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 acting as a spacer between the cam follower and the valve, it ensures that 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 3.00 mm thickness is compatible with various Volvo models including the VHD, VNL, FM12, FH12, FH16, FM10, and NH12 engines such as the D12, D16C, and D10A series. It is also suitable for Renault Trucks Magnum engines equipped with the DXi12 engine. These components are essential for maintaining engine timing and efficiency in heavy-duty applications.Installation and maintenance guidance
For optimal performance, technicians should clean the shim seat and apply a light layer of oil before installation to prevent scoring marks upon first start-up. It is vital to measure each valve individually rather than assuming uniform clearance across all cylinders. Always verify clearances after assembly and consider renewing the valve cover gasket during the service interval.Selection and performance
Proper selection of shim thickness is crucial to prevent side loading or rapid clearance drift. Using high-strength components ensures that the shim withstands continuous impact loading without deforming under the cam profile.OE cross-reference
1300 05 021 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1677349.Other OEMs
