Back Head Ass’y – Dry, American Pneumatic Tool part number 1280583481, which replaced the older number 02349, listed at Crowder Supply as APT2349. The back head closes the top of the rock drill and carries the air inlet and control gear, so damage here usually shows up as a leak at the handle rather than lost power.
It is called out in the parts diagram for the 137 Rock Drill. That machine is the APT 137 Pneumatic Rock Drill if you are pricing a replacement rather than a repair. Compare it to the reference callout on the diagram to be sure it is the position you need.
