An idler assembly 20 for a track roller frame 18 comprises a housing 32 having a central cavity 38 that is connectable to an end of frame 18. Cavity 38 houses a yoke 34 having spaced apart arms 60, 62, with an idler wheel 21 rotatably supported between arms 60, 62, and yoke 34 also connects to a longitudinal piston 68 in frame 18. A key (36, Figure 4) couples yoke 34 to housing so the yoke is movable relative to the housing; preferably the key slides in a longitudinal slot 72 in an arm 60, 62. The key may have a flange (84, Figure 4) having contact surfaces (90, 92, Figure 5) parallel to, and offset at differing distances from, a central plane X, which may allow the key to fit in an aperture 64 in two specific orientations while preventing further movement. Yoke 34 may be adjustable both vertically and horizontally.
