1300 05 017 2.80 mm Engine Valve Shim for Volvo

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 specific thickness of 2.80 mm, it sits between the rocker arm or cam follower and the valve stem, ensuring the valve seats fully during every combustion cycle. This precision is critical for maintaining engine timing and preventing compression loss in heavy commercial vehicle diesel engines.

Engine compatibility and fitment

This specific 2.80 mm shim is compatible with several Volvo engine series, including the D12, D10A, D12D, D12C, and D16C engines found in models such as the VNL, VHD, FH12, FH16, FM12, FM10, and NH12. It is also suitable for Renault Trucks Magnum equipped with DXi12 engines. For accurate fitment, always verify the thickness against the existing shim or the manufacturer's specifications.

Installation and maintenance guidance

During installation, technicians should ensure the shim seat is clean and lightly lubricated to prevent scoring upon initial startup. It is essential to measure each valve individually during maintenance intervals to ensure each cylinder maintains the correct clearance. Using a shim of the correct grade prevents premature wear on the valve seating face.

Troubleshooting and selection

Regularly checking valve clearances according to manufacturer intervals helps prevent engine performance degradation. If symptoms of improper clearance arise, such as increased noise or loss of power, replacing worn shims with these high-strength components is recommended. Consult your authorized distributor to check the compatibility list.
