Description
What does a valve adjusting shim do?
A valve adjusting shim is a precision-ground spacer used in heavy commercial vehicle diesel engines to bring valve clearance back to the manufacturer's specified tolerance. It is fitted between the rocker arm, valve bridge, or cam follower and the valve, adding measured thickness into the chain between the cam profile and the valve so the valve seats fully on every cycle.Compatibility with Volvo VNL D12
This specific component is designed for Volvo VNL D12 engines. It ensures that the valve train maintains the exact clearance required for efficient combustion and prevents compression loss. It is highly compatible with Volvo systems in various heavy-duty applications.Installation and maintenance guidance
When performing maintenance, technicians should ensure the shim seat is clean and lightly lubricated before assembly to prevent scoring marks upon start-up. It is critical to measure each valve individually, as different cylinders may require different grades to achieve the correct clearance within the engine family.Maintenance and troubleshooting
Regularly checking valve clearance according to manufacturer intervals helps prevent rapid wear of contact surfaces. Using a precision-made shim ensures dimensional consistency under continuous impact loading in high-duty cycles.OE cross-reference
1300 05 020 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677348.Other OEMs

FAQ
What is the function of a valve adjusting shim?
It acts as a precision-ground spacer that brings valve clearance in heavy commercial vehicle diesel engines to the exact tolerance set by the manufacturer.
Which engines are this shim compatible with?
This specific 2.95 mm shim is designed for use in Volvo VNL D12 engines to maintain proper engine timing and seating.
How should I install a new valve adjusting shim?
Clean the shim seat thoroughly and apply a light layer of oil before assembly to prevent scoring during the initial start-up.
Why is it important to measure each valve individually?
Each cylinder may require a different grade; assuming one measurement applies to all can lead to incorrect clearances and engine damage.
What are the OE reference numbers of this part?
1300 05 020 directly replaces Volvo OE number 1677348.
