Abstract
A two step rocker assembly is provided having a lever body, a first roller assembly mounted to the lever body, and a center shaft extending through the first roller assembly. A second shaft extends through the lever body and defines a first pivot point. A coupling lever is pivotally connected to the second shaft and has an opening for receiving the center shaft. The coupling lever is rotatable about the first pivot point. A latch pin is mounted to the lever body. A second roller assembly is mounted on the center shaft. A spring lever is pivotally connected to the second shaft and is connected to the center shaft. The spring lever is rotatable about the first pivot point. A spring member is mounted on the lever body and engages the spring lever to bias the spring lever and the center shaft into the first position.
