Valve Housing is the Atlas Copco service part carried under part number 3371817115. It directs the flow that reverses the piston in the rock drill. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
Crowder’s breakdowns list this part on the LHD 23M Hydraulic Rock Drill and RDR 48R Rock Drill, and on 1 other machine. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
