Why This Parts Book Matters for Your WA350-3A

When you are repairing or servicing a Komatsu WA350-3A, using the wrong part number can mean delayed repairs, mismatched components, and unnecessary downtime. This parts book eliminates the guesswork. Every assembly is broken down into its individual components with clear exploded-view illustrations, so you can see exactly how parts fit together and which part number corresponds to your machine’s serial number range.

The manual covers all the major systems on the WA350-3A: the SA6D108E-2A-S7 engine, transmission with torque converter, hydraulic system, axles, electrical system, operator’s compartment, and work equipment. Whether you are replacing a single seal, rebuilding a cylinder, or ordering a complete assembly, the part number tables and illustrations in this book give you the reference you need.

The serial number breakdowns are particularly valuable. Komatsu made running changes throughout the WA350-3A production run, and this parts book identifies which parts apply to which serial number ranges. That means you can verify fitment before you order, avoiding the frustration of receiving a part that doesn’t match your machine.
