Retainer Ring is the Atlas Copco service part carried under part number 9232120290. This part keeps the steel captive in the breaker under repeated impact, so it is inspected at every steel change and replaced on condition rather than on a schedule.
It shows up in the parts breakdown for the Red Hawk Gas Breaker/Drill and Cobra Combi Gas Breaker/Drilll- before 2010, and on 1 other machine. 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 full diagram library to work through the rest of the assembly, or the Atlas Copco catalog if you are pricing a replacement machine. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
