Using Komatsu WA320-3 Wheel Loader Parts Catalog
This Komatsu WA320-3 wheel loader parts catalog helps you locate aftermarket replacement parts by machine system and assembly. Its current coverage contains 949 assembly listings across 53 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 WA320-3 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 S6D108-1G-6 (engine serial 10001-UP) and SA6D102E-1B-7C (engine serial 26200163-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 WA320-3 dimensions and transport reference
Use the lettered diagram to identify measurements when comparing WA320-3 wheel loader specifications. This is a general measurement guide, not a dimensioned drawing of your machine.
| Reference | Measurement | Definition |
|---|---|---|
| A | Overall length with bucket | Rear-most to front-most point with the stated bucket and attachment position. |
| B | Width over tires | Outside tire-to-tire width. Bucket width may be greater. |
| C | Height to top of cab | Ground to cab roof. Beacons, exhausts or attachments may extend higher. |
| 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.
