Abstract: A tray is provided for orienting and conveying items having a longitudinal axis, a tip, an opposite head, and a head-up and a head-down orientation, the tray conveying the items in a direction of travel and including a series of connected, function-oriented static regions configured for orienting the item from a random orientation to a desired tip-down orientation, at least one of the regions being inclined for facilitating movement of the item through the regions, the regions being configured such that proper orientation of the item is achieved without operator contact.

Abstract: A lash adjuster is retained in unit assembly in a stepped socket of a valve actuator member by means of a normal flat retainer ring, preferably of compliant plastic, that is operatively positioned in an annular groove in the outer peripheral surface of the cylindrical body of the adjuster, the groove being defined by spaced apart sidewalls and an interconnecting base wall, one of the walls being at right angles to the axis of the body and the other wall being inclined at an acute angle to right angle wall whereby during insertion of the lash adjuster into operative position within the socket, the retainer ring can be forced toward the other wall so as to be temporarily deformed into a frustoconical configuration.

Abstract: A rocker arm assembly for use in the valve train of an internal combustion engine of the type having a fixed rocker shaft for supporting at least one rocker arm and having an axial passage adapted to be in continuous communication with the pressurized lubricant supply of the engine and with at least one radial riser passage extending from the axial passage; the rocker arm assembly including a rocker arm having a hydraulic lash adjuster operatively positioned in a socket provided in an arm thereof and, a hybrid bearing operatively positioned in the rocker arm so as to encircle the rocker shaft over the oil riser passage.

Abstract: A guide (28) is provided for retrofitting an existing internal combustion engine block (10) with roller cam followers (24 and 26) in place of conventional barrel-type lifters, without modification of the block itself. The guide includes a guide bar (64), keyed to the upper body (38) of each follower to allow limited rotational freedom thereof and a resilient C-shaped spring clip (70) which simultaneously bears downwardly on the upper surface of the guide bar and upwardly on the lower surface (40) of an engine block boss (18) defining follower receiving bores (20 and 22). Annular spacers (72) are provided, if required, to displace the guide bar upwardly from the upper surface (52) of the boss. An upper leg (76) of the spring clip wraps around the guide bar for retention therewith and a lower leg (78) of the spring clip is necked at a point (86) intermediate adjacent cylindrical portions (30 and 32) of the follower boss for retention therebetween.
