This is American Pneumatic Tool part number 1280583756, which replaced the older number 02375 ratchet ring, stocked at Crowder Supply as APT2375. It drives or indexes rotation. When it wears, the tool still hammers but stops turning the steel evenly.
It shows up in the parts breakdown for the 137 Rock Drill. It comes off the APT 137 Pneumatic Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts breakdown index. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
