Lock Spring, American Pneumatic Tool part number 1280583493, which replaced the older number 03161, listed at Crowder Supply as APT3161. Springs in a rivet buster fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It appears on the 133-ST/1133-ST Rivet Buster and 1133 Rivet Buster, and on 6 other machines breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
The parts breakdown index indexes every breakdown we publish, and the American Pneumatic Tool range has the tools these parts go into. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
