O-Ring carries Atlas Copco part number 3371814748 and is stocked here under AC-3371814748. 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.
It appears on the LH11 Hydraulic Pick Hammer and LPD-LD Hydraulic Post Driver, and on 10 other machines breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the parts diagram hub; complete tools are on the Atlas Copco lineup. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
