ABSTRACT:
The system includes a spindle having a threaded end and a lubricated area spaced from the threaded end, the spindle having a longitudinal axial lubricant passageway extending from the spindle end and terminating adjacent the lubricated area. A lateral lubricant passageway communicates the longitudinal lubricant passageway with the lubricated area. The spindle has radially, diametrically opposed key recesses adjacent the spindle outer end, the key recesses being spaced away from the spindle longitudinal lubricant passageway. A C-shaped flexible retainer has coaxial end portions that are spread apart to extend through openings or slots in a nut and then into the key recesses to lock the nut in threaded position on the spindle. Since the key recesses do not communicate with the longitudinal lubricant passageway, they do not interfere with lubrication of the spindle.
