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

Ever ordered a part for a Hitachi Sumitomo excavator and got the wrong piece because you guessed the serial number break? That kind of time-waster ends the second you open this 694-page parts catalog. I’ve seen guys pull a fuel filter for a ZAXIS 230 and end up with one that fits a ZAXIS 240LCK because they didn’t have the right illustration. This book kills that guesswork cold.

The document covers five core models: ZAXIS 230, ZAXIS 230LC, ZAXIS 240H, ZAXIS 240LCH, and ZAXIS 240K. Every illustration, every part number, every compatibility note is factory-original. No aftermarket shortcuts. No translator errors.

What You Get in These 694 Pages

This is a Parts Catalog, not a workshop manual. It’s for ordering the exact bolt, seal, or hose assembly that came off the line. The table of contents alone runs from FRAME to CAB GROUP, with sections like ENGINE, PUMP DEVICE, SWING DEVICE, CONTROL VALVE, and ELECTRIC PARTS (A) through (F). Each section breaks down into sub-assemblies with part numbers and quantities. Need the counterweight for a ZAXIS 240H? There are two entries: 6.1T and 6.5T, each with its own model code. That level of detail saves a trip to the dealer counter.

Does It Cover Your Specific Model?

Page 3 of the catalog shows the model code system. <230> means ZAXIS 230 and ZAXIS 230LC. means ZAXIS 240H and ZAXIS 240LCH. means ZAXIS 240K and ZAXIS 240LCK. <250> covers the larger ZAXIS 250 series (not your machine, but included for completeness). If you own a ZAXIS 240K, every page with in the header applies. No guesswork. The catalog also flags track types: STD, LC, Narrow LC. And it marks European specs separately (EU1, EU2). Order the wrong part because you skipped this page? That’s on you.

Parts Breakdown: From Engine to Cab Group

The ENGINE section alone covers engine support brackets, oil filter piping, intercooler piping and net, radiator with support and cover, reserve tank, air cleaner assembly (with support and parts), pre-cleaner parts, muffler, fuel tank and support, fuel piping, fuel feed pump, and fuel double filter. That’s about fifteen sub-sections for the powerplant. Then you get pump device and support, swing device, oil tank options (separate for <230,H,250> and ), six sections for main piping, and a full set of pilot piping labeled A through J. Every pipe routing, every clamp, every O-ring is drawn and numbered.

Further in, you’ll find the cab group with 20+ sub-sections: cab variants for different track widths and guard packages, power window parts, window washer, sunshade, floor parts, seat options (cloth, vinyl, suspension, air-suspension with heater), seat belts, and all the interior covers. The electrical sections cover control unit, switch box, satellite communicator, multiple head lamp configurations, boom light harnesses, horn, swing alarm, travel alarm, and the full air conditioner system (including condenser net, heater piping, duct, rear box variations). If you’re troubleshooting a cab electrical issue, this is the map.

Ordering Parts Correctly the First Time

Page 5 of the catalog gives you the legend for the service codes. W means local machining required – do not order that part unless you have the equipment. H means precision part – send it to the dealership. D means assembly only – do not try to buy the internal piece separately. K means the part is in a service kit. R means the quantity varies per machine (shims, adjusters). OP means optional – not standard. OS and US are oversize and undersize. Compatibility codes: Y is unconditional interchange, I means you can substitute but not the reverse, T means matched set, P means superseded – stop ordering the old part. This is the kind of information that keeps you from buying a part that physically fits but kills your seals in a week.

Why Factory Documentation Beats Aftermarket

I’ve had aftermarket parts catalogs that list a “universal” hydraulic filter that fits six different machines. That doesn’t work when you need the specific return filter for a ZAXIS 230LC with a 6.1T counterweight. The factory PDF gives you exploded views of every assembly with the exact Hitachi Sumitomo part number printed next to each item. No renumbering. No “compatible with” nonsense. If you’ve ever tried to match a wire harness from a third-party drawing and ended up with a short, you know why OEM matters.

Related manuals you might need: HITACHI ZAXIS 230 240 Parts Catalog is the one you’re looking at. For engine overhaul specs, grab the HITACHI ZAXIS 200/225/230/270 Workshop Manual. And if you run a bigger rig, the Hitachi Sumitomo ZAXIS850-3 Series Parts Catalog – 451 Pages will keep your 850 running.

Can I use this catalog to rebuild the engine?

No. This is a parts catalog, not a service manual. You get part numbers and exploded views, not torque specs or procedures. For engine rebuild steps, get the workshop manual for your model.

How do I know which model variation my machine is?

Check the product identification number (PIN) on your machine. Page 3 of the catalog explains how to read the serial number prefix. The first six digits of the PIN tell you the model code. For example, if your PIN starts with 010001 or higher, the catalog applies. The book also lists track types and regional specs (EU1, EU2, STD). If you have a ZAXIS 240LCH with a 6.1T counterweight, look for the marking on each page. Every illustration header shows which models it covers. If you don’t see on that page, that part doesn’t fit your machine. I’ve had customers order 5.4T counterweight parts for a 6.1T machine because they skipped the header verification. Don’t be that guy.
