This is the Atlas Copco lever part number 3115119100, Crowder SKU AC-3115119100. This is control gear it meters air to the rock drill. A worn control gives creep, hard starting, or a tool that will not shut off cleanly.
It is called out in the parts diagram for the RH 572E Rock Drill and RH 571-5L 571-5LS Rock Drill. That machine is the Atlas Copco RH 572E Pneumatic Rock Drill if you are pricing a replacement rather than a repair. 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.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram library. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
