An undercarriage assembly (20) for a work vehicle (10) includes first and second roller frame assemblies (22, 24), one on each side of the vehicle (10), an idler wheel assembly (28, 30) connected to one end of each roller frame assembly (22,24), and a drive wheel (32,34) connected to the opposite end of each roller frame assembly (22, 24). An endless elastomeric track belt (39) encircles a respective drive wheel (32, 34), roller frame assembly (22, 24), and idler wheel assembly (28, 30) on each side of the vehicle (10). A rigid support beam (26) connects each roller frame assembly (22, 24) to the main frame (12) of the vehicle (10). Each idler wheel assembly (28, 30) includes first and second self-aligning mechanisms (72, 90) to provide that the track belt (39) runs true and straight. The roller frame assemblies (22, 24) can be spaced laterally from the vehicle (10), using various size spacers, to provide various gage settings of the endless track belt (39). During adjustment of the roller frame assemblies (22, 24), a supporting arrangement (142) supports one track roller assembly (22) by the other track roller assembly (24).
