Removal
1. See Figure 3-114. Remove screws (4) and remove sec-
ondary cam chain tensioner (3).
Wear safety glasses or goggles when removing or
installing retaining rings. Retaining rings can slip from the
pliers and could be propelled with enough force to cause
serious eye injury. (00312a)

ondary cam chain. Maintaining the original direction of
rotation during assembly may prolong service life.
