The improved rocker arm includes a locking assembly for releasably securing the rocker arm to the shaft to prevent pivoting of the rocker arm during a positive power operation. The locking assembly includes a releasable latching assembly located on one of the rocker arm and the shaft. The locking assembly also includes a latch receiving recess located on another of the rocker arm and the shaft. The releasable latching assembly engages the latch receiving recess during a positive power operation. The releasable latching assembly disengaging the latch receiving recess during an engine braking operation such that the rocker arm can pivot about the shaft.
In a rocker arm assembly for an engine brake assembly, said rocker arm assembly comprising a rocker arm pivotally mounted on a shaft, said rocker arm having a first end and a second end, wherein said first end includes a cam follower and said second end includes an actuator assembly for operating at least one valve during a braking operation, the improvement comprising:
