Description
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 the necessary thickness between the rocker arm and the valve stem, it ensures that the valve seats fully and correctly during every combustion cycle, which is vital for maintaining compression and engine efficiency.Vehicle and engine compatibility
This specific 3.40 mm shim is compatible with Volvo NH12 trucks equipped with D12C engines. It serves as a reliable replacement for worn or improperly sized shims to prevent compression loss or damage to the valve seating face in heavy commercial vehicle applications.Installation and maintenance guidance
When performing engine maintenance, technicians should measure each valve individually to ensure the correct grade is applied. It is recommended to clean the shim seat thoroughly and apply a light film of oil before installation to prevent scoring during the initial startup of the engine.Maintenance importance
Regularly checking valve clearances at manufacturer-recommended intervals helps prevent premature wear of the contact surfaces and maintains the long-term reliability of the engine system.OE cross-reference
1300 05 029 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677357.Other OEMs
