Front Idler D155-5

Prdocut introductino:

A tracked vehicle uses a combination of wheels and rollers, including drive sprockets, idler wheels, track return rollers and road wheels. It is quite similar in concept to a conveyor belt, only instead of a machine carrying objects on top of a powered continuous belt, it's a machine that moves itself over a continuous belt. In a typical application, power is transmitted to a drive sprocket (or drive wheel), which drives the track around its loop. On the opposite end of the vehicle, there is an idler wheel, which provides a pulley wheel  of sorts. On some applications, the drive sprocket and idler wheel carry some of the weight of the vehicle, for the purposes of this description, we will assume the drive sprocket and idler wheel are not weight-bearing units, and the drive sprocket is on the front . Since the drive sprocket can be at either the front or the rear of the vehicle depending on the design, the idler wheel either carries the track back off the ground and returns it to the drive sprocket (rear idler wheel), or receives track from the drive sprocket and lays it down in front of the road wheels (front idler wheel). The idler wheel is not powered, just like an idler gear.
