Abstract: A slinger for use between a housing and a rotatable member passing therethrough includes an engaging member for mounting on the rotatable member, a slinger portion extending radially outward from the engaging portion, and a sealing portion generally axially extending from the slinger portion wherein the sealing portion extends radially outward when subjected to centrifugal force caused by rotation of the rotatable member to form a secondary seal. The slinger may be formed of a translucent polymer to facilitate a visual inspection of a primary seal located behind the slinger.

Abstract: A steering knuckle assembly receives a distal end of a steer axle beam which is generally symmetrical about a center line and has a pin bore therethrough. This knuckle assembly includes a steering knuckle which pivotally cooperates with the axle beam distal end. The steering knuckle includes a pair of yokes where each has a yoke bore longitudinally therethrough coaxially aligned with each other and with the pin bore. Each yoke also includes a yoke outer surface, and a yoke face surface which cooperates with a corresponding axle beam distal end and has an aperture formed therein. The knuckle assembly also includes a kingpin which has opposed ends and is received by the pin and yoke bores. Also included is a pair of yoke seals, each received by the yoke face aperture which includes an annular housing and an annular rubber portion. The rubber portion has at least one lip which operatively contacts the kingpin to provide a seal therewith.

Abstract: A device is provided for actuating force-receiving members of a torque transmission apparatus. The force-receiving members engage first and second rotatable members. The device includes a body with a working face adapted to apply a force to the force-receiving members, wherein at least a portion of the working face includes an arcuate surface.
