Ordering by number: this is R157960, which also shows up as 3310104218, the Chicago Pneumatic throttle valve spring. It is part of the operator control on the chipping hammer. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
Crowder’s breakdowns list this part on the CP 4132 4133 4134 4136 Chipping Hammer and CP 0016 Chipping Hammer, and on 2 other machines. Pull up the diagram and confirm the reference number for your serial before ordering.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
