1547983 Volvo FH16 D16C 2.80 mm Valve Shim

What does a valve adjusting shim do?

This precision-ground shim is an essential component of the engine valve train, specifically designed to maintain exact valve clearance in heavy commercial vehicle diesel engines. By sitting between the rocker arm or cam follower and the valve, it compensates for wear and ensures the valve seats fully during every combustion cycle, preventing compression loss and protecting the valve seating face.

Compatibility with Volvo FH16 D16C

This specific 2.80 mm grade is compatible with Volvo FH16 engines featuring the D16C engine code. It is engineered to withstand the continuous impact loading inherent in high-pressure diesel combustion environments. Using a shim of the correct thickness is critical to maintaining the precise tolerances required for optimal engine performance and fuel efficiency.

Installation and maintenance guidance

When performing engine maintenance, technicians should ensure the shim seat is clean and lightly lubricated before installation to prevent scoring upon start-up. It is highly recommended to measure each valve individually rather than assuming uniform clearance across all cylinders. Always verify clearances after assembly and check for any signs of uneven wear on the contact surfaces.

Ensuring proper engine performance

Proper selection of shims prevents excessive noise and mechanical wear within the cylinder head. For reliable engine operation, always cross-reference dimensions with the original equipment requirements during service intervals.
