Final drive

(55) Final drive

The output flow from the rear pump flows through the swivel to the right travel motor. The output
flow from the front pump flows through the swivel to the left travel motor. The pump delivery flow
causes rotation of the travel motors. The torque of the travel motors is transmitted to the final drives.
The rotational speed of the travel motors is reduced by gear reduction in the final drive. The final
drive (55) increases the torque and the rotational force drives track (53) via sprocket (54).
