Abstract: A final drive assembly for a machine includes an input shaft drivably coupled to a prime mover. The input shaft is coupled to and drives a first stage gear assembly. The first stage gear assembly further drives a second stage gear assembly. The first and second stage gear assemblies drive a ring gear which is coupled to a wheel of the machine. The first and second stage gear assemblies are disposed between a first bearing assembly and a second bearing assembly. A spring member preloads the first bearing assembly to limit an axial movement of the first and second stage gear assemblies.
