FIAT Kobelco K904-II, K904L-II 2005 Parts Catalog

If you’ve ever ordered a part for a K904-II based on a third-party list and got the wrong one, you know the headache. A misidentified seal or bracket means the machine sits while you wait for the correct replacement. This FIAT Kobelco K904-II, K904L-II 2005 Parts Catalog takes that guesswork out. It’s the same binder the dealer parts counter uses – 504 pages of factory diagrams and part numbers straight from Kobelco Construction Machinery America, LLC. Printed in the U.S.A. under book number S3YW1502-03. No reprint, no aftermarket compilation. Just the original OEM documentation.

What’s Inside the 2005 FIAT Kobelco K904-II Parts Catalog

Every section of the machine is broken down into exploded-view illustrations. The catalog starts with machine serial number identification – page 3 shows where to record your K904-II (serial YW-1119~) or K904L-II (serial LX-1526~) numbers. Then it dives into assemblies: upper frame, counterweight, reduction unit, fuel tank, cab and stairs. Each component group has its own index. Need the part number for a fuel filter element? It’s under the fuel tank section, group 515-04. The OCR excerpt shows the exact TOC structure – no generic categories, only Kobelco’s original numbering system.

Why an OEM Catalog Beats Aftermarket Lists

Aftermarket catalogs love to renumber parts or skip supersessions. This manual carries the manufacturer’s own part codes, so what you see is what bolts onto the machine. The copyright is 2005, so it covers the production run for those model years. If a part has been updated, the factory would issue a bulletin – but the starting point is always this book. Relying on a third-party list means you inherit their translation errors. Here, the Japanese and English headings are both present (page 5 shows the bilingual format), keeping the reference tight.

Does This Catalog Cover the K904L-II as Well?

Yes. The title explicitly lists both K904-II and K904L-II. The catalog splits them by serial number range in the front matter. When you order parts, you verify your machine serial and then pull the correct diagram. The L-model variations (likely longer undercarriage or different counterweight) are accounted for in separate groups like counterweight assembly for gain vs. silence configurations. You get one binder that serves both, saving you from buying two separate books.

7 Major Systems Covered in the Parts Breakdown

The catalog arranges everything into groups. From the table of contents you’ll find: Upper Frame (511), Counterweight (511-02 through 511-05), Reduction Unit (511-06), Back Mirror (514), Fuel Tank (515), Cab & Stairs (521-01 through 522-02), and more. Each group contains sub-assemblies. For example, the Cab group 521 has three sub-sections: cab assembly, instrument panel, and instrument panel assembly. Every bolt, seal, and hose clip gets its own callout on the diagram and a corresponding part number in the list. No guesswork about what fits where.

Get the Right Part Number the First Time

When you’re under a deadline, you can’t afford to cross-reference three different websites. Open this manual to the group that matches your machine – the numbers in the diagram match the list. Write down the part number, call your dealer, and move on. The front page includes space to record your machine serial and engine serial, a practice that saves mistakes when ordering. The catalog also includes notes on how to read the parts list (see page 5 for examples). Stick with the factory numbering and you’ll avoid returns.

Source Validity: Factory versus Third-Party Parts Catalogs

This isn’t a scanned version of a manual that someone assembled from memory. Book form number S3YW1502-03 is Kobelco’s own publication. The copyright line reads “Copyright © 2005, Kobelco Construction Machinery America, LLC. All Rights Reserved.” That’s the same legal authority as the paper manual sitting in a dealership parts department. Aftermarket documents tend to omit supersession notes or mix up left/right orientation. With this, you’re working from the source that dealers use to stock their shelves.

Frequently Asked Questions

Is this the same as a service repair manual?

No, this is a parts catalog for ordering correct parts.

How do I decode the part numbers in the catalog?

The catalog uses a structured numbering system where each part number corresponds to a specific assembly. Look at the diagram callout number, then find the matching line in the parts list. The list includes the part number, description, and quantity per assembly. If a part has been superseded, you’ll see a notation in the list. Always reference your machine serial number (recorded on page 3) because some groups differ by serial range. The front matter explains the format – groups are numbered like 515-04 for fuel filter. Cross-check with the illustration before ordering.
