ABSTRACT:
The pin holes for hammers used in shredders can be changed without the need for removing the hammer pins. A single elliptical hammer pin slot is provided in the hammer. A hammer pin is inserted into one end of the elliptical hammer pin slot and a removable plug is inserted into the slot at the hammer pin thereby securing the pin to the hammer. The pin hole can be changed upon normal wear and tear by removing the plug and sliding the hammer to move the pin to the opposite pin hole at the opposite curved section of the elliptical pin slot. The plug is reinserted at the opposite pin hole thereby securing the pin to the hammer.
