Seal is the Atlas Copco service part carried under part number 3115210500. It seals a pressure joint inside the pusher leg, and because elastomer takes a set long before the metal around it wears, it is one of the first items to replace when a machine starts weeping air or oil.
Crowder’s breakdowns list this part on the ALF 71 71-1 Pusher Leg and ALF 72D 72D-1 Pusher Leg. That machine is the Atlas Copco Pusher Leg Attachment For BBC Series Rock Drills 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.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts breakdown index. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
