Description

What does a valve adjusting shim do?

This valve adjusting shim is a precision-ground spacer designed to maintain the exact valve clearance required for heavy commercial vehicle diesel engines. By sitting between the rocker arm or cam follower and the valve, it ensures that the valve seats fully on every cycle, preventing compression loss and protecting the valve seating face from premature wear.

Vehicle and engine compatibility

This specific part is compatible with Volvo NH12 trucks featuring the D12C engine. It is essential for maintaining the timing and efficiency of the engine's valve train system in heavy-duty applications.

Installation and maintenance

During installation, technicians should verify that the shim thickness matches the manufacturer's specifications for the specific engine code. Proper placement is critical to prevent side loading or uneven wear on the cam profile. Always check for surface parallelism to ensure long-term durability under continuous impact loading.

Troubleshooting guidance

If you observe increased engine noise or a drop in compression, it may indicate that the valve clearance has drifted due to worn shims. Consult your authorized distributor to ensure you select the correct grade for your specific engine configuration.

OE cross-reference

1300 05 009 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547975.
