Piston is the American Pneumatic Tool service part carried under part number 1280583496, which replaced the older number 03165. It is the working heart of the rivet buster. Pistons are matched to the cylinder bore, so replacing a worn one usually means checking the bore at the same time.
You will find it on the diagram for the 133 Rivet Buster and 133-T/1133-T Rivet Buster, and on 2 other machines. 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. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
