Rocker Arm
Volvo

The rocker arm is a key component in the valve train system, translating camshaft motion into valve operation. Its precise movement controls the opening and closing of intake and exhaust valves, directly affecting engine performance and efficiency. Constructed from durable materials, it withstands high stresses and thermal cycles. Proper functioning of the rocker arm ensures optimal valve timing, which is critical for power output and emissions control. Regular inspection for wear or damage is recommended to prevent engine misfires or reduced performance. This component's reliability is essential for maintaining smooth engine operation in heavy-duty trucks.
