Shaft Seal is the Atlas Copco service part carried under part number 3376100719. It seals a pressure joint inside the 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.
It appears on the MHC5 Hydraulic Core Drill and LCD 500 & LCD 1500 Hydraulic Core Drill, and on 1 other machine breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
Use the full diagram library to work through the rest of the assembly, or the Atlas Copco tool range if you are pricing a replacement machine. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
