Hitachi Sumitomo ZAXIS 230, ZAXIS 230LC, ZAXIS 240H, ZAXIS 240LCH, ZAXIS 240K Parts Catalog

If you’ve ever ordered a hydraulic hose or a counterweight bolt for a Hitachi Sumitomo excavator and ended up with the wrong part because you relied on a generic cross-reference, you know the headache. That wasted time, the machine sitting idle, the return shipping. This is the factory Hitachi Sumitomo ZAXIS 230, ZAXIS 230LC, ZAXIS 240H, ZAXIS 240LCH, ZAXIS 240K Parts Catalog – 694 pages of OEM part numbers, exploded diagrams, and application codes. It’s what the dealer uses. Nothing else gets you the right fastener or seal the first time.

Engine and Cooling System Parts Listings

Under the ENGINE section you’ll find every component from the block to the accessory brackets. The catalog breaks out the oil filter piping, intercooler piping, radiator support, and reserve tank separately. Need the fan belt part number for a ZAXIS 230LC? It’s listed by serial number range. Page 1 of the manual shows that the serial number starts at 010001, so you’ll match your machine’s PIN to the correct parts. The radiator cover and intercooler net are drawn with callouts that include fastener lengths – not something you’ll get from a third-party site.

Counterweight Variations: 5.4T, 6.1T, 6.5T

One of the biggest screw-ups I see is ordering a counterweight for the wrong track configuration. This catalog has three separate entries: COUNTERWEIGHT 5.4T for the <230> models, COUNTERWEIGHT 6.1T for <230,H,250>, and COUNTERWEIGHT 6.5T for . Each one includes the mounting bolts, the shim kit, and the lifting brackets. You get the exact weight and attachment hardware for your ZAXIS 240K or 240H. No guessing if the 6.1T fits – the factory code tells you.

Pilot Piping Diagrams: Why You Need the Exact Hydraulic Routing

Hydraulic lines are easy to misidentify when you’re staring at a cluster of hoses. The catalog dedicates sections to PILOT PIPING (A) through (J), plus separate entries for MAIN PIPING (1) through (4) and BOOM BOTTOM PIPING. Each diagram shows the hose routing and the fittings. If you’re replacing a pilot line on a ZAXIS 240LCH, you pull the model column and get the correct part number for that specific branch. The return piping is split into two sections – (1) and (2) – because the port locations changed across serial breaks. This is the kind of detail aftermarket reprints skip.

CAB Group: From Standard to OPG Guard Seats

The CAB section runs nearly twenty pages and covers every variant: standard cab, HG-type, OPG guard, vandal hook, and even the cab with suspension seat options. You’ll find the SEAT (CLOTH), SEAT (VINYL), and SUSPENSION SEAT (WITH HEATER) for the <250> models. If you need the seat belt for an air-suspension seat, that’s listed separately from the standard seat belt. The window guard, sunshade, and power window parts are all called out with their own part numbers. A lot of owners of the ZAXIS 230 or 240K buy the wrong floor plate because they don’t know the heater-less floor parts are a different assembly. This catalog ends that.

Source Authenticity: Factory Hitachi Sumitomo, Not Aftermarket Reprint

This file is a direct scan of the original Hitachi Sumitomo parts catalog – part number PIHD-I-4. The back matter includes the service code symbols: W for local modification required, H for precision parts only replaceable by the factory, D for assembly-only replacement. Those codes tell you whether you can swap a part individually or must buy the whole unit. No third-party manual I’ve seen includes that level of reference. When you open the PDF, the first page is the English/Japanese title block exactly as it came from Hitachi. For historical context on why factory documentation matters, check the Automotive Industry Overview. The same principle applies to construction equipment – you work off OEM data or you work twice.

7 Critical Sections You Can’t Afford to Miss

The table of contents runs from FRAME through AIR CONDITIONER and every subdivision in between. Engine, fuel system, swing device, control valve, solenoid valve, and electric parts (A through F) are all broken down by model code. The <230>, , , and <250> indicators on each page prevent you from ordering a part meant for the wrong track length. For the ZAXIS 240K you’ll see the HG-type electric parts and the separate console cover. The 694 pages cover everything from the BOOM FOOT PIN to the SATELLITE DATA COMMUNICATOR parts. If you need to order a part for the radio or the fuse box on a <250> model, the catalog has it. Related manuals for later series include the Hitachi Sumitomo ZAXIS850-3 Series Parts Catalog – 451 Pages and the Hitachi Sumitomo ZAXIS 270, ZAXIS 200, ZAXIS 230, ZAXIS 225USR, ZAXIS 225US Work, but for the 230 through 240K family this is the one you want.

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service or repair manual. It lists part numbers, quantities, and exploded views. For torque specs you need the factory shop manual for the same model family.

How do I find the right part for my ZAXIS 240H if the serial number is after 010001?

Look at the top of each page for the model code brackets. For the models (ZAXIS 240H and 240LCH), find the sections marked with . The catalog also includes a compatibility column with symbols: Y means interchangeable, I means that part can replace another but not vice versa, T means interchangeable as a set. The serial number cut-in is noted at the beginning – all machines from serial 010001 onward are covered. If your machine has a later serial, check the “D” (date) indicators in the compatibility column to see when a part was superseded. The 694 pages are organized by assembly groups, so start with the main section (e.g., ENGINE, CAB) then look for the subgroup that matches your machine’s configuration.

Every time I dig into a machine that’s been cobbled together with mismatched parts, I could point to the moment someone ordered from a non-OEM source. Don’t be that guy. The factory catalog gives you the Hitachi Sumitomo part numbers, the exact quantity per machine, and the application codes that tell you whether that counterweight fits your ZAXIS 230 or your ZAXIS 240K. You can spend four hours on the phone with a dealer parts counter, or you can download the factory manual and have the answer in thirty seconds. Hitachi Sumitomo ZAXIS 230-240 Parts Catalog 694 Pages OEM is right here. Automotive Industry Overview also confirms that OEM documentation is the standard for correct identification.
