This is American Pneumatic Tool part number 1280583797, which replaced the older number 02598 steel retainer, stocked at Crowder Supply as APT2598. This part keeps the steel captive in the rock drill under repeated impact, so it is inspected at every steel change and replaced on condition rather than on a schedule.
Crowder’s breakdowns list this part on the 137 Rock Drill. The complete machine is the APT 137 Pneumatic Rock Drill.
Everything else on that machine is one page away, and the full diagram library indexes every breakdown we publish. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
