Spring is the Chicago Pneumatic service part carried under part number H3438840 (also carried as 3310104863). Springs in a chipping hammer 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.
Crowder’s breakdowns list this part on the CP 0017 SVR Chipping Hammer. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
Use the parts diagram library to work through the rest of the assembly, or the Chicago Pneumatic lineup if you are pricing a replacement machine. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
