Abstract:
A two-step rocker arm assembly is provided having an arm member and a first roller assembly rotatably mounted with respect to the arm member and defining a generally C-shaped opening. A shaft member rotatably supports a second and a third roller assembly. The shaft member extends through the generally C-shaped opening and is selectively translatable therein to guide the second and third roller assemblies with respect to the arm member. A coupling lever is mounted with respect to the shaft member and is operable to selectively retain the shaft member with respect to the arm member for unitary movement therewith.
