This is the American Pneumatic Tool throttle valve part number 1280583378, which replaced the older number 18051, Crowder SKU APT18051. This is control gear it meters air to the breaker. A worn control gives creep, hard starting, or a tool that will not shut off cleanly.
You will find it on the diagram for the 140 Paving Breaker. The tool itself is the APT 140 Pneumatic Paving Breaker. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away, and the parts diagram hub indexes every breakdown we publish. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
