Part of the Hitachi Parts Manuals.
This 234-page Hitachi EX30UR-3 parts catalog PDF (OEM #P1BR-1-1) maps every component on your EX30UR-3 hydraulic excavator, from the piston pump to the offset boom pins. You get exploded views with factory part numbers across the whole machine: engine, radiator, pump device, swing device, pilot and solenoid valves, plus full undercarriage coverage of front idlers, rollers, track links, and both rubber and steel crawler adjusters. A separate equipment components section strips the oil motors and every cylinder down to individual pistons, bushings, seals, and packings. Need proof it's the real factory book? It breaks out the Track-Link 300G assembly and the 0.08 cubic meter JIS94 bucket (450 mm wide) piece by piece. One wrong part number costs you a week of freight. Bookmarked and searchable; find the diagram, read the number, order it right the first time.
