What the Komatsu WA320-3MC Parts Book Gives You

This Komatsu WA320-3MC parts book is a complete illustrated parts catalog covering machines from serial number A31001 and up. Every major assembly on the wheel loader is broken down into exploded-view illustrations with itemized part numbers, so you can see exactly how components fit together and identify the correct part for your machine without guesswork. The catalog spans the full machine: engine, fuel system, cooling, electrical, transmission, torque converter, axles, hydraulics, steering, brakes, operator’s cab, air conditioning, hood and guards, wheels and tires, and the complete work equipment including boom, buckets, cylinders and cutting edges.

Each section lists part numbers alongside quantity references and descriptions, making this parts book a practical tool for anyone who needs to order replacement components, verify part compatibility, or understand how the WA320-3MC is assembled. Whether you are maintaining a fleet, repairing a specific failure, or restoring a machine, having the correct part number for your serial number range saves time and prevents ordering errors.

Why This Parts Book Matters for WA320-3MC Owners and Technicians

Komatsu wheel loaders are built to work, and keeping them working means having the right parts information at hand. The WA320-3MC is a versatile machine used in construction, aggregates, agriculture and material handling, and when a component fails, the difference between a quick repair and a long downtime often comes down to identifying the correct replacement part the first time. This parts book provides the exploded views and part numbers you need to do exactly that.

The catalog covers serial number A31001-Up, so you can be confident the part numbers shown match your machine. Sections are organized by assembly, mirroring how the machine is built, which makes it straightforward to navigate from a system down to the specific component. The hydraulic and transmission sections are particularly detailed, reflecting the complexity of the WA320-3MC’s drive and implement systems, and the electrical section includes harness routing and component locations for the E.C.S.S. system.
