Kobe Steel K904D, K904DL 1985 Parts Catalog

If you have ever ordered a replacement part for a Kobe Steel excavator and ended up with the wrong size or a different revision because the aftermarket book had a blurry drawing and no part number cross-reference, you know the frustration. This 570-page Kobe Steel K904D, K904DL 1985 Parts Catalog is the same binder the dealer parts counter uses. It is not a reprint from some third party that scanned a copy of a copy. It is the original Japanese factory print, shipped to dealers in 1985, with every part number tied to a specific machine serial range.

Upper Group and Frame Assembly: What the Manual Covers

Section 011-01 starts with the UPPER GROUP and IPP FRAME ASSY. That is the main structure that carries the boom, arm, and counter-weight. The catalog breaks it into two variants: standard frame and a frame marked FOR SILENCE. You will also find the silent version cross-referenced at page 011-03. If you need a replacement part for the upper frame on a K904D with serial LW-5801 or later, the part number here is the one you want. The book also includes the BACK-MIRROR and REJECTION UNIT under the same upper-group heading.

Fuel System Parts Breakdown

Working with hydraulic tanks and fuel tanks? The catalog lists TANK ASSY, FUEL at page 041-01 and TANK ASSY, FUEL (a second variant) at 042-35. Then comes PUMP ASSY, FUEL at 043-24 and FILTER ASSY at 045-20. That is the entire fuel circuit from tank to filter – one section, no hunting through separate volumes. The hydraulic tank assembly (TANK ASSY, HYIЖ) is also in the same pages, so you can order the correct fuel and hydraulic tanks in one pass.

Why You Need 570 Pages of Part Numbers

Aftermarket parts catalogs for these older Kobe Steel machines often skip the minor revisions. This one covers machine serial numbers K904D LW-5801~ and K904DL LX-1201~. It also includes specification variations for different customers – the table of contents lists SPECIFICATION BY CUSTOMERS. That means if your machine came from a specific fleet order, the part number you need may be unique. 570 pages are there so you don’t guess. You open to the right assembly group, find your machine serial range, and order the part number printed in the book.

Check the Counter-Weight Assembly Before Ordering

Counter-weight assemblies have four separate listings: standard (012-01), silence version (012-03), an extra standard listing at 012-20, and a “GAIN” version (014-01) with its own silence variant (014-03). If you order the wrong counter-weight, the machine will not balance correctly – and you will spend a shift returning parts. The catalog separates them clearly, with part numbers tied to each sub-model.

Cab & Guard Group: Installation and Assembly

Sections 051-01 through 052-35 cover the INSTAL. CAB, CAR ASSY, and CAN ASSY. If you need a cab guard, door latch, or the entire cab assembly for a K904D or K904DL, you will find the exploded view here. The page numbers run from 051-01 to 052-35, so you can flip directly to the cab group without thumbing through the whole book.

3 Reasons to Use OEM Documentation Instead of Aftermarket

First, the pricing is set by factory list – no markups for “reproduction rights.” Second, the drawings are clean and the part numbers are printed in the same font the Japanese engineers used. Third, you avoid the risk of a mis-scanned number that sends you a part that does not fit. For other Kobe Steel machines, check the Kobe Steel MD180 Parts Catalog and the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide if you work on older ag equipment. For wear parts on compact excavators, see the Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs.

Frequently Asked Questions

Does this parts catalog include engine parts?

No. The manual explicitly states engine parts are in a separate engine parts catalog. This book covers everything else: upper frame, counter-weights, fuel system, cab, and hydraulic tank.

What machine serial numbers are covered?

K904D serial LW-5801 and later, K904DL serial LX-1201 and later. If your machine falls outside those ranges, you will need a different edition. The manual includes a space on page 3 to write your machine serial number for quick reference.

That is the kind of detail a 570-page factory catalog gives you. Access the Factory Manual and keep it on your tablet or print the pages you need for the job. No guessing, no wasted trips to the dealer with the wrong part number.
