Description
What does a valve adjusting shim do?
This precision-ground component serves as a critical spacer within the engine valve train, specifically designed to bring valve clearance back to the manufacturer's specified tolerance. By sitting between the rocker arm and the valve stem, it ensures the valve seats fully on every cycle, preventing compression loss and protecting the valve seating face from damage.Vehicle and engine compatibility
This specific 2.10 mm shim is compatible with Volvo NH12 trucks featuring the D12C engine. It is engineered to withstand the continuous impact loading inherent in heavy commercial vehicle diesel engines through high-strength components.Installation and maintenance
During installation, technicians should ensure the shim seat is clean and lightly lubricated to prevent scoring marks upon first start-up. It is essential to measure each valve individually, as clearances can vary between cylinders even within the same engine model.Troubleshooting and selection
To maintain optimal engine health, check valve clearances at the manufacturer's recommended mileage or operating-hour intervals. Using a shim with the correct thickness is vital to prevent premature wear of the contact surfaces and to maintain consistent engine timing.OE cross-reference
1300 05 003 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547969.Other OEMs
