I have removed the 2 retaining screws and tried prying gently but will not come off? Don't want to ruin. Any tips?

It should just slip off, keep working it. The only thing holding it stuck would be the cast iron fingers on the inside of the hub, and that is a slip over it. You may be able to "spin" it to break that bond. A tiny bit of oil at those fingers may help, but try to drop it on, not spray it. It's best not to coat it in oil.

PS, the 20 amp one is not the same size and needs a different flywheel from what I understand in case you are going there.

Here is a photo, you can see the three fingers around the inside of the alternator that I speak of. (Anyone ever wonder if I really do have a photo of EVERY part of a Massey Ferguson at my finger tips?) LOL

I took mine off the other day by placing a screw driver in between the three fingers on the inside and prying out just a little and rotateing around untile it came off and mine was very rusty.

Hopefully the wd40 will help loosen it up for you.

I would try very carefully to get it to rotate to break the bond. I'd carefully use a screwdriver in one of the screw holes and tap it with a hammer to make the coil assembly rotate. Penetrating oil can work magic on things like this. Hopefully it will pop right off tomorrow.

If when you rebuilt you took photos of every step. you should end up with it all photographed. that is what I plan on doing.
