This wheel loader application is listed for machine serial WA320H20051-20560; the diagram and parts table retain the selected configuration and its source notes.

Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
When selecting transmission or torque-converter parts, compare the assembly description, machine serial break and any configuration notes. Similar-looking diagrams can cover different internal parts and should not be treated as interchangeable.
