This is American Pneumatic Tool part number 1280582662, which replaced the older number 17948 piston, stocked at Crowder Supply as APT17948. The piston is the striking mass of the breaker; its condition sets impact energy, so scoring, mushrooming, or lost diameter shows up directly as reduced production.
The published breakdown lists it on the 140A Airgo Paving Breaker and 140 Paving Breaker – Former Construction, and on 1 other machine. The tool itself is the APT 140 Pneumatic Paving Breaker.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram hub. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
