Hitachi Sumitomo ZAXIS 270, 270LC, 280LC, 280LCN Parts Catalog 598 Pages

Description

I’ve been wrenching for 28 years, ASE Master. If there’s one thing that burns my ass, it’s ordering a part that doesn’t fit because someone used a cross-reference from a third-party site. This Hitachi Sumitomo ZAXIS 270, ZAXIS 270LC, ZAXIS 280LC, ZAXIS 280LCN Parts Catalog is the real deal – factory pages, 598 of them, scanned from the original binder. No aftermarket shortcuts, no translated part numbers that end up being wrong. You want the exact bolt for the boom foot pin? It’s in here. You need the fuel feed pump part number for a ZAXIS 270? Page 1 of the fuel section. That’s the kind of certainty you get when the OEM built the book.

Hitachi Sumitomo ZAXIS 270/280LC Parts Catalog: Engine and Fuel Sections

Engine parts live under the ENGINE and FUEL TANK headings. You get the full breakdown: ENGINE SUPPORT, OIL FILTER PIPING, INTER COOLER PIPING, RADIATOR, AIR CLEANER, PRE CLEANER, MUFFLER, FUEL TANK SUPPORT, FUEL PIPING, FUEL FEED PUMP, and FUEL DOUBLE FILTER. Each part number is listed with quantity and compatibility codes. If you’re swapping a fuel filter on a ZAXIS 280LCN, you’ll find the correct double filter assembly under FUEL DOUBLE FILTER. Don’t waste time pulling the wrong part off the shelf – verify with the factory drawing first.

What Makes This Parts Catalog Different From Aftermarket?

Aftermarket parts catalogs often merge multiple models into one generic drawing. This one separates the ZAXIS 270, 270LC, 280LC, and 280LCN with specific <270>, <280>, [STD], [NA], [EU1], [EU2] markings. The boom light harness is different between mono boom and 2P-boom – the catalog lists both under BOOM LIGHT HARNESS. The seat variants (cloth, vinyl, suspension, air-suspension with heater) each have their own pages. If you need a seat belt for a suspension seat on a ZAXIS 270 shipped to North America, the [NA] tag points you to the right part. That level of specificity is why you pay for OEM documentation.

598 Pages of Factory Exploded Views

Every section – from UPPERSTRUCTURE (FRAME, SWING BEARING SUPPORT, CENTER JOINT) to CAB GROUP (CAB, WINDOW GUARD, DOOR LOCK, WEATHER STRIP) – is illustrated with numbered callouts. You don’t guess which bolt goes where. The exploded view shows the order of assembly. The parts list below each drawing gives the part number, name, quantity per machine, and service code. For example, the COUNTERWEIGHT sections are split by weight: 6.1T and 6.5T. If you’re pulling a counterweight to replace a swing motor, you need the correct bolts listed on the counterweight page. The catalog includes all that.

Check the Counterweight and Frame Diagrams

Under FRAME you’ll find the main structure, including the BOOM FOOT PIN assembly. If you’re swapping a center joint on a ZAXIS 280LC, the CENTER JOINT PARTS (UPPERSTRUCTURE) section shows the seals and bearings. The hydraulic piping sections (SUCTION, DELIVERY, RETURN, DRAIN, MAIN PIPING 1-4) are all isolated. Need a specific O-ring for the pilot piping? PILOT PIPING (A) through (J) cover every circuit. This manual is organized so you can find the exact component without flipping through fifty pages of generic diagrams.

Upperstructure: Frame, Swing Bearing, and Center Joint

The upperstructure section alone covers the frame, swing bearing support, boom foot pin, and center joint. If you’re replacing the swing bearing, the parts list includes the bearing itself, retaining bolts, and the support structure. The manual also shows the center joint with its internal seals – critical for preventing hydraulic leaks. Don’t rely on aftermarket manuals that might skip the center joint details. Stick with the OEM file from AutoRepairManuals.

I’ve seen too many techs order the wrong hydraulic line because they trusted an aftermarket cross-reference. This catalog eliminates that risk.

Does this catalog include torque specs for the swing device?

No, it’s a parts catalog, not a service manual.

Can I use this to rebuild the engine?

You can identify every part in the engine and fuel system. The exploded views show assembly order and part numbers for the engine, oil filter piping, inter cooler, radiator, and fuel system. For rebuild procedures like clearance checks and torque sequences, you need the separate engine service manual. But for ordering pistons, rings, gaskets, and fuel lines, this catalog is all you need. The fuel feed pump part number, fuel double filter, and engine support brackets are all listed with factory codes. Combined with a service manual, it’s a complete rebuild package.
