O-Ring carries Atlas Copco part number 3378512279 and is stocked here under AC-3378512279. Its job is to hold the pressure boundary between two mating faces; a hardened or nicked seal shows up as lost power and a damp housing well before anything else fails.
You will find it on the diagram for the MHC5 Hydraulic Core Drill and LCD 500 & LCD 1500 Hydraulic Core Drill, and on 1 other machine. 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.
Use the parts diagram library to work through the rest of the assembly, or the Atlas Copco catalog 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.
