Hitachi Sumitomo ZAXIS 110, ZAXIS 110M, ZAXIS 110-E Parts Catalog

If you are turning wrenches on a Hitachi Sumitomo ZAXIS 110, 110M, or 110-E excavator, you already know the pain of ordering the wrong part because the aftermarket listing said “fits all models.” That mistake costs you a week of downtime and a restocking fee. This is the Parts Catalog – 638 pages of factory-issued exploded diagrams, part numbers, and application tags. Not a reprint from some third-party that skips the <110,M> vs <E> differences. The book is split into major groups: Upperstructure, Engine, Fuel system, Swing device, Controls, Cab, and Electric parts. Each section uses tags like [EU1], [STD], or <110> to tell you exactly which machine and region the part belongs to. If you have ever had a fuel feed pump that looked right but didn’t bolt up, you understand why these tags matter.

Engine and Fuel System Coverage

The Engine section (page references are in the bookmarks) covers the mounting, oil filter piping, radiator, air cleaner, pre-cleaner, muffler, and all support brackets. The Fuel section includes the tank, support, piping, feed pump, and the double filter. Each component is drawn with a callout number and the corresponding part number listed in the table. No guesswork about which O-ring or banjo bolt fits the 110-E versus the 110M. The document also notes that engine internal parts are in a separate Isuzu 4BG1T catalog – so don’t go hunting for piston rings here. What you get is the machine-side hardware: mounts, clamps, hoses, and the exact fuel line routing.

7 Systems Broken Down by Machine Variant

Upperstructure, Swing device, Travel controls, Pilot piping (10 sub-sections from A to J), Auto/manual engine control, Electric parts (A through E), and Cab assembly. The Pilot piping section is split by model variant: <110,M> and <E>. If you are retrofitting a 110M control pattern onto a 110-E, you need those separate diagrams. The Electric parts section has separate sub-sections for auto engine control versus manual engine control, and further splits for <110, M> vs <E>. That level of detail keeps you from ordering a wiring harness that ends three inches short.

What Torque Values Are Listed?

This is a parts catalog, not a service manual. Torque values are not printed on every page. But the exploded views show fastener locations and part numbers – you can cross-reference those against the factory service manual if you have it. The real value here is identifying which bolt, seal, or hose assembly the dealer part number actually matches. For example, the Boom foot pin section lists the pin and bushing part numbers for the upperstructure frame. Without this catalog, you might order the pin for a ZAXIS 110M and find it doesn’t fit the 110-E. The catalog’s index at the back lists every part number in numeric order, so you can check a number before you buy.

Audience Fit – Who Needs This 638-Page Document?

Three groups. First, a shop owner who keeps a fleet of these excavators and needs to stock common wear parts like oil filters, air cleaner elements, and fuel filters. Second, an independent mechanic who takes on a ZAXIS 110 that has been patched with mismatched parts – you need the correct diagram to sort out what was changed. Third, an owner-operator who wants to order parts directly and avoid dealer markup. The document is written in both English and Japanese (the foreword is bilingual), with part numbers in alphanumeric format. You don’t need to speak Japanese to read the diagrams – the numbers and references are universal.

Source Authenticity – OEM vs Aftermarket Documentation

This is the original Hitachi Sumitomo factory file, file name HITACHI_ZAXIS_110-ZAXIS_110M-ZAXIS_110-E_Parts_Catalog_en-ja-31114003920.pdf. It was produced by the manufacturer for dealers and service centers. The aftermarket parts catalogs you find on sketchy forums often reorder the pages or leave out the model-specific tags. Here, the foreword explicitly explains the tagging system: <110> for Zaxis110, <M> for Zaxis110M, <E> for Zaxis110-E, [EU1] and [EU2] for European variants, [STD] for standard regions. No guessing. The document also includes a memorandum page for writing in your machine’s serial number and engine type. That is a dealer-level detail.

FAQ

Does this catalog include wiring diagrams?

No. It shows electric parts (battery, fuse box, head lamps, control unit) in exploded view with part numbers, but it does not contain wire routing or circuit schematics. You need the electric service manual for that.

How do I find a part number for a 110M boom bottom piping seal?

Go to the “BOOM BOTTOM PIPING” section. Look for the seal callout. If the part is only used on the 110M, it will have <M> after the name. The part number is listed in the table next to the callout. Cross-check with the serial number range printed on the upperstructure frame plate (product identification number).
