This is American Pneumatic Tool part number 1280583434, listed as 00194 before the renumbering front valve chest, stocked at Crowder Supply as APT194. This part controls the working cycle of the digger. When its faces wear, the tool sounds different and the blow rate falls off usually the first thing checked on a slow machine.
It shows up in the parts breakdown for the 119 Trench Digger and 117 Paving Breaker, and on 1 other machine. That machine is the APT 117 Pneumatic Paving Breaker if you are pricing a replacement rather than a repair. 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 full diagram library indexes every breakdown we publish. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
