Part of the Hitachi Parts Manuals.
Hunting down part numbers again? This 313-page Hitachi EX55UR parts manual PDF (OEM #P1BG-1-2) covers the complete hydraulic excavator, from main frame and counterweight through the piston pump, swing device, travel devices, and full cab group. You get exploded views matched to factory part numbers for every assembly: control valves, pilot pipings, wire harnesses, cylinders, and offset boom components. Each drawing sits beside its numbered parts list, so you match the diagram to the exact reference before you ever call the dealer. Ordering a bucket? This parts catalog separates the 0.11, 0.17, and 0.22 JIS94 buckets, with or without side cutters, plus the 1.7M standard and 2.07M long arms. No more wrong parts sitting on your bench. Bookmarked and text-searchable; type the component name, jump straight to the section, and order right the first time.
