This is the Atlas Copco damper part number 3115231000, Crowder SKU AC-3115231000. It takes the recoil load so the surrounding parts do not. Compression set is the usual reason to change one.
It appears on the ALF 71 71-1 Pusher Leg and ALF 72D 72D-1 Pusher Leg breakdown. That machine is the Atlas Copco Pusher Leg Attachment For BBC Series Rock Drills if you are pricing a replacement rather than a repair. Check it against the reference number on the diagram first; serial breaks change what fits.
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.
