Description
This precision-ground shim is a critical component of the engine valve train, designed to maintain exact valve clearance in heavy commercial vehicle diesel engines. By providing a measured 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.
This specific part is engineered for use in Volvo NH12 trucks equipped with D12C engines. It serves as a reliable replacement for worn or improperly sized shims to restore engine timing and efficiency. The component is built using high-strength materials to withstand the continuous impact loading inherent in high-pressure diesel engine operation.
When performing engine maintenance, it is vital to measure each valve individually to ensure the correct grade is selected. For professional technicians, we recommend cleaning the shim seat thoroughly and applying a light layer of oil before assembly to prevent scoring during initial start-up. Always verify all clearances before final assembly to ensure the engine operates within manufacturer specifications.
Consult your authorized distributor for more information on compatibility and selection.
