Having some issues getting the drive pulley off the straw chopper, so that I can replace the bearing and bearing housing behind it, I sprayed it, torch it, and used a air hammer, still can't get it to move. would anyone have any suggestions on how to get it off, I see there is three hole that got thru the pulley face, didn't know if there was a specific puller that would do the trick. any suggestions would help.

The pulley isn't keyed to the shaft so you may be able to use a couple of large pipe wrenches to break it loose from the shaft. I wouldn't use those three small holes to try and pull from, probably just ruin the pulley by doing so.

we weld a large grade 8  nut on the pulley centered over the hole with a bolt ground to a taper like a puller - weld 360 - this will heat the pulley - then screw the bolt in - instant puller!  leave the nut on - no need to remove - just paint...  this works on bin unloader as well..
