Compression Spring carries Chicago Pneumatic part number C113779 (also carried as 3310103957) and is stocked here under CP-C113779. Springs in a pump fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It shows up in the parts breakdown for the CP 0010 Centrifugal Pump. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram hub. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
