FIAT Kobelco SK250-6ES, SK250LC-6ES 2004 Parts Catalog

I’ve seen too many guys pull a part off the shelf, slap it on, and then spend an afternoon chasing a leak because the number was off by one digit. That’s exactly why this 634-page OEM parts catalog exists. It covers the FIAT Kobelco SK250-6ES and SK250LC-6ES hydraulic excavators from the 2004 model year. If you’re wrenching on one of these machines and you don’t have the factory part numbers and exploded views, you’re working blind. This isn’t a repair manual – it’s the parts bible that tells you which coupling assembly, which capscrew, which seal actually belongs on your machine. I’ll show you what’s inside and why you need it on your bench.

Machine Serial Numbers and Parts Identification

Every machine gets a unique serial number. Page 1 of this catalog clearly states the applicable serial number ranges: SK250-6ES LQ11-05201~ and SK250LC-6ES LL11-04001~. Before you order a single bolt, you need your machine number and engine number written in the spaces on page 3. The Japanese and English instructions on that page are there for a reason – record it once, and you save yourself the headache of a wrong part. The catalog is built around these serial number breaks. Miss yours, and the part listed may not fit. Period.

How to Read the Parts Table: ITEM, Part No., QTY

Page 5 explains the layout with a sample table. Each row gives you the ITEM reference (like A1, A1-1), the PART No. (e.g., YR30P00003F1), the part name in English and Japanese, the quantity required per assembly, and a REFERENCE column for notes like “SEE(C.P.M)”. The exploded figures are numbered (FIG 001-50-1, etc.) so you can visually match the callout to the line item. I’ve seen guys skip the ITEM column and order by description alone – that’s how you end up with a coupling hub instead of a coupling assy. Use the figure, match the ITEM, verify the part number. That’s the process.

Ordering Parts: The Six Required Items

When you call your dealer, they aren’t going to guess what you need. The catalog lists exactly what information to have ready: (1) machine type, (2) machine number or engine number, (3) part number, (4) part name, (5) quantity, (6) your address and shipping method. I’ve watched mechanics waste an hour on the phone because they didn’t have the machine number. Write it down from the ID plate before you even open the catalog. This section on page 5 is short but it’s the difference between a five-minute order and a return. For related excavator parts manuals, check out the FIAT Kobelco ED150, ED150-IE 2013 Parts Catalog OEM and the FIAT Kobelco ED150, ED150-2 2009 Parts Catalog OEM Manual. Both follow the same factory format.

Engine Parts Are in a Separate Chapter

Don’t waste time flipping through the main sections looking for engine components. The preface on page 5 states: “For engine parts, refer to the Chapter ‘ENGINE’.” That chapter is not included in this parts catalog – it’s a separate manual. If you need pistons, rings, or gaskets for the engine, you need the engine-specific parts book. This catalog covers everything else: hydraulics, undercarriage, boom, arm, bucket, cab, electrical. Keep the engine manual on the shelf next to this one. The FIAT Kobelco LK650-II 1992 Parts Catalog – OEM Factory Specs also follows the same separation.

3 Reasons to Use the OEM Catalog Over Aftermarket

First, the part numbers in this catalog are direct from FIAT Kobelco’s 2004 release. Aftermarket catalogs merge numbers across model years and often drop supersessions. Second, the exploded views show exact hardware – spring pins, capscrews, and socket bolts – with dimensions. An aftermarket list might say “bolt, 6 pcs” but doesn’t tell you the thread size or length. Third, the revision note on page 5 says that changes are described in revised editions. OEM parts catalogs get updated; third-party reprints freeze the data at the print date. If you care about fit, use the factory source. For more background on why OEM documentation matters, see Automotive Industry Overview. The Automotive Industry Overview also covers parts standardization.

Does This Catalog Cover Your Machine Serial Number?

Check your serial plate. If your SK250-6ES has a number starting LQ11-05201 or higher, or your SK250LC-6ES starts LL11-04001 or higher, then this catalog applies. If your machine is older than that serial break, the part listings may not match. The preface warns that the catalog contains parts for “all machines having machine numbers following the numbers mentioned on the face,” but also includes parts for specifications other than those delivered. When in doubt, compare your existing part to the exploded figure before ordering.

Can I use this catalog to order engine parts?

No. Engine parts are in a separate chapter. This catalog covers everything else – undercarriage, hydraulics, cab, boom, etc. You need the dedicated engine parts manual for pistons, rings, gaskets, and related components.

Do I need the machine serial number to order parts?

Yes. The catalog is organized by machine serial number range. Without the serial number from the machine ID plate, you risk ordering the wrong part. See page 3 for where to record it, and the preface explains which serial numbers are covered. Always verify the part number matches the spec plate. If you skip this step, you’ll likely get a part that doesn’t fit, and you’ll pay return shipping.

This catalog is a tool, not a decoration. Put it on your bench, open it to the figure for the assembly you’re working on, and read the part numbers off the page. That’s how you keep your machine running without wasted time or mismatched parts. You want the real thing. Access the Factory Manual from the link above and keep it in your shop binder.
