Description
What does a valve adjusting shim do?
This valve adjusting shim is a precision-ground component designed to bring valve clearance in heavy commercial vehicle diesel engines to the exact tolerance set by the manufacturer. It is fitted within the valve train to ensure the valve seats fully on every cycle, preventing compression loss and protecting the valve seating face.Engine compatibility and fitment
This specific part is compatible with Volvo FM12 trucks equipped with D12C engines. It is also fitted to other heavy commercial vehicles within the same engine family. For accurate fitment, always cross-reference the thickness and diameter with the removed shim or the engine specification.Installation and maintenance guidance
For professional installation, ensure the shim seat is clean and lightly lubricated before assembly to prevent scoring marks during the first start-up. Technicians should measure each valve individually rather than assuming uniform clearance across all cylinders. It is recommended to re-verify all clearances before finalizing the assembly.Component durability
Using high-strength components ensures that the shim can withstand continuous impact loading from the cam profile without deforming or losing its dimensional accuracy.OE cross-reference
1300 05 038 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677366.Other OEMs
