This is Chicago Pneumatic part number 3377000785 rear plate, stocked at Crowder Supply as CP-3377000785. It forms part of the machine’s structure, carrying load and keeping dirt out of the working parts.
You will find it on the diagram for the LP 18-2×20/1×40 Twin PE Hydraulic Power Pac and PAC P18 Twin E11 Twin Hydraulic Power Pac. That machine is the Atlas Copco LP 18 Twin Hydraulic Power Pack if you are pricing a replacement rather than a repair. 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 full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
