Your probably gonna need a puller tool go to a parts store and rent one should come off. But since you said don't ask how did this happen lol?

If its already broken just cut it off or you will need a puller to remove it.

I've run across this. How steady are your hands?

In cases like this, I'll chuck a reinforced cut-off wheel into my Dremel. Then, carefully slit down one side of the pully until you hear a loud *snap* - that would be the internal stresses on the pully hub finally causing it to rupture (it's a tight press-fit, and that will cause it to fail once enough material is removed. Kinda like removing a pressed-on inner bearing race.)

Once one side has split, turn the shaft 180* and slit the other side at least 3/4-way through. Then, insert a flat screwdriver into the first slit and twist - this should force the pully bore open (since you've "relieved" the other side with another cut) and it should fall right off once you tip it up. If it's gotten rusty or nasty under there, you may have to work at it a bit, but it's usually pretty easy.

Paint the shaft with never-seez before you press the new pully on - it will make installation (and later disassembly) easier.

I has pressing it on using the bolt and nut and using a metal bar in the hole of the pulley to keep it from spinning, and it snapped.

Use a proper installer to put the new one on. You won't need to stick anything through the pulley and risk breaking it.

The screw, nut, and washer is the "proper installer" setup - if you use a press, you run the risk of pushing the shaft assembly through the back of the housing.

Just don't stick anything thru the pully - but I've never had to. One wrench to hold the screw, one to turn the nut, and stop when the face of the pully is flush with the face of the shaft.

lol. Don't use a press. An installer like this makes it much easier.

I used a vice when mine went out worked perfect.

I didn't even go that far. 3/8"-16 screw, 3/8"-16 nut, 3/8" flat washers (two, greased between.) Gently clamp the pump in a vice (as a "third hand,") and turn the nut to press the pully on. Easy!
