Ordering by number: this is 3377021501, the Atlas Copco spool. It directs the flow that reverses the piston in the power pack. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
The published breakdown lists it on the PAC P9 Hydraulic Power Pac and PAC P13 Hydraulic Power Pac, and on 1 other machine. 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.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
