This rocker arm is a critical component within the valve train system of Volvo excavators, responsible for transferring the motion from the camshaft to the valves. Manufactured with high-grade materials and precision machining, it offers superior durability and wear resistance compared to a worn rocker arm that may have a pitted or uneven surface. Operators might notice increased engine noise, misfires, or a loss of engine power when a rocker arm begins to fail.

Failure Symptoms

An audible ticking or tapping noise from the engine, particularly at idle, often indicates a failing rocker arm. This can progress to rough engine running, intermittent misfires, and a noticeable decrease in engine power as the valve train's efficiency is compromised. Continued operation with a damaged rocker arm can lead to severe engine damage.

Installation Tip

Ensure the valve lash is correctly adjusted after installing the new rocker arm to maintain proper valve timing and operation. Do not overtighten the rocker arm adjusting screw, as this can damage the valve stem tip.

Service Note

Inspect the camshaft and valve stem tips for wear or damage when replacing the rocker arm.
