A bearing support member, mountable about a support stud, has two support arms extending toward side walls of a rocker arm. A bearing cup is rigidly mounted on each respective side wall and extends over the respective arm of the bearing support member, providing an annulus. Rolling members within the annulus permit the rocker arm to freely oscillate rotatably while being constrained axially. The bearing cups may include a keyed shape to limit orientation of the bearing support member. Another aspect of the invention is a rocker arm subassembly having 'open' bearing cups.

Rocker arm assembly

A bearing support member and bearings form a subassembly that can be inserted, in the direction of the axis of the bearings, into a bore of a rocker arm. A support stud can then be passed through an aperture in the rocker arm and a bore in the bearing support member so as to engage the rocker arm and maintain alignment of the rocker arm and bearings. Also disclosed are an inner sleeve and particular configuration of the bearing support member to facilitate manufacture of the bearing support member by powdered metal forming.

A device to determine rotational parameters of a rotatable shaft mounted within a stationary tube comprising a substantially annular shaped target. The target is attached to a rotatable shaft. A target retainer has a bore for receiving the rotatable shaft, and is dimensioned to be securely attached to an interior surface of the tube. The target retainer has a radially extending surface adjacent each axial end of the target to restrain axial movement of the target, and also has an aperture adjacent the outer periphery of the target. A sensor extends into the aperture when the sensor is mounted on the stationary tube. Fasteners connect the sensor to the stationary tube.
