Seal Ring is the Atlas Copco service part carried under part number 0661100040 (also carried as 3377016375). It seals a pressure joint inside the rock drill, 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 LHD 23M Hydraulic Rock Drill and PPU22 Hydraulic Post Puller, and on 7 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.
