Description
What does a valve adjusting shim do?
This valve adjusting shim is a precision-ground component designed to bring valve clearance in diesel engines to the exact tolerance required by the manufacturer. It functions by adding measured thickness between the rocker arm or cam follower and the valve, ensuring the valve seats fully during every cycle. Using high-strength components helps prevent compression loss and protects the valve seating face from premature wear.Compatibility with Volvo engines
This specific shim is designed for use in Volvo FH12 trucks equipped with D12C engines. It serves as a reliable replacement for original components, maintaining the precise geometry required for heavy-duty engine operation. It is also fitted to other heavy commercial vehicle applications where similar engine specifications are utilized.Installation and maintenance
When performing maintenance, technicians should verify the thickness requirements against the engine's service specifications. Proper installation of these shims is critical to prevent irregular valve opening or excessive mechanical noise. Ensuring the shim is seated correctly within the rocker assembly maintains the integrity of the engine's timing and fuel efficiency.Troubleshooting and selection
If you observe unusual engine knocking or a drop in compression, it may indicate that the valve clearance requires adjustment. Consult your authorized distributor to ensure you have the correct thickness grade for your specific engine configuration.OE cross-reference
