Multiquip 11425011290 Support Rocker Arm L40 AD - OEM Replacement Part

The support rocker arm is a critical valve train component in the Yanmar L40AD diesel engine that maintains proper valve timing and operation in the MT76D tamping rammer. This component supports the rocker arm assembly, ensuring accurate valve opening and closing sequences essential for the four-cycle engine's performance and the rammer's powerful compacting force delivery.

The MT76D rammer is equipped with an air-cooled, four-cycle Yanmar diesel engine that transmits power through a centrifugal clutch engagement system. The rocker arm support plays a vital role in maintaining the engine's valve train geometry and timing, directly affecting the rammer's ability to develop optimal compacting force at the tamper foot. Worn or damaged rocker arm supports can lead to irregular engine operation, loss of power, abnormal engine sounds, and reduced tamping performance.

This part is essential for maintaining the MT76D's transmission of power and ensuring the machine operates smoothly during soil compacting applications including road work, embankments, reservoirs, and backfilling for pipeline and cable installation projects.

• MT76D Tamping Rammer
