FIAT Kobelco K907D, K907DLC 1986 Parts Catalog

You’re halfway through a pin replacement on a K907D, and the bushing kit you ordered doesn’t match. The aftermarket catalogue had a different part number for the same illustration. Now the machine sits, the customer waits, and your profit on the job is gone. I’ve seen that happen enough times to tell you flat: if you’re working on a FIAT Kobelco K907D, K907DLC 1986 Parts Catalog machine, you need the factory book. Not a third-party compilation. Not a scanned copy of a copy. The 472-page OEM manual that Kobelco printed in Japan in 1986. That’s the only one that has the correct part numbers, serial number breaks, and group codes for ordering.

This is a parts catalog, not a service manual. That means exploded-view diagrams, item numbers, and part numbers for every assembly on the machine — upper frame, counterweight, reduction unit, hyd tank, fuel tank, cab, guard, and more. If you’re trying to identify a seal, hose, or bracket and your current source keeps giving you wrong numbers, this book fixes that.

Upper Frame Assy & Counter-Weight Assy: Exploded Views

Page 4 of the catalog shows the upper frame assembly and counter-weight group broken into separate spec codes: standard, silence, gain, and gain for silence. Each variant has its own exploded diagram and parts list. The UPP FRAME ASSY section starts at page 011-01; the COUNTER-WEIGHT ASSY groups cover pages 012-01 through 014-03. If your machine has the optional silence package, you order from a different column than a standard machine. This catalog tells you exactly which column to use because it lists the “combination code” (組合せ符号) — standard gets one diagram, option gets another. Without that, you’re guessing. Guessing costs you return shipping and down time.

7 Systems Grouped by Assembly

The catalog organizes parts into two major groups: the upper group (アッパグループ) and the cab & guard group (キャブオヨビガードグループ). Under the upper group you’ll find:

• UPP FRAME ASSY (standard, silence)
• COUNTER-WEIGHT ASSY (standard, silence, gain)
• REDUCTION UNIT
• BACK-MIRROR
• TANK ASSY, HYDR, FUEL
• PUMP ASSY, FUEL
• FILTER ASSY

Each assembly has its own page range, and the table of contents on page 3 (printed in English and Japanese) tells you exactly where to flip. For the cab & guard group, you get INSTAL CAB variants (051-01, 051-28, 051-46) and CAB ASSY variants (052-01, 052-28, 052-35). If you need a door seal or window gasket, you need the right cab sub-variant. This catalog gives you the part number for each.

Does This Manual Show Hardware Torque Specs?

No. This is a parts catalog, not a service manual. It does not list torque values, fluid capacities, or repair procedures. If you need torque specs for the reduction unit bolts or the hydraulic tank mounting, you want the separate service manual. But if you need the correct part number for a specific capscrew — say a Z513016050 cap screw — you’ll find it here. The catalog lists each hardware item with its part number, description (in Japanese and English), and quantity per assembly. For example, on page 4 you’ll see cap screws and sem s-bolts with their sizes. That’s critical if you’re ordering bolts from a dealer and they ask for the part number rather than a grade and thread pitch.

How the Parts Catalog Is Organized (And Why It Works)

Kobelco uses a combination code system. Each assembly page starts with a group number (like 011-01), and the item numbers correspond to the exploded diagram. The part number, description, remarks, and quantity are listed in columns. The first line of each table shows the sub-assembly itself without an item number; then individual components are numbered 1, 2, 3… The catalog includes both standard and option codes, so you have to match your machine’s serial number to the right column. Page 3 even has a blank space for you to write your machine serial number (機械番号) and engine serial number (エンジン番号) — I’ve seen shops skip that and then order parts for the wrong build. Don’t be that shop.

Source Authenticity: OEM Kobelco Japan, Not a Reprint

The front matter states: “Printed in Japan. 1986.12” and includes a copyright by Kobelco Construction Machinery America, LLC. This is not a third-party scan that lost resolution on the diagrams. This is the original factory file, 472 pages, with all the line-art clarity you need to read the part numbers. When you access this from AutoRepairManuals, you’re getting the exact same book a dealer would pull up on their internal system — because the dealer’s parts database is built from these same page layouts. I’ve compared aftermarket parts catalogues to OEM ones like this, and the aftermarket ones often swap part numbers for similar-looking items. On a machine that uses different hyd tank mounts depending on whether it has a knob or a latch (TANK ASSY HYDR vs FUEL), that mistake means the bracket won’t bolt up.

FAQ

Will this catalog work for a K907DLC with serial number YG-0501?

Yes. The cover explicitly lists K907DLC YG-0501~ as applicable.

How do I know which assembly page to use when there are multiple codes for the same assembly — for example, CAB ASSY 052-01 vs 052-28 vs 052-35?

Use the specification combination table in the front of the catalog (page 4 shows an example). Match your machine’s serial number and any option codes (like “SILENCE” or “GAIN”) to the correct code. For instance, if your cab is the standard spec, use page 052-01; if it has the silence package, use 052-28; if it’s a different customer spec, use 052-35. The column headers in the table of contents indicate which code applies to which serial number range. If you’re unsure, call your dealer and read the machine serial number — they’ll verify the spec using the same system this catalog is built on.
