Description
What does a valve adjusting shim do?
This valve adjusting shim is a precision-ground component designed to maintain exact valve clearance within heavy commercial vehicle diesel engines. By providing a specific thickness between the rocker arm and the valve stem, it ensures the valve seats fully during every cycle, which is critical for maintaining engine compression and timing accuracy.Vehicle and engine compatibility
This specific 2.60 mm thickness is compatible with Volvo VNL trucks equipped with D12 engines. It serves as a reliable replacement for worn or incorrectly sized shims to restore the engine's mechanical timing to manufacturer specifications.Installation and maintenance guidance
For proper installation, technicians should ensure the shim seat is clean and lightly lubricated before assembly to prevent scoring. It is essential to measure each valve individually, as clearances may vary across different cylinders even within the same engine block.Troubleshooting and selection
Regularly checking valve clearances at manufacturer-recommended intervals helps prevent premature wear of the valve train components. Consult your authorized distributor for further assistance.OE cross-reference

FAQ
What is the function of a valve adjusting shim?
A valve adjusting shim is a precision component used to bring valve clearance in diesel engines back to the manufacturer's specified tolerance, ensuring the valve seats fully on every cycle.
