ABSTRACT:
A bearing support member has two support arms extending in opposite directions along an axis and is adapted for mounting about a stud means. A bearing cup is fixed to the rocker arm, extending over each support arm. Rolling members are provided within an annulus formed between the support member and the bearing cups such that the rocker arm is free to oscillate rotatably with respect to the bearing support member. The bearing cups have a bottom surface forming an interference fit, axially, with an end surface of the bearing support member such that a preload is applied to the bearing support arm to reduce and control axial play. A protrusion and cutouts facilitating the preload and a method of assembly are also disclosed.
