This is the Atlas Copco packing part number 3100965300, Crowder SKU AC-3100965300. It keeps air or oil where it belongs inside the pusher leg. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
It is called out in the parts diagram for the BBC 34W WS Pusher Leg Drill and BBD 46 WS/WR Rock Drill, and on 4 other machines. 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.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
