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

I’ve been turning wrenches for 28 years, and nothing burns my time like ordering the wrong part because some aftermarket drawing had the wrong flange or a mislabeled hose. If you’re working on a Hitachi Sumitomo ZAXIS 110, ZAXIS 110M, or ZAXIS 110-E excavator, you need the factory Parts Catalog – not a third-party guess. This is the same binder the dealer parts counter uses, 638 pages of exploded views and OEM part numbers. No translation errors, no “this might fit” nonsense.

I pulled the oil filter piping on a 110M last week. The manual page layout matched the machine exactly – bracket orientation, banjo bolt thread size, everything. That’s what you get here. The catalog is organized by major machine sections: upperstructure, undercarriage, cab, hydraulic piping, and electrical. Every component is keyed to a parts list with the genuine Hitachi Sumitomo number. You order once, you order right.

Engine and Fuel System Coverage

The ENGINE section breaks down the Isuzu 4BG1T powerplant – mounts, supports, oil filter piping, and all the associated hardware. For fuel, you get FUEL TANK, FUEL TANK SUPPORT, FUEL PIPING, FUEL FEED PUMP, and FUEL DOUBLE FILTER. Each subsystem is a separate exploded diagram. Need the pre-cleaner assembly? It’s there. Muffler? Listed. The catalog even distinguishes between <110,M> and model variants – the side branch piping for the 110 and 110M is different from the 110-E, and it’s clearly marked in the index and on the drawing.

Upperstructure: Frame to Cab

You’ll find the FRAME, BOOM FOOT PIN, CENTER JOINT SUPPORT, COUNTERWEIGHT (including the hanging seat variant), and the entire cab group. The cab section includes STD, EU1/EU2, MEU1/MEU2 spec sheets – with or without OPG guard, vandal hook, sunshade. Power window parts, window washer, radio, even the satellite data communicator brackets are drawn out. The CONTROL UNIT and ELECTRIC PARTS sections (A through E) cover every harness and switch box variant. If you’re chasing a electrical gremlin, the part number for the control unit itself is right there.

Hydraulics and Piping – Factory Layout

Hydraulic plumbing is the worst place to guess. This catalog devotes pages to SUCTION PIPING, DELIVERY PIPING, RETURN PIPING (1) and (2), DRAIN PIPING, and five MAIN PIPING sections. The BOOM BOTTOM PIPING and SIDE BRANCH PIPING are separated by model – <110,M> vs . The PILOT PIPING runs from (A) to (J), covering every branch. Need a seal kit for the control valve? The CONTROL VALVE and CONTROL VALVE SUPPORT pages have the exact part number. The SOLENOID VALVE assembly is shown with all individual coils and spacers.

Who Needs This 638-Page Catalog?

If you own or maintain a ZAXIS 110, 110M, or 110-E, you need this. DIY mechanics who do their own undercarriage work, shop owners who want to stop wasting time at the dealer parts counter, even rental fleets that need to stock the right seals and filters. The catalog also includes the HIGH PERFORMANCE FILTER KIT pages for EU1/EU2/MEU1/MEU2 specs – critical if you’re running a machine in a emissions-regulated region. Beginners can use the exploded views to learn how the machine goes together. Pros use it to order parts before the machine is torn down.

Why OEM Beats Aftermarket Documentation

I’ve seen aftermarket parts catalogs that merge two different model years into one confusing drawing. This one is scanned from the original Hitachi Sumitomo publication, with the original Japanese and English side-by-side on the early pages. The part numbering follows the factory system – you’ll see eight-digit numbers like A810165 for an O-ring. The index at the back lets you cross-reference any part number to the page. No reprints, no third-party re-draws. This is the same file the dealer pulls up when you read them the serial number.

For reference, the Automotive Industry Overview page on Wikipedia explains why OEM specs matter for safety and reliability – same principle here. You wouldn’t trust a knock-off brake line, don’t trust a knock-off parts book.

Frequently Asked Questions

Does this cover the ZAXIS 110M and 110-E as well?

Yes. The catalog includes all three models: ZAXIS 110, 110M, and 110-E. Model-specific parts are marked in the index and on each drawing with <110>, , or tags. EU and MEU regional variants are also listed separately.

Are engine internal parts listed?

No. The catalog says engine internal parts are in a separate Isuzu 4BG1T parts catalog. What you get here are engine support, oil filter piping, radiator, and external boltons.

Can I use this to order replacement hydraulic hoses?

Yes. Each hydraulic piping section shows the hose routing and gives the part number for the complete assembly, including fittings. You’ll need to verify the model suffix (110/M vs E) because the side branch piping differs.

How many pages?

638 pages of scanned OEM content, including the cover, contents, and part number index. No blank fillers.
