Description
What does a valve adjusting shim do?
This precision-ground shim is a critical component within the engine valve train, designed to maintain exact valve clearance in heavy commercial vehicle diesel engines. By sitting between the rocker arm or cam follower and the valve stem, it ensures the valve seats fully during every cycle, preventing compression loss and protecting the valve seating face from premature wear.Engine compatibility and fitment
This specific 3.30 mm thickness is compatible with several Volvo engine configurations, including the D12C, D12D, D10A, D16C, and D12 engines found in models such as the NH12, FH16, FM12, FM10, VNL, and VHD. It is also suitable for Renault Trucks Magnum with DXi12 engines. Precise fitment is essential for maintaining optimal engine timing and performance.Installation and maintenance guidance
For professional technicians, it is vital to clean the shim seat thoroughly and apply a light coating of oil before installation to prevent scoring during initial startup. We recommend measuring each valve individually rather than assuming uniform clearance across all cylinders to ensure the engine operates within manufacturer tolerances.Troubleshooting and inspection
Regular inspection of valve clearances during scheduled maintenance intervals helps prevent excessive wear on the cam profile and rocker components. If symptoms of improper clearance appear, such as increased engine noise or power loss, always verify the exact required thickness before replacement.OE cross-reference
1300 05 027 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677355.Other OEMs
