, so I got the flywheel bolts/nuts off and am stumped as how to get the flywheel off. I believe it's rusted on to the crankshaft. My uncle made some oak wedges. Oak was not a match for the flywheel. Any advice? My dad and I prefer to keep our toes from looking like pancakes as well.

You can use a 2 jaw puller or make one using the two 1/2 bolt holes in the flywheel. Penetrating oil and maybe some heat. Good luck

Do what Mark said; plus have help to lift that flywheel, or a cherry-picker, that flywheel is heavy!!!

Check and see if you can find the timing marks between the flywheel and the crankshaft before you pull it off.

B flywheels arent really that heavy,like a D or G. Just be careful.Make a puller using some 2 x 2 with holes drilled to match the bolt
holes in the flywheel. Be sure to mark the flywheel and the crankshaft to get it back in time. There should be a stud screwed into the
crank and a deeper spline in the flywheel to guide you. Be sure the drive lug on the flywheel lines up with the groove in the oil slinger.
Set the end play at .010-.015.

Theres a video on you tube of two fellows taking a flywheel off a 730 if that helps you at all . Maybe you saw it. Just a suggestion
