Fiat-hitachi ZAXIS650LC-3, ZAXIS670LCH-3 2006 Parts Catalog

Ordering parts for a ZAXIS650LC-3 or ZAXIS670LCH-3 without the factory breakdown is throwing time and money in the trash. You get a mislabeled bin, a part that looks right but doesn’t match the serial number, or a gasket that’s for a different cab spec. This Fiat-hitachi ZAXIS650LC-3, ZAXIS670LCH-3 2006 Parts Catalog gives you 391 pages of official Hitachi part numbers, exploded views, and compatibility codes. Engine, fuel, hydraulic, undercarriage — it’s all in here. No aftermarket guessing.

I’ve been wrenching since the 90s and seen too many jobs stall because a mechanic used a third-party parts list that got the revision wrong. This catalog was printed by Hitachi Construction Machinery in 2006. It covers serial numbers starting at 020001. The binding is solid, the diagrams are clean. You get the same info the dealer uses.

Engine and Fuel Piping: From Muffler to Fuel Tank

Two sections you’ll turn to first: Engine and Fuel. The ENGINE chapter includes the block, support, oil filter piping, and side branch piping. The FUEL PIPING section maps every line from tank to pump. Need a specific fuel return line for a <650> machine? Look under FUEL PIPING. The diagram shows the part number and the quantity per machine. For the ZAXIS670LCH-3 variant, check the <670> indicator at the top of the page. Every hose, clamp, and bracket is numbered. If you’re replacing a fuel line on an older machine, this is what you need to get the right bend and fitting.

Also covered: INHALATION PIPING, EXHAUST PIPING, and the MUFFLER. The AIR CLEANER section shows the housing and filter elements. Page numbers are listed in the CONTENTS, but I’ll tell you this: once you have the catalog, the index gets you there fast.

Decoding the Compatibility Codes: <650>, [STD], and [NA]

Hitachi printed three regional spec codes in this catalog. <650> means ZAXIS650LC-3. <670> means ZAXIS670LCH-3. [NA] is for North American machines. [EU] is for European. [STD] applies to all other territories. Look at the top of each page. If you see <650> only, that part is exclusive to the 650LC-3. If you see both <650> and <670>, the part fits both. This is critical when ordering. I’ve had guys grab a part marked [STD] and try to bolt it onto a [NA] machine — doesn’t always work. The catalog also uses service codes like ‘H’ for precision parts that must be dealer-replaced, ‘D’ for parts that can’t be swapped individually, and ‘Y’ for parts with full interchangeability. Read the FOREWORD (page 4) for the full legend.

Upperstructure Sections: Frame, Cab, Control Valve, and More

The UPPERSTRUCTURE chapter is massive. It starts with the FRAME (three sub-sections), the COUNTERWEIGHT (11.1t), then ENGINE support, cooling, and hydraulics. You’ll find the entire hydraulic control system: PUMP DEVICE, SWING DEVICE (left and right), CONTROL VALVE, PILOT PIPING (ten sub-sections!). Need the fan drive piping? It’s in there. The CAB section includes the monitor, radio options (Japan, NA, EU/Asia/Oceania), and air-conditioner components. For electrical troubleshooting, the ELECTRIC PARTS sections (1 through 4) show the wiring and controller locations. The CONTROL UNIT and ENGINE CONTROLLER are listed separately. If you’re chasing a no-start on a ZAXIS650LC-3, check the ENGINE STOP SWITCH and the sensor block. Those are in this catalog.

Also included: GPS parts, rear camera, head lamps (multiple variants), rotating beacon, motion alarm. Everything is exploded with numbered callouts.

Undercarriage: Track Frames, Rollers, and Travel Device

UNDERCARRIAGE covers the TRACK FRAME, TRACK GUARD (including full-length guard), SWING BEARING, TRAVEL DEVICE, FRONT IDLER, ADJUSTER, UPPER and LOWER ROLLERS, and three track-link options: 650mm, 750mm, and 900mm gauge. Each track-link section has its own part numbers. The CENTER JOINT and TRAVEL PIPING are also diagrammed. If you’re rebuilding the undercarriage, you need this catalog to match the roller spacing and track chain pitch. Don’t trust aftermarket cross-references. Use the OEM numbers.

Why OEM Documentation Beats Third-Party Catalogs

Third-party parts catalogs often miss the regional shifts. I’ve seen a catalog list a part number that was superseded and not show the interchange. This Hitachi document prints the compatibility codes and interchange notes (Y, I, T, P) directly on the page. The MEMORANDUM section (page 2) includes a table for you to record the machine serial number and engine type. For the engine itself (AH-6WG1XYSA-02 on the 650LC-3), Hitachi says in the FOREWORD to use the separate engine parts catalog. That’s honest — they don’t try to cram the engine internals into this book. Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog covers a related series. If you need a smaller machine, check the Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs. For the bigger 500-class, the Fiat-hitachi ZX500LC, ZX500LCH Parts Catalog – 464 Pages is available. This catalog sits on my bench next to the service manual. For general reference on why OEM standards matter, the Automotive Industry Overview is a starting point, but this parts catalog is the real tool.

Bottom line: if you own or work on a ZAXIS650LC-3 or ZAXIS670LCH-3, this 391-page 2006 Parts Catalog saves you from ordering the wrong hardware. Access the Factory Manual from AutoRepairManuals and keep it on your laptop or tablet. Your parts manager will thank you.

Frequently Asked Questions

What does the service code ‘H’ mean in this catalog?

It indicates a precision part. For dealer repair only.

Can I use this catalog to order parts for a ZAXIS670LCH-3 with a serial number outside the range printed on the cover?

The catalog covers serial numbers from 020001 onward. If your machine has a lower number, some parts may have been superseded. Check the ‘D’ (date) and ‘F’ (front attachment) compatibility codes in the part list. For example, a part marked ‘D03/09’ means it was introduced in September 2003. If your serial is earlier, you may need the predecessor part listed in the alternative parts column. Hitachi includes interchange codes ‘I’ and ‘Y’ to help you cross-reference. I still recommend verifying with a dealer if your serial is pre-020001, but this catalog covers the majority of production units for both models. Also, engine parts require the separate engine catalog — don’t expect piston rings or bearings here.
