Ordering by number: this is Y10212190, the Tamco/Toku valve knock pin. This part controls the working cycle of the chipping hammer. When its faces wear, the tool sounds different and the blow rate falls off usually the first thing checked on a slow machine.
It shows up in the parts breakdown for the THH 1 2 3 4 Chipping Hammer. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the full diagram library; complete tools are on the Tamco/Toku tool range. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
