FIAT Kobelco K904C, K904CL, K904SS Parts Catalog

You’ve got a backhoe torn down on the shop floor. The fuel tank is off, and you’re staring at a pile of brackets and hoses. Without the right part numbers, you’ll order the wrong stuff, wait a week, and eat the restocking fee. This is why a factory parts catalog isn’t optional — it’s the difference between a job that pays and one that bleeds money. The FIAT Kobelco K904C, K904CL, K904SS Parts Catalog is a 546-page binder that gives you the exact exploded views and OEM part numbers for every system on these machines. No aftermarket guesswork. No cross-referencing generic lists. Just the factory data from Kobelco.

546 Pages of Factory Part Numbers

Page counts tell you what you’re getting into. This catalog runs 546 pages front to back. Each section covers a specific subsystem from the weight assembly to the cab. You flip to the fuel tank section and find TANK ASSY. FUEL with numbered callouts for every clamp, fitting, and filter. Order a part by the number in the diagram, not by “looks about the same.” Industrial equipment tolerates zero slop. The catalog organizes everything by machine serial number range, so you know exactly which revision fits your K904C, K904CL, or K904SS. Check the application table on page 2 to match your unit’s serial prefix.

Fuel Tank Assy: Getting the Right Tank

Fuel system parts get swapped wrong more often than anything else on backhoes. A tank from a K904CL with a different serial range might have a different vent line or return fitting. The catalog shows the TANK ASSY. FUEL assembly with the original Kobelco part numbers, so you don’t order a tank that doesn’t bolt in. Same applies to the hydraulic lift tank (TANK ASSY. HYDR.) — those two tanks look almost identical, but the baffles and ports differ. Use the manual, not your memory.

Does This Catalog Cover Your Serial Number?

The first pages contain an application chart that lists every serial number range this catalog applies to. For example, K904CL units starting at 83010, K904C at 83100, and K904SS at 83070. If your machine’s serial falls outside those bands, you need a different revision. The catalog also covers K904D variants, but the focus is on the C, CL, and SS models. Cross-check your tag before you buy. There’s a table on page 3 that breaks out the production date codes — August 1983 (83.5) and later. Not every part interchanges across all years.

Contents: From Weight to Cab Assy

The table of contents lists these main sections: WEIGHT, FRAME ASSY, TANK ASSY. FUEL, TANK ASSY. HYDR., REDUCTION UNIT, CAB ASSY, DOOR ASSY., and FRAME ASSY (JAPAN). Each section has its own sub-numbering, like 011-1, 012-6A, 051-1A. That numbering ties back to the parts index. If you need a reduction unit seal, look under REDUCTION UNIT and find the right bearing or gasket listed with its size. The manual also includes assy-level part numbers for ordering complete assemblies when you don’t have time to piece things together. Check the related manuals for other Kobelco models: FIAT Kobelco ED150, ED150-IE 2013 Parts Catalog OEM and FIAT Kobelco ED150, ED150-2 2009 Parts Catalog OEM Manual cover different loader families.

Why Factory Parts Documentation Matters

Aftermarket parts catalogs renumber parts or skip the revisions. This is a scanned copy of the original Kobelco publication — Japanese and English text side by side. The exploded views are photographic quality line drawings with dimensions in millimetres. When the manual says “FRAME ASSY (JAPAN)” it distinguishes between frames built in Japan versus other plants. You can’t get that from a third-party summary. For more context on why factory specs matter, see the Automotive Industry Overview or read up on the Internal Combustion Engine to understand basic principles behind the systems you’re repairing. If you need more Kobelco coverage, FIAT Kobelco LK650-II 1992 Parts Catalog – OEM Factory Specs is another option.

How do I find the right part number for my K904SS fuel tank?

Flip to the TANK ASSY. FUEL section. Match your serial number range from the application table (page 2) to the correct illustration. The part number appears next to the callout.

Does this catalog include hydraulic pump breakdowns?

It covers the hydraulic lift tank (TANK ASSY. HYDR.) and reduction unit. For pump internals like pistons or swash plates, you need the service manual — this is a parts catalog only. It gives you the assembly-level numbers for the pump group, not individual components inside it.

You need part numbers that match the machine on your lift. Don’t waste time phoning dealers with “I need a tank for a K904C.” Open the catalog, find the illustration, order the exact assembly. That’s how you keep the job moving. Access the Factory Manual now.
