Here is a poor pix of the PTO end of the crank.

Use a split bearing separator behind the gears and pull on it. Hal

The gears are put on HOT, and then when they cool they lock into position. A good puller usually can pull them off, but you may have to heat them with a torch if they are stubborn. don"t heat the shaft, just the gears.

Depending on its age, it might be a 2 piece gear, or a single gear. I"d use a bearing puller or something behind the gears so your puller jaws aren"t pulling on the gear teeth (they break).

IF you go here, you will find gravely manuals that will show you how to do all this stuff.

What engine? The best thing to do is find a diagram of the engine.

Maybe wait for a reply from someone that does know what the engine looks like inside before trying anything below.

I think you are right. Those do look pressed on. There might be a C clip inside the engine. Those gears might be a seperate shaft from the crankshaft similar to a camshaft.

I am not sure what that engine looks like inside. I would pull the 4 bolts on that plate and see what is on the other side. Don't be too rough with it, I don't want you to break anything expensive!
