Spring is the Atlas Copco service part carried under part number 3131001600. Springs in a rock drill fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
You will find it on the diagram for the BBD 46 WS/WR Rock Drill. 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.
Everything else on that machine is one page away on the full diagram library; 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.
