ABSTRACT:
An apparatus and method for lubricating an internal-combustion engine includes a shaft extending through a gearbox, a gear and a sliding sleeve coupled to rotate with the shaft and adapted to move axially along the shaft, a gearshift fork in mating engagement with the sliding sleeve and moveable parallel to the shaft, a rib in the gearbox adjacent the shaft, and a duct extending into the gearbox. The duct preferably directs a lubricant onto the gearshift fork and the sliding sleeve. Preferably, the rib directs the lubricant from the duct onto the gearshift fork and the sliding sleeve. In an alternative embodiment, at least some of the lubricant flung from the shaft, gear, and sliding sleeve contacts the rib and is directed onto the sliding sleeve and the gearshift fork. Further preferably, a projection extends from the rib to direct the lubricant onto the sliding sleeve and the gearshift fork.
