This is the Atlas Copco valve pin part number 3122038200, Crowder SKU AC-3122038200. It directs the flow that reverses the piston in the pusher leg. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
It appears on the ALF 72D 72D-1 Pusher Leg and ALF 67/80 67/80D Pusher Leg breakdown. The tool itself is the Atlas Copco Pusher Leg Attachment For BBC Series Rock Drills. Compare it to the reference callout on the diagram to be sure it is the position you need.
