Washer is the Atlas Copco service part carried under part number 3115057400. It spreads clamp load and protects the face under the fastener routine hardware, but the wrong one changes how the joint holds torque.
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.
Work through the rest of the assembly on the same breakdown, or start over from the parts breakdown index. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
