A final drive or swing drive assembly can be of two types: plug-in motor and gearbox, or totally integrated units. The design of your drive will dictate what options are available. The approaches adopted by final drive motor manufacturers and swing drive manufacturers are outlined below.
The model, serial and part number information can be found on the product plate; some examples are shown here. If it is missing or damaged, you may recognise your drive from the photos shown below or this excavator final drive diagram. This will help your FDC Partner identify the correct replacement options.
