Abstract
A rack lubricator is bolted to a drive pinion housing. The lubricator supports a porous felt gear on a rotatable shaft. Lubricant is ported through the shaft to the inner surface of the gear, and the gear wicks the lubricant onto the rack teeth, thereby coating the surface of the rack with minimal lubricant as the felt gear rolls with the rack.
