Part of the Hitachi Parts Manuals.
Every part on your Hitachi EX25 excavator is mapped somewhere in this 292-page parts catalog PDF (OEM #P1AB-1-4), from the swing post pins to the last O-ring in the pilot valve. You get exploded views matched to factory part numbers for the frame, counterweight, engine, radiator, pump device, swing components, control levers, and the complete cab and canopy hardware. A separate equipment components section strips the gear pump, oil motors, control valves, and the boom, arm, bucket, and blade cylinders down to individual seals, springs, and spools. Picking a bucket? The catalog identifies the 0.035 (300 mm), 0.042 (350 mm), 0.07 (480 mm), and 0.075 (550 mm) options, plus steel and rubber crawler variants. Ordering the wrong pin twice costs you a week of downtime. Bookmarked with a live text layer; type the part name, land on the diagram, order once.
