Description

Hitachi Sumitomo ZAXIS 70, ZAXIS 70LC, ZAXIS 80, ZAXIS 80LCK, ZAXIS 80SB Parts Catalog

You’ve got a ZAXIS 80 in the bay with a blown hydraulic line, and the parts guy hands you a generic diagram that doesn’t match the banjo fitting you’re holding. That’s wasted time, wasted money, and a machine down longer than it needs to be. This is the factory Hitachi Sumitomo ZAXIS 70, ZAXIS 70LC, ZAXIS 80, ZAXIS 80LCK, ZAXIS 80SB Parts Catalog – straight from Hitachi, not a third-party re-draw. 644 pages of exploded views, part numbers, and model-specific callouts that tell you exactly which seal goes where.

Engine and Fuel System Coverage

Every section – from the ENGINE mount to the FUEL TANK support and FUEL PIPING – is broken down by model variant. Page 3 shows the model coding: <70> for ZAXIS 70 and 70LC, <80> for ZAXIS 80, for 80LCK, for 80SB. That means when you order a fuel feed pump, you check the SB flag or standard track. The manual includes FUEL DOUBLE FILTER, AUTO VACUUM FUEL DEVICE, and the FUEL FEED PUMP for both standard and SB models. No guessing which pump fits a 80SBLC – the part number is right there.

What This Catalog Covers That Aftermarket Doesn’t

Aftermarket catalogs lump all ZAXIS 70-series into one blob. This factory book separates FRAME <70,80,K>【EU】 from FRAME . It lists center joint parts with blade and without blade. It gives you the COUNTERWEIGHT with hanging seat and without. You need radio (AM/FM) or battery box? Those are separate sections. Even the CAB variations – B-type, HG-type, with guard seat, with vandal hook – all shown. A beginner might think all cabs are the same; this catalog shows you six different CAB sub-sections depending on model and market.

644 Pages of Factory Part Numbers

Every page in this Parts Catalog comes from Hitachi’s own engineering data. That means the part numbers you see have been verified against the serial number ranges printed on page 3 (Serial No. 060001~). The MEMORANDUM page tells you to fill in your machine’s Product Identification Number and Engine Type before ordering. That’s a step most DIY guys skip – but it’s the difference between getting the right main piping and getting something that doesn’t clear the offset boom. The catalog also lists interchangeability codes: Y, I, T, P – so you know if a part supersedes another.

Control Valve and Piping Diagrams

Look at the table of contents – CONTROL VALVE, CONTROL VALVE SUPPORT, SHOCKLESS PARTS, PILOT PIPING (1) through (9). That’s nine separate piping diagrams for the pilot system alone. Each one is model-specific: mono boom, offset boom, swing boom. If you’re swapping a control lever (front & swing) or a travel pedal (R) for offset boom, the drawing shows you the exact bracket and hardware. And because it’s a Parts Catalog, not a service manual, every component is exploded – you see the washers, bolts, and o-rings that hold it together.

How to Use the Parts Catalog

Open it to page 4. It tells you: order parts using model name, PIN, part number, and quantity. For engine parts, refer to the separate diesel engine catalog. For codes like W (field work required), H (precision part – contact dealer), D (assembly only), K (service kit), OP (optional) – they’re all explained. That’s information you need when you’re standing at the parts counter. A beginner will learn that a part marked with “#” means it was added to this catalog for a new device. That’s a level of detail you don’t get from a reprint.

Frequently Asked Questions

Does this parts catalog include engine part numbers?

No. Hitachi lists engine parts in a separate diesel engine catalog. This book covers everything else – frame, hydraulics, cab, electrical, controls – but not the engine internal parts.

Can I use this to rebuild a control valve?

It’s a parts catalog, not a service manual. You get exploded diagrams and part numbers, not step-by-step rebuild procedures. For that you need the service manual. But it will show you every seal and spring in the valve bank.

How do I find the right part for a 80LCK with a blade?

Look at the model indicators on each page – means 80LCK. Check the BLADE PIPING (UPPERSTRUCTURE) section, and the DRAIN PIPING (3) (WITHOUT BLADE) section. The catalog also has CENTER JOINT PARTS (WITH BLADE) specifically for 70,80,K models.

Are there electrical diagrams in here?

There are sections like BATTERY, CONTROL UNIT, ELECTRIC PARTS (A) through (G), and SWITCH BOX. These are parts drawings – connectors, relays, harness clips – not wiring schematics. For troubleshooting circuits you need the workshop manual.
