Fiat-hitachi ZAXIS 800, ZAXIS 850H Parts Catalog

If you’re ordering parts for a Fiat-hitachi ZAXIS 800, ZAXIS 850H Parts Catalog and you’re flipping through a generic aftermarket PDF, you’re gambling on fitment and losing billable hours. I’ve seen guys pull a fuel pump out of the box only to find it’s the wrong revision because the third-party drawing skipped the “A HEAVY OIL” variant. This OEM catalog – 650 pages of factory exploded views – gives you the exact part number, supersession, and quantity per machine. No guesswork.

Look, I run a six-bay shop in San Antonio. When a customer brings in a ZAXIS 800 with a blown Engine oil cooler line, I need the OEM breakdown for the ENGINE [STD] [NA] versus the ENGINE [EU] setup. This catalog has both sections. You get the factory diagram for the OIL FILTER PIPING, ENGINE OIL DRAIN PIPING, and the RADIATOR assembly. Every hose clip and gasket shows up with a part number. That’s the difference between a same-day fix and a three-day wait for the wrong piece.

ENGINE [STD] [NA] and ENGINE [EU] – What the Catalog Covers

Two separate chapters list every component bolted to the ISUZU 6WG1 powerplant. You’ll find the ENGINE SUPPORT brackets, the OIL FILTER PIPING routing, and the ENGINE OIL DRAIN PIPING. Page 3 of the catalog shows the engine type and manufacturing number – that’s where you verify your machine’s serial number against the catalog data. Each engine variant gets its own exploded diagram with numbered callouts. No aftermarket rehash.

Fuel System: FUEL TANK, FUEL PIPING, FUEL DOUBLE FILTER

Three dedicated sections handle the Fuel system: FUEL PIPING, FUEL TANK, and FUEL FEED PUMP. There’s even a separate entry for FUEL DOUBLE FILTER (A HEAVY OIL) – that’s the heavy-oil variant you’ll find on machines running high-sulfur fuel. If you’re replacing the FUEL DOUBLE FILTER assembly, the catalog lists the filter head, bowl, and element as individual part numbers. No need to buy a whole kit if only the bowl cracks.

TRANSMISSION (PUMP) – Critical Pump Assembly Breakdown

The Transmission section is labeled TRANSMISSION (PUMP) in the table of contents. It details the pump device, pump device support, and the swing device assemblies. You’ll see SWING DEVICE : RIGHT (1) and LEFT (1) along with their support brackets. Every seal, bearing, and gear is listed. I’ve used this catalog to cross-reference a swing motor seal that was superseded three times – the OEM numbers saved me from ordering a dead part.

Undercarriage and Backhoe Attachments – Track Frames, Booms, Buckets

The UNDERCARRIAGE chapter splits into TRACK FRAME, TRAVEL DEVICE, and track-link variants (650G, 750G, 900G). For the backhoe, you get STD. BOOM 8.25M, HD BOOM 8.2M, BE BOOM 7.1M, and multiple arm lengths – STD. ARM 3.6M up to LONG ARM 5.4M. Bu​cket options include BUCKET 2.8 [JIS 94] through ROCK BUCKET 4.3 and RIPPER BUCKET 1.9. Each attachment has its own front piping diagram. You can order exactly the pin and bushing for your boom type without measuring.

OEM Source – Why This Beats Aftermarket Catalogs

This catalog came straight from Fiat-hitachi’s factory files. The part numbers match what the dealer’s computer pulls. The exploded views show the correct orientation for pilot piping, main piping, and control cables. Aftermarket catalogs often combine the [NA] and [EU] variants into one muddy drawing – this catalog keeps them separate. The CONSOLE COVER [STD] is different from the [NA] cover; the OEM pages make that clear. You also get the compatibility codes (Y, I, P, T) printed right on each page, so you know if a part supersedes or is banned.

If you’re working on a ZAXIS 800 or 850H and need the exact part number for a pilot check valve or a cab seal, this catalog has it. Related manuals you might need: HITACHI ZAXIS 800 ZAXIS 850H Parts Catalog, Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog, and Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs.

Does this catalog include part numbers for the engine?

Yes, the ENGINE [STD] [NA] and ENGINE [EU] sections list every component.

How do I know which part variant fits my machine?

Check the machine serial number against the indicator codes at the top of each page. For example, <800> means ZAXIS 800, means ZAXIS 850H. The [NA], [EU], [STD] tags tell you the regional spec. The catalog also includes compatibility columns: Y means direct swap, I means one-way substitution, P means that part is banned and you must use the alternative listed. If you have a ZAXIS 850H with a European spec cab, look for [EU] in the header – that’s your page. The fuel filter section even splits standard and heavy-oil variants by part number, so you don’t order the wrong filter head. Page 3 of the catalog provides the engine type and manufacturing number to confirm your exact power unit.
