Hitachi Sumitomo ZAXIS 270, ZAXIS 270LC, ZAXIS 280LC, ZAXIS 280LCN Parts Catalog

Nothing burns shop time like ordering the wrong part because you guessed from a blurry online photo. I’ve seen a $20 seal turn into a week of downtime waiting for the correct one. That’s why this Hitachi Sumitomo ZAXIS 270, ZAXIS 270LC, ZAXIS 280LC, ZAXIS 280LCN Parts Catalog exists – a 588-page factory document that shows you exactly which part number goes where, on which machine, by serial number. No aftermarket guesswork, no reprints with smudged numbers.

This isn’t a repair manual. It’s the parts bible. You look up the exploded diagram, read the service code (R for shims, D for non-serviceable assemblies), check the applicable serial range, and order. Done. The Parts Catalog covers every assembled group on the machine – from the Engine support brackets to the Fuel double filter, the swing device, the cab guard, the whole upperstructure. You want the exact O-ring for the center joint? It’s in here with the part number and the quantity needed.

Engine and Fuel System Coverage

The catalog breaks down the Engine mountings, oil filter piping, intercooler piping, radiator, and air cleaner entirely. Under the Fuel section you’ll find the tank, support brackets, feed pump, double filter, and all piping – with separate pages for return, suction, and drain lines. Every clip, every hose, every bolt has a line item. The OCR excerpt confirms the “FUEL TANK” and “FUEL PIPING” chapters are there, plus “FUEL FEED PUMP” and “FUEL DOUBLE FILTER”. If you need to track down a leak in the delivery piping, the break-out drawings show each component.

3 Reasons to Choose OEM Documentation

First, the serial number lookup. Right on page 3 of the PDF you get a blank form for product identification number and engine serial. The catalog uses “applicable machine number” codes – a D prefix indicates a change date (e.g. D03/09 means September 2003 onward). An H prefix refers to the machine serial. You match your machine’s PIN against the table and pull the correct part. Aftermarket catalogs skip this entirely.

Second, the service codes. Every part gets a letter – W for field modification needed, H for precision parts (don’t disassemble), K for kit inclusion, S for service-only parts. You need a shim? Look for the R code. That level of detail saves you from ordering a non-serviceable assembly when you only needed a subcomponent.

Third, the page count. 588 pages of pure exploded-view drawings and part numbers. No filler. Every page is one group – “BOOM FOOT PIN”, “CENTER JOINT PARTS”, “SWING DEVICE”, “CONTROL VALVE”. You flip to the group, find the reference number, cross it to the part number list. That’s it.

Who Needs This Catalog?

Any shop or owner running a ZAXIS 270, ZAXIS 270LC, ZAXIS 280LC, or ZAXIS 280LCN. If you’re a home garage mechanic doing your own undercarriage work, this saves you from buying a hydraulic line that doesn’t fit the LC track frame. If you run a 6-bay shop like mine, you hand this to the parts guy so he stops calling you every five minutes to ask “is this seal left or right side?” The answer is right there in the catalog, grouped by assembles like “PILOT PIPING (A)” through (J).

The document covers both standard and narrow LC variations. Look for tags like “<270>” for the 270 models, “<280>” for the 280LC and 280LCN, and “[NA]” for North American spec. That’s factory-level granularity. You won’t get that from a third-party PDF.

FAQ

Does this catalog include torque specs for installation?

No. This is a parts catalog, not a repair manual. It lists part numbers, quantities, and service codes. For torque values you need the separate shop manual.

Can I use this for the ZAXIS 200 series?

No. This catalog is specific to ZAXIS 270, 270LC, 280LC, and 280LCN. The chassis, engine options, and piping are different on earlier models.

How do I find a part number if I only know the description?

Use the parts number index at the back of the manual. It lists every part number alphabetically. Or browse the group that matches your machine area – e.g., for fuel system go to the FUEL TANK section. The exploded drawing gives a reference number, then you match it to the table.

What do the service codes like “D” or “H” mean?

D means the part was changed at a specific date – look for a date after “D” (e.g., D03/09). H means the part is tied to a machine serial number – you need the serial from the component nameplate. K means the part is included in a service kit.

I’ve been wrenching since before these machines were built, and I’ll tell you straight: if you’re working on a Hitachi Sumitomo excavator, you need the factory parts cross-reference. Access the Factory Manual and keep it on the shop tablet. One lookup and you’re done guessing.
