Description
What does a valve adjusting shim do?
This valve adjusting shim functions as a precision spacer within the engine's valve train, ensuring that valve clearance remains within the exact tolerances required for optimal combustion. By sitting between the rocker arm or cam follower and the valve, it compensates for wear and maintains the correct gap, allowing the valve to seat fully during every engine cycle.Compatibility and engine fitment
This specific component is designed for use in Volvo FM12 trucks equipped with D12D engines. It serves as a reliable replacement for worn or incorrectly sized shims, helping to prevent compression loss and protecting the valve seating faces from premature damage. Check the compatibility list to ensure exact fitment for your specific engine configuration.Installation and maintenance guidance
When performing maintenance, technicians should measure each valve individually to determine the required thickness grade. It is essential to clean the shim seat and apply a light film of oil before assembly to prevent scoring upon initial start-up. Always verify clearances after installation to ensure the engine operates within manufacturer specifications.Selection and performance
Proper shim selection is critical for preventing side loading or uneven wear on the cam follower. Using high-strength components ensures that the shim can withstand continuous impact loading without deforming under heavy-duty operating conditions.OE cross-reference
1300 05 034 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677362.Other OEMs

FAQ
What is the function of a valve adjusting shim?
It is a precision spacer that adjusts the gap between the cam follower and the valve, ensuring correct clearance and full seating in diesel engines.
Which engines is this shim compatible with?
This 3.65 mm shim is specifically designed for Volvo FM12 engines featuring the D12D engine configuration.
Why should I measure valves individually during adjustment?
Each cylinder may require a different thickness grade due to varying wear patterns; measuring individually ensures precise clearance across all valves.
How can I prevent premature wear on new shims?
Ensure the shim seat is perfectly clean and apply a light layer of oil during installation to prevent scoring during the first engine start-up.
What are the OE reference numbers of this part?
1300 05 034 directly replaces Volvo OE number 1677362.
