A hinge assembly for an articulated vehicle (10) having front and near frame portions (12, 14) joined at a pair of vertically aligned hinges (18, 20). Each hinge includes a similar roller bearing assembly (48) attached to the front frame portion and having a rotatable protruding trunnion (52). The rear frame portion includes recesses (70) for receiving the trunnions and trunnion caps (74) for retaining the trunnions. The trunnion of each bearing assembly includes a shoulder pin (118) with a lust bearing cone (134) plead against the shoulder (126) and a second bearing cone (142) spaced apart from the first cone. A spacer ring (154) received on the pin is biased against the second cone by an end cap (160) secured to the end of the pin. A shim pack (158) between the end cap and the end of the pin limits the amount by which the space between the cones may be narrowed to limit and control the pre-load of the bearing assembly.
