Output shaft (25) of travel motor (24) is splined to coupling (23). Coupling (23) is splined to sun gear (22) .The final drive consists of two groups. The first group consists of the three stages of the planetary gear reduction. The second group is the output group.
The first stage reduction group consists of the following components: sun gear (22), planetary gear (16), planetary carrier (19) and cover (15). The group for second stage reduction consists of the following components: sun gear (33), planetary gear (10), planetary carrier (13) and ring gear (31). The third stage reduction group consists of the following components: sun gear (32), planetary gear (8), planetary carrier (5) and ring gear (31) .
The output group is described in the following manner. The rotation of drive sprocket housing (2) drives the track. Drive sprocket housing (2) and ring gear (31) are connected by bolts (3). Cover (16) is bolted to ring gear (31). The drive sprocket housing, the ring gear and the cover are supported by roller bearing (28). This planetary assembly rotates with ring gear (31) .The planetary gears reduce the travel speed. The travel speed is reduced by the ratio of teeth of the sun gear and the ring gear. The compact final drive offers a greater reduction ratio when the sun gear is incorporated inside the ring gear.Operation
Sun gear (22) is splined to coupling (23). Output shaft (25) of travel motor (24) is splined to coupling (23). The rotation of output shaft (25) is transmitted to sun gear (22) by coupling (23). When sun gear (22) rotates clockwise, the final drive operates in the following manner.

First Stage Reduction Group (15) Cover. (16) Planetary gear (first stage). (17) Roller bearing (first stage). (19) Planetary carrier (first stage). (22) Sun gear (first stage). (34) Rotational direction (first stage reduction group).In the first stage reduction group, sun gear (22) causes planetary gears (16) to rotate counterclockwise. Planetary gears (16) mesh with sun gear (22) and cover (15). Planetary gears (16) rotate around sun gear (22) and the internal teeth of cover (15). Each planetary gear (16) is mounted to planetary carrier (19) by roller bearings (17) and retainer rings in order to form a planetary assembly. Planetary carrier (19) rotates in
