In order to paint the brackets that hold the discs to the frame, I need to take apart the discs and take off the sealed bearings. Anyway, the 1 1/2" nut on the end of the disc needs to come off, but I'm having a hard time removing. Do I need a special tool in order to remove the axle nut? There is a permanent "square" that the lock washer and nut butt up against? Do I need a special tool to put on this square in order to counter the pull or removal of the 1 1/2" nut? If need, I have a pic I can post later, but one of these attached pictures may provide a pic of it...

You can expand the nut by making a crease along one flat with a heavy cold chisel, the same direction as the axle. Don't go very deep, about an eighth of an inch or less will free it from the threads enough to turn it. You can still use the nut.

If you don't have the original tool to match the square behind the nut, you can make one out of 1/2 inch steel plate. Cut the square hole to match, weld the plate on a long piece of 1 1/2 inch pipe. Might need to weld the plate on an angle to match the curve of the disc blade. After I lost the short original, I made one, and stick it into the disc frame, latch it with a light chain. It is always with me in the field, should I need it.

The axle is hardened steel & the nut has to be on tight enough to stretch the axle. It is on _very_ tight, & you need to get it back tight.

I sure wouldn't take a good solid disk axle aprt for anything other than to make repairs!

If you must, a very long pipe wrench on the nut with a 4-5' pipe on the wrench, and an equal setup somewhere on the rest of the axle to hold it. A large impact wrench is great, but most of us don't have that large. A torch to heat the nut (NOT the axle or you will ruin it) is sometimes needed.

Retighten it just as tight when you are done.

You've just got to do whatever it takes to hold the axle so it doesn't turn while you remove the nut; depending on make and model, could take a "special" wrench on other end of axle; may can hold one of the spacers with a pipe wrench; may can wedge a piece of wood between blades and frame, etc. Simplest is probably an impact wrench if you've got one large enough. Those nuts have to be TIGHT!!!!! !!
