Who We Are
The 4115R612 Rocker Arm Assembly is a vital mechanical component for Perkins diesel engines, particularly those in the 1104 and 1106 series. Its primary function is to transfer motion from the camshaft to the intake and exhaust valves, ensuring accurate valve lift, proper combustion timing, and long-lasting engine performance.
A damaged or worn rocker arm assembly can lead to engine misfiring, power loss, irregular valve action, and premature wear.
