The cam follower group consists of the injector cam followers, valve cam followers, cam follower shafts, cam follower housing, and the valve and injector push rods. The N14 uses the crowned roller design cam follower. This design has been used since November, 1982.
NOTE: Label or tag all of the cam follower components with the position of the housing on the engine and their relative position to the other components removed from the housing. Many of the cam follower components are interchangeable; however, due to wear patterns, they must be installed in the same position from which they were removed.
