Hitachi Construction Machinery ZX140W-3 Parts Catalog

If you’ve ever ordered a part for a Hitachi wheeled excavator and got the wrong oil filter bracket or a fuel line that doesn’t match the mounting holes, you know the frustration. That wasted trip to the dealer, the machine sitting idle, the job delayed. A parts catalog that tells you the exact part number for your specific serial number range and regional spec is what keeps that from happening. This Hitachi Construction Machinery ZX140W-3 Parts Catalog is the factory-issued document that mechanics and parts managers rely on – 597 pages of part numbers, exploded diagrams, and compatibility codes that leave zero room for guesswork.

597 Pages of Part Breakdowns

You get every major system laid out: Engine assembly with its Isuzu AI-4JJ1XYSA-02 block, Fuel tank and fuel feed pump, pump device with supports, swing device, control valve, pilot piping from A to K, brake piping, steering piping, electrical parts broken into A through F, air conditioner with heater piping, cab variants for Japan, Europe, and North America, and the undercarriage section. Each section has its own page number in the bookmark, so you flip directly to the exploded view and parts list. The Fuel Tank support and fuel piping chapters are separate – no hunting through generic plumbing diagrams. You land on the exact line item.

Engine Assembly: Isuzu AI-4JJ1XYSA-02

The engine is listed with its full model number on page 2 of the catalog: Engine Type AI-4JJ1XYSA-02. That’s a 4-cylinder diesel built by Isuzu. The catalog includes engine support, oil filter piping, intercooler piping, and all attaching parts. If you need the radiator, radiator support, or the reserve tank, those are listed as separate groups. The Internal Combustion Engine section alone covers everything from the pre-cleaner to the muffler. Don’t rely on a generic engine parts listing – this catalog gives you the Hitachi-specific brackets and fasteners.

Region-Specific Parts Listings: [EU], [NA], [JPN]

One of the most useful features is the region codes printed on each page. For example, the control lever sections have variants for [STD], [EU], and [NA]. The cab parts list different glass options: laminated glass for EU, vandal cover seat for NA. The radio sections are split between Japan, North America, and EU/Asia/Oceania. If you’re working on a machine imported from Europe, you need the [EU] part numbers. This catalog marks them clearly. No more ordering a JPN console cover for an NA machine and finding the bolt holes don’t line up.

Compatibility Symbols Explained

Hitachi uses a symbol system on every parts page: Y for unconditional interchangeability, I for one-way substitution (you can use a newer part but not the old one), P for prohibited part with substitution listed, D for parts that must be replaced as an assembly, K for items included in a service kit, R for parts where quantity varies per machine (shims, etc.), and OP for optional equipment. These symbols run down a column next to each part number. If you see a P, the part is obsolete – the alternative part number is given right there. This alone saves hours of cross-referencing on dealer websites.

The Fuel Feed Pump section, for instance, lists the pump device and its support separately. The Fuel Piping chapter includes every hard line and hose from the tank to the injection pump. With 597 pages, you’re covered from the boom foot pin down to the floor mat. Even the spare pedal less parts and the rain-visor under the front head lamps are in there.

OEM Documentation vs Aftermarket Reprints

This is a direct scan of the original Hitachi factory catalog, not a third-party compilation. Aftermarket parts catalogs often merge several models into one book, leaving out serial number breaks and regional notes. Here you get the exact PDF that Hitachi dealers use – serial number 002001 and up. The memorandum page at the front lists the engine type and asks you to fill in the product identification number and engine manufacturing number. That’s the level of detail the factory expects. For a truck shop or a home garage that services wheeled excavators, this is the only source you should trust for ordering parts.

Does this parts catalog include engine internal parts like pistons and rings?

No. The foreword on page 3 states: “For the engine parts, please refer to the parts catalog of diesel engine issued separately.” This catalog covers the mounting, piping, and accessories attached to the engine (alternator, turbo piping, etc.), but not engine internals. You need the Isuzu engine parts catalog for those.

How do I look up a part if I only have the old part number?

Use the compatibility symbols. If the old number appears in a parts list and has a I or P symbol, the alternative part number is printed in the replacement column. For supersessions not shown, you can search the PDF for the old number – the bookmarks are grouped by chapter, but the text is searchable in most PDF readers. Also check the serial number range on each page; Hitachi often changes part numbers at a specific machine serial break (shown as D for date or H for machine serial).
