The Hitachi EX75UR-3 Excavator Parts Catalog (P/N P10V-1-2) covers the listed 2004–2006 model years and machines with serial numbers 010001 and up. It includes parts listings for standard and European Union specifications.

Chapter Bookmarks and Text Search

Navigation and text search: Embedded bookmarks open the main sections and the numerical parts index. Use the index to look up part numbers. The parts lists and illustration labels are unavailable to PDF text search.

The single printable PDF contains 612 pages in English and Japanese. The total includes 596 pages of catalog material, the front and back covers, one machine-record page, and 13 blank pages.

Hydraulics, Undercarriage, and Front Attachments

This selection of catalog contents highlights the main assembly groups. The catalog also lists the tool kit and optional under-mirror parts.

• Upperstructure: The main frame, counterweight, engine mounts, radiator, air cleaner, muffler, and fuel and oil tanks each have parts listings. Separate groups identify the hydraulic pump, swing device, control valve, and their mounting hardware.

• Hydraulic piping: Suction, delivery, return, drain, main, travel, front, lubrication, and pilot lines are broken out by assembly. The relevant layouts distinguish boom, arm, and blade configurations.

• Controls and electrical parts: Listings cover engine controls, travel and blade levers, offset and slide pedals, pilot valves, controllers, monitors, and cab and lighting harnesses. They also identify regional horns and heaters, optional air conditioning, and the offset-boom collision-prevention linkage.

• Undercarriage: Separate groups identify standard and PAT blade track frames, travel devices, front idlers, crawler adjusters, upper and lower rollers, center joints, rubber crawlers, steel track links, pads, and blade piping.

• Front attachments: The offset-boom section covers standard, long, and slide arms. Separate mono-boom drawings and listings identify the applicable buckets, cylinders, links, sensors, guards, and front piping. Breaker and crusher piping and multi-lever equipment have their own groups.

• Parts lookup: Exploded-view callouts match the item numbers in the tables. The tables give Hitachi part numbers, part names, quantities, service codes, serial applicability, and replacement part numbers and quantities.

The catalog suits technicians, parts-counter staff, and owners who can match a machine’s serial number and attachment configuration to an exploded view before ordering.

Matching Serial Numbers and Regional Parts

Regional markings: [STD] identifies standard-specification listings, [EU] identifies European Union listings, and unmarked entries apply to both. The nameplate groups also distinguish offset and mono booms, Japanese and English labels, and HCME and FHE versions for EU machines.

Changes by serial number: The machine serial is the number after the letter P in the product identification number (PIN). Check the range at the top of the assembly list and any narrower range on the individual part row. The catalog uses H for component manufacturing numbers, F for front-attachment manufacturing numbers, and D for dated changes. Those references help you choose between old and new part numbers when the machine serial alone is insufficient.

Replacement Parts and Interchangeability

Service codes: W flags a part that requires work before installation. H identifies a precision part to refer for authorized repair. R means the quantity can vary by machine, as with adjusting shims. D flags a component available only with its assembly, and K marks an item included in a service parts kit.

Replacement codes: I allows the listed replacement to substitute in one direction only. P directs you to use the replacement part. T calls for replacement as an assembly, and Y identifies parts that can substitute for each other. Check the listed replacement quantity before ordering.

Parts Catalog Scope

The hydraulic and electrical illustrations show component placement and routing. For circuit diagrams, troubleshooting, torque settings, fluid capacities, or repair procedures, use the applicable service documentation. For internal engine parts, the foreword directs readers to the separate Nissan BD30 diesel-engine parts catalog.

Use the correct service information and safe lifting, attachment-support, and hydraulic-pressure-isolation practices before physical repair work.

Selected Blade Widths and Arm Lengths

The standard blade has a 2,300 mm parts group for [STD]. The [EU] listings distinguish 2,300 mm and 2,450 mm standard blades from serial 012530 onward, so match the blade width before choosing the parts list.

The standard arm is listed at 1.81 m for the offset boom and 1.62 m for the mono boom. Use the boom type and arm length together to select the matching assembly drawing.
