<p>The internal combustion engine includes a cast cylinder head having as-cast alignment ribs (26, 28) that align a squared-off fulcrum (56) in the rocker assembly. The rocker arm (42) also has two substantially flat surfaces that engage the planar sides of the fulcrum (56) to minimize lateral movement of the rocker arm (42). The fulcrum (56) is received between the cast alignment ribs (26, 28). The ribs are biased from a major axis to insure proper fulcrum alignment during assembly without the use of a jig.</p> |
