Komatsu Hanomag WA75-3, WA85-3 Parts Catalog

Komatsu Hanomag WA75-3, WA85-3 Parts Catalog is what you need if you’re rebuilding or repairing these loaders. Without it, you’re guessing on part numbers – and that costs time and money. This factory book has 232 pages of exploded views and genuine Komatsu Hanomag part numbers. Every nut, seal, gasket, and pump assembly is listed with its exact OEM number. I’ve been an ASE Master Tech for 28 years, and I can tell you that the difference between a correct part and a close one is usually a single letter suffix. This catalog gives you that letter.

232 Pages of Factory Parts Data

Every section in this catalog is organized by assembly. You get exploded diagrams with reference numbers, then a table listing part number, description, and quantity. For example, Section 02 covers the cylinder block and attaching parts. You’ll find the block itself, oil cooler, water pipe, and all bolts. The quantity column uses an ‘X’ to indicate “as required” – meaning you order based on inspection. That’s factory logic, not aftermarket guesswork.

Cylinder Block and Attaching Parts – Section 02

This section is critical if you’re tearing down the bottom end. It includes the cylinder block, main bearing caps, connecting rods, and the front plate. The diagrams show exactly how everything fits. You’ll see the difference between the WA75-3 and WA85-3 blocks – there are part number variants. The catalog includes the engine mounting assembly too, in Section 01. Don’t skip Section 00 – that’s the maintenance kit, which includes the parts you’ll need for a complete overhaul. For related loader parts, check the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide if you’re working on older tractors.

What Does the Fuel System Section Cover?

Sections 20 through 29 cover everything from the injection pump body to the fuel filters. You get the injection pump regulator (Section 25), the fuel pump (Section 26), and pre-filter and fine filter sections (28 and 29). Each part has a clear illustration. If you’re replacing the injection pump, Section 24 breaks down the pump body and its internal components. The fine filter section (29) lists the element part number – a common item that gets confused with aftermarket ones. The Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs covers similar fuel system components for another brand.

Match Your Chassis Number First

Before you order any part, check your loader’s chassis number. The catalog covers WA75-3 from chassis HA950051 onward, and WA85-3 from HA960051 onward. If your machine is earlier, the part numbers may differ. Each section notes any chassis-specific changes. For example, the general information page (page 3 of the original book) shows how part numbers change with suffix letters A through E. That’s not decoration – it’s the difference between a part that bolts on and one that doesn’t.

Source Authenticity: Why OEM Matters

This is an original factory PDF – not a third-party compilation. The part numbers are Komatsu Hanomag numbers, directly from the manufacturer. I’ve seen too many aftermarket parts catalogs that substitute numbers or use cross-references that are wrong. This one is the actual parts book used by dealers. The page numbers and indexes match the printed version. If you want to know how the automotive industry standardizes part numbering, refer to the Automotive Industry Overview for context. The same logic applies here – consistency is key. Additionally, the Automotive Industry Overview explains why OEM data is critical for interchangeability.

Who Needs This Catalog?

If you maintain a Komatsu Hanomag WA75-3 or WA85-3 for a living, or even if you’re a farmer doing your own repairs, this catalog saves you from ordering the wrong part. It’s also useful for shops that service multiple loader models. The exploded diagrams help you identify what’s missing or broken. That alone is worth the price of admission.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog. It lists part numbers and quantities only. For torque specs, you need the service manual.

How do I find the right part for my loader?

First, locate your chassis number. The catalog covers WA75-3 from chassis HA950051 and WA85-3 from HA960051. Each section starts with an exploded view. Find your assembly, note the reference number, then cross-reference to the table. Pay attention to the suffix letters A through E – they indicate different part variants. For example, the brake valve housing in the general information shows five different part numbers for suffixes A to E. One wrong letter and the part won’t fit. Always confirm the suffix from your existing part.
