Using Komatsu WA320-5 Wheel Loader Parts Catalog
This Komatsu WA320-5 wheel loader parts catalog helps you locate aftermarket replacement parts by machine system and assembly. Its current coverage contains 867 assembly listings across 36 source sections. The navigation groups related sections for easier browsing; available choices include Engine, Hydraulic System, Work Equipment, Transmission and Electrical System.
Choose the section relevant to your repair, then compare the full Komatsu WA320-5 model designation, machine serial range and any engine or attachment information on the assembly page. Model suffixes, serial breaks and configuration notes remain important even where two diagrams look similar.
The published engine listings identify SAA6D102E-2L-8 (engine serial 26274903-UP). These are catalog applications, not a claim that every machine in this model series uses the same engine configuration.
Use the part-number links to inspect listed store products, or select the required parts and quantities to prepare a quote. Only the published sections are shown here; the catalog does not imply that every original book section or machine configuration is available.
Komatsu WA320-5 dimensions and transport reference

| B | Width over tires | Outside tire-to-tire width. Bucket width may be greater. |

| D | Wheelbase | Distance between the front and rear axle centers. |
Illustration is schematic and not to scale. Confirm actual machine dimensions, attachments and transport position before arranging haulage. Operating weight and shipping weight are different measurements; neither is established by this diagram.
