Ordering by number: this is 3121016701, the Atlas Copco valve casing. This part controls the working cycle of the pusher leg. When its faces wear, the tool sounds different and the blow rate falls off usually the first thing checked on a slow machine.
The published breakdown lists it on the BBC 16W WS Pusher Leg Drill. That machine is the Atlas Copco BBC 16W Pneumatic Rock Drill if you are pricing a replacement rather than a repair. 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. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
