Komatsu Gold Book Parts Catalog

You’ve been burned by a wrong part before. Every tech has. You order a gasket kit, it shows up with the wrong bore, or the filter threads don’t match. That’s time lost, money wasted, and a machine sitting. The Komatsu Gold Book Parts Catalog kills that problem. It’s the factory listing – 154 pages of genuine Komatsu part numbers, organized by system. Filters, ground engaging tools, undercarriage, repair items, hardware, engine parts, seals, electrical, safety, meters, brakes, V-belts. Everything you need to order the right piece the first time.

Filters and the Cost of Cheap Replacements

The catalog opens with filters – and it doesn’t just list part numbers. It explains failures due to insufficient filter maintenance and compares genuine parts to imitation parts. You want to see what happens when you run a cheap filter? Page 6 shows you the debris trail. The hybrid hydraulic filters section (page 12) is worth reading if you’re dealing with a machine that sees hard use. The table of filters (page 16) gives you the exact part number for every oil, fuel, air, and hydraulic filter across dozens of Komatsu models. No cross-referencing from a third-party book that guesses. This is OEM data.

Ground Engaging Tools: Cutting Edges, Bucket Teeth, Ripper Points

If you’re replacing a cutting edge or a set of bucket teeth, you need the correct dimensions and hardness spec. The Ground Engaging Tools section (starting page 22) covers cutting edges, end bits, side corners, bucket teeth, ripper points, blade reinforcement plates, shear pins, hinge pins, and the KVX TOOTH SYSTEM. Each listing includes the part number and application. No guessing which tooth fits your bucket. The drawings are legible, the part numbers are direct. You can verify against the machine serial number using the table.

Why Genuine Komatsu Undercarriage Parts Matter

Undercarriage is where you really feel the difference between OEM and aftermarket. The catalog includes a track shoe selection guide and a full table of undercarriage parts (page 59). The KUC REPORTING PROGRAM – Version 1 (page 80) is a tool for tracking wear. If you’ve ever had a rail crack at 2,000 hours because you used a non-OEM link, you know why this matters. The catalog shows you the exact part numbers for shoes, rollers, idlers, sprockets, and chains. The track shoe selection table (page 57) helps you pick the right shoe width and type for your ground conditions. You can cross-reference with this Wikipedia article on diesel engines to understand how undercarriage load affects engine life, but the catalog itself is all you need to order.

7 Systems Covered in 154 Pages

Here’s what the catalog covers beyond the big sections: Repair and Maintenance Items (sealant kits, liquid gaskets, thread tighteners, moly lubricant – page 81), Tools (power wrenches, torque wrenches, digital multimeters, compression gauge kits – page 101), Hardware (bolts, nuts, nut and bolt kits), Engine Maintenance Parts (gasket kits, short blocks, pistons, rings, bearings, thermostats, fuel water separators – page 115), Reman, Seals and Hoses (hydraulic cylinder seal kits, O-rings, oil seals, hose clamps, low-pressure hoses, hydraulic hoses – page 124), Electrical Parts (batteries, wires, switches, lights, fuses, starting switches – page 135), Safety and Efficiency Items (beacons, alarms, mirrors, seat belts, vandalism locks – page 144), Meters and Gauges (monitor panels, temp gauges, speedometers, service meters – page 148), Brakes (bands, linings, discs, pads – page 151), and V-belts. That’s 154 pages of factory data. You can look up a hydraulic hose by its Parker part number if you need to source locally, but the catalog gives you the Komatsu part number to order genuine.

Get the Right Part Number Before You Order

You’ve got a machine down. You need a piston ring set, a brake pad kit, or a fuel spill hose. Open the catalog. Find the section. Look up the model. Write down the part number. That’s it. No guessing, no cross-referencing aftermarket charts that are wrong. This catalog is the same one the dealer uses. It’s a PDF, so you can search it by keyword on your phone or tablet. The Tools section (page 101) lists torque wrenches and power wrenches – but you’re not buying tools from this catalog, you’re buying parts. The catalog is a parts reference, not a service manual. If you need the service spec for tightening that head bolt, you need the service manual – but this catalog gives you the part number for the gasket kit and the seal kit.

If you work on multiple Komatsu models, pair this catalog with FAI 67-80DT Hydraulic Steering Piston Parts List or Komatsu WH609-1 WH613-1 Parts Catalog | 347 Pages OEM. For small excavators, Komatsu PC14R Parts Catalog – Order Correct Parts Fast is a good companion. The Gold Book covers the full range of parts and accessories – it’s a general reference. For a specific machine, you’ll want the model-specific parts catalog. But for stocking shelves, ordering common wear items, and understanding what fits what, this is the book.

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog – it lists part numbers, not tightening sequences. You need the service manual for torque values.

How do I use the catalog to order a gasket kit for a Komatsu engine?

Go to the Engine Maintenance Parts section (page 115). Find the Gasket KIT subsection. Look up your engine model number. The catalog lists the part number for the complete gasket set. Write it down, order from your dealer. If you cannot find your engine model, the catalog includes a table of short blocks (page 116) – you can cross-reference the block part number to narrow down the gasket kit. The key is to use the exact model designation from the machine’s serial number plate. Do not guess based on displacement alone; the catalog has multiple entries for similar engines. Call your dealer if you have two possible part numbers – they can check fitment against the serial number. The catalog also includes a comparison of genuine parts and imitation parts (page 10) that explains why the genuine gasket can handle higher clamping loads. That’s worth reading before you order a cheap aftermarket set.

You’re tired of returns. You’re tired of waiting for the wrong part. Access the Factory Manual and get the correct part number every time.
