Valve carries American Pneumatic Tool part number 1280583032, which replaced the older number 18710 and is stocked here under APT18710. It directs the flow that reverses the piston in the scaler. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
Crowder’s breakdowns list this part on the 307 & 317 Needle Scaler. The tool itself is the APT 307 Pneumatic Needle Scaler.
Everything else on that machine is one page away, and the parts diagram library indexes every breakdown we publish. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
