Description
What does a valve adjusting shim do?
This valve adjusting shim is a precision-engineered component designed to maintain exact valve clearance within the engine's valve train. By providing a specific thickness, it ensures that the valves seat fully and correctly during every combustion cycle, which is critical for maintaining engine compression and efficiency in heavy commercial vehicle engines.Compatibility and engine fitment
This specific 2.50 mm shim is compatible with Volvo VNL D12 engines. It serves as a reliable replacement to restore proper lash settings in the cylinder head assembly, ensuring the engine operates within the manufacturer's specified tolerances.Installation and maintenance guidance
For optimal results, technicians should clean the shim seat thoroughly and apply a light layer of oil before installation to prevent scoring during initial start-up. It is recommended to measure each valve individually rather than assuming uniform clearance across all cylinders, as each may require a different thickness to achieve perfect alignment.Troubleshooting and service tips
Regular inspection of valve clearances according to service intervals helps prevent premature wear on the rocker arms and cam followers. If you notice irregular engine noise or loss of power, verify the shim thickness against the required specifications to ensure correct valve lash adjustment.OE cross-reference
1300 05 011 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547977.Other OEMs

FAQ
What is the function of a valve adjusting shim?
A valve adjusting shim is a precision-ground component used to bring valve clearance back to the manufacturer's specified tolerance by adding measured thickness between the cam follower and the valve.
Which engines are this 2.50 mm shim compatible with?
This specific 2.50 mm thickness is designed for use in Volvo VNL D12 engines to ensure precise valve train adjustment.
How can I ensure I am using the correct shim thickness?
The correct grade should be determined by cross-referencing the OE part number or measuring the current clearance to ensure it matches the manufacturer's requirements.
What are the symptoms of incorrect valve clearance?
Incorrect clearance can lead to compression loss, irregular engine noise, or accelerated wear on the valve seating faces and rocker arms.
What are the OE reference numbers of this part?
1300 05 011 directly replaces Volvo OE number 1547977.
