Abstract: A compliance spring assembly (50, 150) for applying a biasing force to a cam side (24) of a rocker arm (20A, 20B, 20C, 20D) to bias the cam side toward an adjacent cam (14). The compliance spring assembly includes a spring guide (52, 152) having a first end configured to engage the cam side of the rocker arm and a second end configured to slidingly engage a hole (36) in a fixed mount (32) positioned adjacent the cam side of the rocker arm. A compliance spring (62) engages a lower surface of the fixed mount and a spring mount (56, 156) formed on the spring guide. The compliance spring is compressed between the lower surface and the spring mount for apply the biasing force to the cam side of the rocker arm.
