The undercarriage of the machine is not suspended. Pivot shafts (Figure 2, Item 5) connect the roller frames at the
rear of the machine.
The equalizer bar connects the two roller frames at the front of the tractor. The equalizer bar keeps the roller
frames in a constant position relative to the main frame and to each other.
The track roller frames consist of front frame (Figure 2, Item 2) and rear frame (Figure 2, Item 3). The front idler
(Figure 2, Item 1) is installed on the front frame. The rear idler (Figure 2, Item 6) and track rollers (Figure 2, Item 4)
are installed on the rear frame.
The tracks (Figure 2, Item 7) are sealed and lubricated for increased wear resistance.
A recoil mechanism is installed in the roller frame in order to keep the track adjusted.
The standard undercarriage on each side of the machine has seven track rollers. Four of the rollers are single-
flange track rollers and three of the rollers are double-flange track rollers.
The installation of the track rollers is arranged from the front of the machine in the following order:
