Part of the Hitachi Parts Manuals.
All 236 pages of this Hitachi EX40UR parts catalog PDF (OEM #P1BA-1-2) focus on one thing: getting the exact replacement components for your excavator. Inside, you get highly detailed exploded views of the entire machine, from the swing device to the offset boom assembly. Open to the hydraulic sections to find complete breakdowns of the control valves, travel motors, and pilot pipings, complete with factory numbers for every individual piece. Match the exact O-ring for the main relief valve, and verify the correct replacement shoe, retainer, and block assembly before rebuilding your piston pump. Stop ordering the wrong components from vague aftermarket schematics. Bookmarked and searchable; jump to any section or search any component by keyword so you can get back to work.
