Description
What does a valve adjusting shim do?
This precision-engineered shim is designed to maintain exact valve clearance within the engine valve train of heavy commercial vehicle diesel engines. By providing a calibrated thickness, it ensures the valve seats fully during every cycle, preventing compression loss and protecting the valve seating face from premature wear.Engine compatibility and fitment
This component is compatible with various heavy-duty engine series, including Volvo NH12 (D12C), Renault Trucks Magnum (DXi12), Volvo VNL (D12), Volvo FH12 (D12C, D12D), Volvo FM12 (D12C, D12D), Volvo FM10 (D10A), Volvo VHD (D12), and Volvo FH16 (D16C). It is also fitted to several other heavy commercial vehicle engines through specific OE cross-references.Installation and maintenance guidance
For optimal performance, technicians should ensure the shim seat is clean and lightly lubricated before installation. It is critical to measure each valve individually rather than assuming uniform clearance across all cylinders. Always verify clearances after assembly to ensure they meet the manufacturer's specified tolerances.Reliability and selection
Using high-strength components helps prevent clearance drift caused by improper material hardness or poor parallelism. This ensures long-term reliability under continuous impact loading in demanding operating environments.OE cross-reference
1300 05 012 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547978.Other OEMs

FAQ
What is the function of a valve adjusting shim?
A valve adjusting shim acts as a precision spacer that brings the valve clearance to the exact tolerance required by the engine manufacturer, ensuring full valve seating.
Which engines are these shims compatible with?
These shims are compatible with several heavy-duty engines including Volvo D10A, D12, D12C, D12D, and D16C series, as well as Renault Trucks DXi12 engines.
How do I ensure I am selecting the correct thickness?
Selection should be based on the specific engine code and OE reference. Even within the same model series, different engine families may require different shim grades.
What are the symptoms of incorrect valve clearance?
Incorrect clearance can lead to compression loss, increased engine noise, or premature wear on the valve seating face and rocker arms.
What are the OE reference numbers of this part?
1300 05 012 directly replaces Volvo OE number 1547978.
