Ordering by number: this is C113780, which also shows up as 3310103475, the Chicago Pneumatic spring retainer. Retaining the tool steel is its whole job. Worn retention lets the shank hammer against the bore and turns a cheap part into an expensive front head.
It appears on the CP 0010 Centrifugal Pump breakdown.
Everything else on that machine is one page away on the parts diagram library; complete tools are on the Chicago Pneumatic lineup. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
