This is Atlas Copco part number 3115248600 upper part silencer, stocked at Crowder Supply as AC-3115248600. Exhaust treatment on a rock drill is a hearing-protection item as much as a comfort one, and elements load up with oil and dust over time.
It appears on the RH 658L/LS/LS-01 Rock Drill breakdown. That machine is the RH 658 L Surface Rock Drill if you are pricing a replacement rather than a repair. 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.
