Track Roller
0009
Seven double flange track rollers fasten to each track roller frame. The track rollers contact the inside surfaces of
the track links. The inside surfaces of the track links equally distribute the weight of the machine over the track.
Flanges (Figure 2, Item 3) prevent the track from moving side to side. Collars (Figure 2, Item 2) receive the side
load on the roller. Inside the center of the shaft (Figure 2, Item 1) is an oil reservoir. The oil in the reservoir
lubricates the bearing surfaces. Duo-Cone seals (Figure 2, Item 4) install on both ends of shaft.

Track Carrier Roller
0009
The track carrier roller supports the track between the front idler and the sprocket. A roller support bracket fastens
to the track roller frame. A clamp holds the shaft (Figure 3, Item 1) in the roller support bracket. Movement of the
shaft inside the roller support bracket aligns the track carrier roller with the front idler and the sprocket. The roller
(Figure 3, Item 5) turns on two tapered roller bearings (Figure 3, Item 3).
The track carrier roller consists of the shaft (Figure 3, Item 1), Duo-Cone seal kit (Figure 3, Item 2), tapered roller
bearings (Figure 3, Item 3), cover (Figure 3, Item 4), roller assembly (Figure 3, Item 5), and collar assembly (Figure
3, Item 6).
