Fiat-hitachi ZAXIS 600, ZAXIS 600LC, ZAXIS 650H, ZAXIS 650LCH Parts Catalog

I’ve been wrenching on heavy equipment for 28 years, and nothing burns my time—and your money—faster than ordering the wrong part because you guessed at the variation. You pull an injector line, find a different thread pitch than what the aftermarket PDF showed, and now you’re down waiting on a reorder. That’s why I reach for the Fiat-hitachi ZAXIS 600, ZAXIS 600LC, ZAXIS 650H, ZAXIS 650LCH Parts Catalog first. This is the factory document, straight from Hitachi. No third-party redraws, no “equivalent” numbers. 584 pages of OEM exploded views and part numbers that actually match the hardware on the machine.

Page 3 spells out the model coding system. You’ll see <600> means ZAXIS 600 and 600LC, means ZAXIS 650H and 650LCH. The catalog also breaks out NA, EU, and STD (rest of world) spec variants. Miss that distinction and you’ll end up with the wrong cab harness or track guard. I’ve seen it happen.

Engine and Fuel System Breakdowns: Know What Fits

This catalog covers the Engine section with separate listings for STD/NA and EU engine packages. You get the exact part numbers for the oil filter piping, engine oil drain piping, radiator group, and the complete Fuel system—tank, feed pump, double filter, and optional heavy-oil filter. If you’re working on a machine with the Isuzu BB-6WG1X, you’ll need the separate engine parts catalog for internal engine parts, but everything bolted to the block is here. The fuel piping chapter alone saves you from chasing down a mis-routed hard line.

Transmission and Pump Components: Don’t Guess, Verify

The Transmission section is split between the pump device and the travel device. The catalog labels each part as W (local machining needed), H (precision part – send to dealer), or D (assembly-only replacement). Page 4 of the foreword defines all the service codes. I keep that page dog-eared. If you see an “H” code next to a swing motor component, you don’t try to overhaul it in the field—you order the assembly. That’s not opinion, that’s the factory instruction.

Undercarriage and Track Options: STD vs LC

ZAXIS 600 and 650H run standard track frames; the 600LC and 650LCH get long-track frames. This catalog has separate chapters for each: track frame, track guard, full-length guard, front idler, adjuster, upper/lower rollers, and track links in 600 mm, 750 mm, and 900 mm gauge widths. You’ll also find the swing bearing and center joint. Ordering a set of rollers? Cross-check the (LC TRACK) indicator on the page header. I’ve watched guys bolt a standard travel piping cover onto an LC frame—doesn’t fit.

Front-End Attachments: Boom, Arm, and Bucket Options

Seven boom variants are listed: standard 7.6 m, HD 7.6 m, BE 6.6 m, and a 9.2 m boom, plus separate arm lengths from 2.9 m to 5.2 m. Bucket capacities range from 2.0 m³ to 2.9 m³, including a rock bucket. Each attachment has its own exploded view with part numbers. The interchangeability codes (Y, I, T, P) tell you whether a newer revision supersedes the old part without modification. That info saves you from buying an obsolete seal kit.

Source Validity: OEM Factory Print, Not a Rehash

This is the original Hitachi PI7P-1-4 Parts Catalog, printed for serial numbers 004001 and up. The PDF you access is a direct scan of the factory publication. No third-party transcription, no re-drawn diagrams. Compared to aftermarket parts lists, this one shows the exact support piping, bracket revisions, and regional variations (e.g., [NA] console cover, [EU] overload alarm system). The Automotive Industry Overview doesn’t help you here—you need the factory source.

FAQ

Does this catalog include engine internal parts like pistons and liners?

No. The foreword states engine parts are in a separate diesel engine catalog. This book covers everything bolted to the engine, plus fuel and intake systems.

How do I tell which track frame my machine uses?

Check the serial number plate. If it’s a ZAXIS 600LC or 650LCH, you have an LC track frame. The catalog uses (LC TRACK) markers on each undercarriage page.

What does the symbol “K” mean in the service code column?

K means the part is included in a service parts kit. You order the kit, not the individual component.

Can I use this catalog to order parts for a ZAXIS 650H with a cab that was originally built for the European market?

Yes, but you must watch for [EU] designators in the cab section. The catalog lists separate cab parts for [STD, EU] and [NA] variants. If your machine has an EU-spec cab, use the [EU] pages for the control unit, monitor, and radio. Ignore that and you’ll get the wrong wiring harness.

Stop burning billable hours on parts that don’t fit. Access the Factory Manual now and keep a copy on your shop tablet or print the relevant pages for the job. When you’re pulling a pump or rebuilding an undercarriage, having the OEM part number in hand is the difference between a one-day job and a three-day wait.
