Hitachi Sumitomo ZAXIS 600, ZAXIS 600LC, ZAXIS 650H, ZAXIS 650LCH Parts Catalog – 468 Pages OEM

I’ve seen more parts orders go wrong because a guy pulled a number off a worn-down casting than I’ve seen hot days in San Antonio. If you’re tearing down a ZAXIS 600 or 650H, you need the factory diagram, not a photo someone took on a dirty floor. This is the OEM Hitachi Sumitomo ZAXIS 600, ZAXIS 600LC, ZAXIS 650H, ZAXIS 650LCH Parts Catalog — 468 pages of exploded views, part numbers, and interchange codes direct from the builder.

Engine and Fuel System Sections – from the 468-Page Breakdown

Turning to the engine section first. This catalog breaks out the Engine into two sub-sections: and . That matters because the emissions hardware is different, and the part numbers for injectors and gaskets don’t cross. You get separate exploded views for each. After that, the Fuel system gets its own section: FUEL PIPING, FUEL TANK, FUEL FEED PUMP, and FUEL DOUBLE FILTER. Every fitting and filter housing is shown with its own part code. If you’re rebuilding a fuel system on a ZAXIS 600LC, you need to see the piping routing diagrams — that’s on page 47 of the PDF bookmarks (the FUEL PIPING page). No aftermarket source is going to show you the factory clip positions.

Transmission (Pump) and Swing Device – Two Critical Subsystems

The Transmission section covers the pump drive (TRANSMISSION (PUMP)) and its support bracket, including the damper coupling parts. Then the SWING DEVICE splits into right and left, each with two pages of drawings. Those orbital motors have seal kits that are specific to the serial number range — the catalog lists the service code ‘H’ for precision parts that you don’t touch without factory training. If you’re ordering a swing motor rebuild kit for a 650LCH, this catalog tells you exactly which part number to use. The PILOT PIPING section (7 sub-pages) shows every hydraulic line from the lock lever to the control valves.

That’s the kind of detail you get.

Undercarriage: Track Frame, Travel Device, and Track Options

On the undercarriage side, the catalog covers TRACK FRAME (STD. TRACK) and TRACK FRAME (LC TRACK) separately. That means if you have a ZAXIS 600LC with long tracks, you’re not cross-referencing from a standard machine. The TRAVEL DEVICE and TRANSMISSION (TRAVEL) sheets list all the planetary gear and motor components. You also get FULL LENGTH TRACK GUARD drawings for each track variant — STD, LC, and the 650H/650LCH specific guards. Track link options include 600G, 750G, and 900G for both standard and LC frames. That’s three different link pitches, each with its own set of pins and seals.

Front-End Attachment: Boom, Arm, and Bucket Codes

For front-end work, this catalog lists STD. BOOM 7.6M, HD BOOM 7.6M, BE BOOM 6.6M, and LONG BOOM 9.2M. Arms go from 2.9M to 5.2M. Each gets its own section with separate part numbers for bushings, pins, and cylinder mounts. Buckets include standard, rock, and ripper types — eight different capacities from 1.5 to 3.3 cubic meters (JIS 94 rating). The FRONT PIPING section (STD. B) shows the exact routing for the hose bundles inside the boom. If you’ve ever had a customer complain about a leaky boom hose, the factory diagram saves you an hour of tracing lines.

OEM Source vs Aftermarket – Why This Catalog is the Only One to Trust

I’ve burned enough time on third-party parts lists that swap out a bolt for something that looks close but isn’t the same grade. This catalog is printed from the Hitachi Sumitomo master database. The compatibility codes (I, P, T, Y) tell you exactly whether a part can be replaced by a newer number, or if you must use the superseding set. The service codes (W, H, D, K, R, S, Z, OP, OS, US) remove all guesswork. That’s not something you get from a photocopied aftermarket book.

Frequently Asked Questions

Does this catalog include engine part numbers for both US and EU models?

Yes. The ENGINE section has separate subsections for and . Part numbers for the Isuzu BB-6WG1XQA-01 are listed separately.

How do I read the compatibility codes in the catalog?

The manual uses a system of letters: I (interchangeable one way), P (prohibited – use superseding part), T (group replacement required), and Y (fully interchangeable). These codes are explained on page 5 of the original document along with service codes for special handling. You must understand these before ordering, or you’ll end up with a part that doesn’t fit despite having the same nominal dimensions. The code applies to the specific serial number range of your machine, so always check the APPLICATION MODEL column.

Is there a parts index at the end?

Yes. The back of the catalog includes a numerical parts index sorted by part number. New parts are marked with an asterisk (*).

Can I use this to order replacement hydraulic hoses?

Yes. The catalog shows hose assemblies in the MAIN PIPING and PILOT PIPING sections. Each hose has a part number and length specification. You can order factory-made hoses or use the numbers to get equivalent assemblies from a hydraulic shop.

If you’re working on a ZAXIS 600, 600LC, 650H, or 650LCH, having the factory catalog means you’re ordering the right part the first time. Stop guessing and access the factory manual.
