FIAT Kobelco K912A 2005 Parts Catalog – OEM Factory Breakdown

You pulled a part number off a third-party site and got the wrong swing motor seal. Now the machine is down, the rental is costing you, and the customer is calling every hour. That’s why I keep the FIAT Kobelco K912A 2005 Parts Catalog on the shelf — not some aftermarket knockoff. This is the factory-issued 252-page document that Kobelco printed in 2005 for the K912A hydraulic excavator (applicable to LC-2003-2016 serial number range). It gives you exploded views, OEM part numbers, and assembly groupings that you won’t find in a generic PDF scraper. Every section is organized by machine structure — upper deck, main frame, swing motor, counterweight, engine, hydraulics — so you can zero in on exactly what you need without flipping through irrelevant pages.

What’s Inside: 252 Pages of Parts Breakdown

The catalog splits the machine into two main sections: TOP MODEL K912A and UPPER DECK. Under TOP MODEL you get the main frame assembly (with or without lift cylinder), swing motor assy, counterweight assy, engine assy, fuel tank assy, oil tank assy, lubrication devices, ballast, attachment cylinders, outrigger assy, and bucket cylinder assy. The UPPER DECK section covers cover assy, cylinder assy (without cylinder), hydraulic oil, main swing motor assy, upper frame assy, and so on. Each assembly has its own page with a figure number, part description, quantity, and notes. The table of contents starts with a foreword (page 5) that explains how to read the combination chart for regional variations — North America, Australia, Canada, Europe, and worldwide totals. If you need a part for a Canadian-spec machine, the catalog lists a separate total for that region. This isn’t a generic list; it’s a regionalized OEM document.

Upper Deck and Main Frame: Ordering the Right Assembly

You see the “Main Frame Assy (Lift Silent Type)” and “Main Frame Assy (Without Cyl)” listed separately. Those are two different assemblies because Kobelco offered a silent type frame with vibration damping and a standard frame without the lift cylinder. If you order the wrong one, the mounting holes won’t line up. The catalog gives you the part number for each assembly, along with the individual components inside it — so you can either order the whole assembly or just the bracket you need. Same for the swing motor assy: it includes the motor, swivel, and mounting bolts. Page 73 (approximate) shows the swing motor breakdown. Don’t guess — look it up.

Engine Assy and Hydraulic Components: Getting the Correct Part Numbers

The engine assy section covers the complete power unit — block, head, injection pump, alternator, etc. But note: the manual states that engine parts are covered separately in the engine parts diagram (see the foreword). So if you need a piston ring, you order from the engine-specific catalog, not this one. The hydraulic system — oil tank assy, swing motor assy, hydraulic oil, ballast — is all here. Lubrication devices and ballast are grouped separately because they affect machine stability. For hydraulic line parts, the exploded view shows O-rings, fittings, hoses, and their part numbers. Cross-check the serial number on your machine to the LC-2003-2016 range listed on page 1.

Why Use an OEM Parts Catalog Instead of Third-Party?

Third-party catalogs often transpose part numbers or miss supersessions. This OEM catalog from 2005 was printed by Kobelco Construction Machinery America, LLC — copyright 2005. It’s the same document the dealer parts counter uses. You get the original part numbers, the exact exploded views, and the correct count of bolts per assembly. If you’re rebuilding a K912A, this is the only reference that matches the machine as built from the factory. For related models, check the KOBELCO K912A K912ALC 1987 Parts Catalog – Section: Cab Group or the FIAT Kobelco ED150, ED150-IE 2013 Parts Catalog OEM for newer machines. The FIAT Kobelco ED150, ED150-2 2009 Parts Catalog OEM Manual also follows the same factory print standard.

How to Use This Catalog for Your K912A

Start by writing down your machine serial number and engine serial number in the spaces provided on page 3. That’s the first step — don’t skip it. Then use the table of contents to find the assembly group you need. Look at the combination chart in the foreword to see if your machine is North American, Australian, Canadian, European, or worldwide spec. Each regional total has its own page range. Find the figure number for your assembly, turn to that page, and read the part numbers. When ordering, give your dealer the part number, description, quantity, machine model, and serial number. If you’re working in a home garage, this catalog is still the best reference because it shows exactly how the machine was assembled. Need reference on internal combustion engine fundamentals? The Internal Combustion Engine page helps understand engine components. For broader automotive industry context, see Automotive Industry Overview.

Frequently Asked Questions

Does this catalog include torque specifications for the K912A?

No. This is a parts catalog, not a service manual. It shows part numbers and exploded views, not torque values or repair procedures. You need the separate service manual for that information.

Can I use this PDF on a tablet in the shop?

Yes. The PDF is printable and searchable on any device. Keep it oil-free by using a screen protector.

What if my machine has a serial number outside the LC-2003-2016 range?

The cover page says it applies to K912A models from LC-2003-2016. For machines outside that range, the parts may differ. Check the serial number on your machine’s ID plate against that range before ordering.

Are there separate totals for different countries in this catalog?

Yes. The table of contents lists separate total pages for North America, Australia/New Zealand, Canada, Europe, and worldwide. Each region may have different component configurations. Always use the total section that matches your machine’s destination market to get the correct part numbers.

If you own a K912A backhoe loader and want to stop ordering wrong parts, get the factory document. Access the Factory Manual now and start matching part numbers to your machine’s VIN. It’s the same 252-page catalog that Kobelco parts dealers use — no reprints, no copy errors, just the original OEM data printed in 2005.
