A lubrication system is provided for use with a bearing including an outer race, an inner race, and bearing elements disposed therebetween. Rotation of the bearing and a shaft journaled thereby induces air movement having a first air velocity and a path adjacent the bearing. The lubrication system includes a structure providing a passageway through which a lubricant entrained in gas is delivered at a second velocity to the bearing. The lubrication system further includes a flow modifier disposed relative to the bearing and the structure to modify the first air velocity to promote movement of the lubricant into the bearing.

The rigging side frame of claim 16 wherein said frame structure includes pin holes near the front corners thereof for pinning the cam plate link in its stowed position and for pinning a deployed cam plate link of one rigging side frame to the cam plate attachment structure of the frame structure of another rigging side frame. 18. The rigging side frame of claim 17 further comprising a cam plate link quick release pin for pinning the cam plate link in its stowed position within the frame structure when stowed and to the frame structure of an adjacent riggi
