Description
What does a valve adjusting shim do?
This valve adjusting shim is a precision-ground component designed to maintain exact valve clearance within the engine's valve train. By providing a precise thickness, it ensures that the valve seats fully on every cycle, which is critical for maintaining compression and preventing engine misfire or mechanical wear.Compatibility with Volvo VNL D12
This specific 2.20 mm shim is compatible with Volvo VNL trucks equipped with D12 engines. It serves as a reliable replacement for original components, ensuring the rocker arm and cam follower maintain the manufacturer-specified tolerances required for heavy-duty operation.Installation and maintenance guidance
For proper installation, technicians should ensure the shim seat is clean and lightly lubricated before assembly to prevent scoring during initial start-up. It is essential to measure each valve individually to ensure the correct grade is selected, as clearances must be precise to avoid premature wear of the valve seating face.Ensuring engine performance
Regular inspection of valve clearances according to manufacturer intervals helps prevent compression loss and maintains engine efficiency throughout the service life of the vehicle.OE cross-reference
1300 05 005 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547971.Other OEMs

FAQ
What is the purpose of a valve adjusting shim?
A valve adjusting shim is used to bring the valve clearance in diesel engines back to the manufacturer's specified tolerance by adding measured thickness between the cam follower and the valve.
Can I use any shim thickness for my engine?
No, shims must be selected based on precise measurements or OE references, as even slight deviations can cause compression loss or damage to the valve seating face.
How often should valve clearances be checked?
Valve clearances should be checked at the mileage or operating-hour intervals specified by the vehicle manufacturer to prevent rapid wear of contact surfaces.
What are the symptoms of incorrect valve clearance?
Incorrect clearance can lead to compression loss, increased engine noise, and accelerated wear of the rocker arm or cam follower components.
What are the OE reference numbers of this part?
1300 05 005 directly replaces Volvo OE number 1547971.
