Description
What does a valve adjusting shim do?
This precision-ground shim acts as a critical component within the engine valve train, specifically designed to maintain the correct valve clearance in heavy commercial vehicle diesel engines. By sitting between the rocker arm or cam follower and the valve, it ensures the valve seats fully during every cycle, preventing compression loss and maintaining engine timing accuracy.Compatibility with Volvo NH12 engines
This specific component is engineered for use in Volvo NH12 vehicles equipped with D12C engines. It serves as a reliable replacement for original components, helping workshop technicians maintain engine efficiency through precise clearance adjustment. It is also fitted to other heavy commercial vehicle engines requiring specific thickness tolerances.Installation and maintenance guidance
When installing this shim, technicians should ensure the shim seat is clean and lightly lubricated to prevent scoring upon initial start-up. It is vital to measure each valve individually to ensure the exact 3.55 mm thickness is applied where required, as clearances must be calibrated to specific engine requirements to avoid premature wear of the contact surfaces.Maintenance and performance
Regularly checking valve clearances at manufacturer-recommended intervals helps prevent damage to the valve seating face and maintains optimal combustion efficiency.OE cross-reference
1300 05 032 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677360.Other OEMs
