4462683 is a secondary timing tensioner for the right bank. Fitted to the upper timing gear of AJ V8 petrol engines, this tensioner maintains timing belt tension on the right cylinder bank by applying a measured axial load and working alongside the primary tensioner and idler components to keep the camshaft drive correctly tensioned and valve timing accurate. The unit mounts to the timing cover area and operates under engine oil or hydraulic control as specified by the engine design.
