Ordering by number: this is 1280582916 the number that superseded 01158, the American Pneumatic Tool retainer ring. Retaining the tool steel is its whole job. Worn retention lets the shank hammer against the bore and turns a cheap part into an expensive front head.
It shows up in the parts breakdown for the 1133 Rivet Buster and 633 Rivet Buster, and on 2 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
The parts diagram library indexes every breakdown we publish, and the American Pneumatic catalog has the tools these parts go into. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
