FIAT Kobelco K905, K905LC 1987 Parts Catalog

If you are ordering parts for a FIAT Kobelco K905, K905LC 1987 Parts Catalog machine and you have ever received the wrong counterweight bracket or fuel tank gasket because you guessed the part number, you know exactly why this document exists. The 544 pages in this OEM manual are not a reprint of some third-party compilation. This is the factory-issued parts list from Kobelco Construction Machinery America, printed in Japan in April 1987. It applies to K905 serial numbers LP-0601 onward and K905LC serial numbers YP-0115 onward, with LP-0901–1376 also covered. Page 1 shows the book code and serial number blanks – you fill those in before you order anything.

What the Fuel System Sections Cover

You need to find a fuel pump seal or a tank mounting bracket. The manual has three separate fuel-related sections: TANK ASSY. FUEL 041-01, TANK ASSY. FUEL 042-35, and PUMP ASSY. FUEL 043-28. That is not a typo – the 1987 K905 had different tank configurations depending on the customer specification. The table on page 4 (the “SPECIFICATION BY CUSTOMERS” matrix) tells you which assembly section matches your machine. Without that table you would be flipping through pages guessing which fuel tank diagram belongs to your serial number.

Counter-Weight and Frame: Four Variations

The UPP FRAME ASSY (011-01 and 011-03) and COUNTER-WEIGHT ASSY sections (012-01, 012-03, 012-20, 014-01, 014-03) show that Kobelco built these backhoes with at least four counterweight options – standard, silence, gain, and gain-for-silence. If you order a counterweight bracket without checking the “FOR SILENCE” or “GAIN” suffix on your machine, you are going to get a part that does not fit. This manual lists every part number and quantity for each variation. Page 4 includes the legend for standard versus optional application marks (filled circle vs. open circle). That level of detail is why you pay for the factory book.

Does This Catalog Cover Your Specific Serial Number Range?

Yes, if you have a K905 with serial LP-0601 or later, or a K905LC with YP-0115 or later. The book also covers K905 units LP-0901 through LP-1376. If your machine falls outside those ranges, you need a different manual. The front page tells you exactly which serial numbers apply – no guesswork.

Cab and Guard Group – More Than Just Glass

The CAB & GUARD GROUP (sections 051-01 through 052-35) includes installation instructions (INSTAL. CAB) and complete CAB ASSY breakdowns for three different cab configurations. If you need a rear-view mirror part, look at BACK-MIRROR 016-35. That section is a single page with the mirror bracket and mounting screws. The manual does not waste space – every page is a specific assembly with item numbers, part numbers, descriptions, and quantities. For the hydraulic tank, see HYDR TANK ASSY. HYDR 031-01.

3 Reasons to Choose OEM Documentation

First, the part numbers in this catalog are the same numbers Kobelco dealers use when you call them. Second, the exploded drawings show exactly which fastener goes where – a capscrew M10x1.5 is not interchangeable with a fine-thread capscrew. Third, the manual includes a parts type explanation (部品型録の見方) on page 5 that teaches you how to read the item-numbering system: the top-level assembly has no item number, its sub-components are item 1, 2, 3, and if a component is itself an assembly, it gets sub-numbers like 1-1, 1-2. That keeps you from ordering a sub-assembly when you only need a seal.

Page 1 lists the serial number ranges. That is all the introduction you need.

If you work on heavy equipment, you know that aftermarket parts catalogs often swap illustrations or omit the “FOR SILENCE” variants. The Automotive Industry Overview on Wikipedia notes that OEM documentation reduces liability and warranty claims – same principle applies here. Another perspective on parts traceability is available from the Automotive Industry Overview.

Can I use this catalog for the K905LC with serial YP-0115?

Yes, that serial range is covered.

What if I need a part number for the counter-weight assembly but my machine has a “SILENCE” option?

Go to the COUNTER-WEIGHT ASSY sections. Look for the ones marked “FOR SILENCE” – that means 012-03 and 014-03. Page 4 has the specification combination table. Cross-reference your machine’s customer spec (usually stamped on the frame tag) with the table to find the exact page number. Without that step you might order a standard counterweight that does not clear the silencer enclosure. The manual lists every bolt and washer for each variant, so take the time to read the table.

Owning this FIAT Kobelco K905, K905LC 1987 Parts Catalog means you stop wasting money on parts that do not fit. The exploded views, genuine part numbers, and serial-number-specific coverage give you the same information the dealership uses. Get the manual on your bench or tablet before you open the parts box. Access the Factory Manual from AutoRepairManuals and keep your backhoe running on the right hardware.
