Rototiller Sheave removal

I have a Champion Longlife 3.5hp Rototiller (belt drive system). It appears that the upper bearing to the gearbox is shot. I need to pull the sheaves(pulleys) off the top end before I can drop the gear bos w/tines from the bottom of the frame. There is a bolt with flat washer on top of the sheaves into the drive shaft which I have removed. There is a keyway I can see from the top of the shaft/sheave, but I do not see any set screws.

The question is - How do the sheaves come off the shaft?

I have tried PB Blaster and brute force....

Thanks,

Wayne

If there is no set screw, I'd say it pulls off. Is it a cast iron pulley? If so, you can probably use a puller to get it off. If it's not, you may have to drive it off from the other side with an impact hammer.
