Description
This valve adjusting shim serves as a precision-ground spacer designed to maintain exact valve clearance within heavy commercial vehicle diesel engines. By providing the necessary thickness between the cam follower and the valve, it ensures the valve seats fully during every combustion cycle, preventing compression loss and protecting the valve seating face from premature wear.
This specific component is compatible with Volvo NH12 trucks equipped with the D12C engine. It is an essential part of the engine valve train, ensuring that the mechanical clearance remains within the strict tolerances required for high-performance diesel operation in heavy-duty applications.
For optimal performance, technicians should clean the shim seat and apply a light layer of oil before installation to prevent scoring during initial start-up. It is critical to measure each valve individually during service, as each cylinder may require a different thickness to maintain correct clearance across the entire engine.
When replacing components in the valve train, always verify clearances after assembly and consider renewing the cylinder head cover gasket to ensure a proper seal.

FAQ
What is the function of this shim?
A valve adjusting shim acts as a precision spacer that brings valve clearance back to the manufacturer's specified tolerance, ensuring the valves seat fully in the cylinder head.
Which vehicles is this part compatible with?
This 2.60 mm shim is designed for use in Volvo NH12 trucks featuring the D12C engine series.
How should I install a new valve adjusting shim?
Ensure the shim seat is clean and apply a light coating of oil before installation to prevent surface scoring on first start-up.
Can I use a sanded or ground shim?
No, you should never grind a shim to adjust thickness; sanding removes the hardened surface layer and reduces its service life.
What are the OE reference numbers of this part?
1300 05 013 directly replaces Volvo OE number 1547979.
