1939 Farmall F 20 Flywheel Removal

Casejohndeergirl · Sep 20, 2017

My fiancee is trying to remove a flywheel from,his 1939 Farmall f 20. He has tried making a puller but it wasn't heavy enough and it broke. What are some other methods he could use to remove the flywheel?

two piece of angle iron across bell housing with holes drilled to match treaded holes in flywheel I think it is 5/8" treaded rod you need with nuts. this will pull it off. To put it back on google Nebraska Kirk flywheel installer.

I have had success using a large gear puller in the holes and a metal plate on the end of the crank shaft.
The round "Key" is not threaded and should slide out with the flywheel.

Do as others have suggested. I have seen flywheel pullers made from thick steel plate, and a several ton bottle jack. These flywheels are stubborn on the Regular and F20 series. I gave up on mine after trying a puller that was lended to me, AND using a abundant amount of PB Blaster with an Oxy-Acetylene torch. Wouldn't budge.

If you google Farmall F20 Flywheel Puller, you will see many versions people have used in the images section. It is a project to get it done, and then pressing it back on is another project in itself.

Let us know how you handle it, and good luck.
