A track roller assembly is secured between spaced roller mounting members. The track roller assembly includes a shaft having a head and an end both of which are hexagonal and are received in hexagonal openings of outer and inner ring members secured to the mounting members. The opening receiving the head is provided with diametrically-opposed semi-circular threaded apertures. The head of the shaft is also provided with diametrically-opposed semi-circular threaded apertures which are alignable with the apertures in the hexagonal opening. Fasteners are then threaded into the aligned apertures to hold the shaft in position between the mounting members. A bearing circumscribes the shaft and is bolted at one end to the outer ring member. A roller is mounted on the bearing.
