Hydraulic schematics and wiring diagrams back up the listings for the upper hydraulic lines and the cab and engine harnesses, while a closing parts index cross-references part numbers. Check relief settings as printed: 37.8 MPa at 30 L/min for the F1 port relief valve, 24.5 MPa at 220 L/min for F7. Whether your job is rebuilding the idler adjust assembly or adding boom safety hose lines, the part numbers are grouped by assembly. Bookmarked and searchable, it travels wherever your excavator works.
