If you’ve ever ordered a hydraulic pump seal only to find it’s for the wrong serial number range, you know the pain. That’s exactly why a factory parts catalog matters. This Fiat-hitachi EX270-5, EX270LC-5, EX280H-5, EX280LCH-5 Parts Catalog gives you the exact OEM part numbers, not aftermarket translations that leave you guessing. 652 pages of Hitachi’s own breakdowns.

Upperstructure and Undercarriage: What’s Covered

The TOC lists Upperstructure, Undercarriage, Front-End Attachments, River Maintenance Front (18 Type), Breaker & Crusher Parts, ETC., Tools, Name-Plate, Parts Index. Each of these sections is broken down by assembly. For instance, if you need the swing motor mounting bolts, you flip to the Upperstructure chapter. The manual doesn’t lump everything together — it separates by machine configuration (EX270-5 vs EX280H-5, etc.). Page markers like <270> or <280H> tell you exactly which model the part fits. That level of precision is what keeps your parts order from turning into a paperweight.

Service Codes: What Those Letters Mean

Page 5 of the catalog explains each service code: W (field modification needed), H (precision part — don’t disassemble), D (assembly only, no single part), K (part of a service kit), R (shim – quantity varies), S (service-only supply part), Z (engine-related), OP (optional), OS/US (oversize/undersize), # (newly added). If you ignore a “D” code, you’ll order a piece that can’t be bought alone — and you’ll be stuck. That’s why OEM documentation beats any aftermarket reprint.

3 Reasons OEM Catalogs Beat Aftermarket Reprints

1. Hitachi’s own drawings — not redrawn by third parties, so no omitted chamfers or scaled parts. 2. Serial number ranges are exact — the foreword shows applicable serial numbers and region codes ([STD], [USA], [AUS]). 3. Service codes tell you if it’s a special order or oversized part — you won’t waste time ordering a standard part when you need an OS.

Is This Manual Region-Specific?

The foreword mentions STD for standard, USA for North America, AUS for Australia. So if you’re in North America, you need to check for [USA] designation. This catalog includes all regions, so you can filter by your machine’s destination spec. That means the same manual works for a machine shipped to Texas or Tokyo — just pay attention to the codes.

652 Pages of Factory Drawings

The Parts Index at the end organizes everything by part number. Look up a number like A810165 (from the example on page 4) and find the page instantly. That’s faster than any digital search if you have the number in hand. Combined with the exploded views, you can confirm fitment without ever touching the machine.

FAQ

Q: Does this catalog cover the EX280H-5?

A: Yes, all four models are included: EX270-5, EX270LC-5, EX280H-5, EX280LCH-5.

Q: Are torque specs listed in this parts catalog?

A: No, this is a parts catalog. It does not include torque specifications, repair procedures, or diagnostic steps. That information belongs in the separate service manual. However, the parts catalog is essential for ordering the correct seal, gasket, or bearing before you start the job. If you need torque values, refer to the Hitachi shop manual specific to your model. Without the correct part numbers, you risk installing a wrong component that can lead to catastrophic failure. Always cross-reference the service codes (like H, D, K) to avoid ordering parts that are non-serviceable individually.

Q: Can I use this catalog for a machine built after 2000?

A: The serial number range starts at 010001. Check your machine’s serial number against the “Applicable Serial Number” in the foreword. If your machine is newer, some parts may have been superseded — use the “D” date codes to identify changes.

Q: How do I read the service code “K”?

A: K means the part is contained in a service parts kit. Order the kit, not the individual piece.
