Land Rover Part Number: 1418836 - Timing Chain Tensioner Arm
1418836 is a Timing Chain Tensioner Arm. Fitted in the timing gear of the 3.6 V8 32V DOHC EFI Diesel engine, this arm locates the tensioner against the timing chain to control contact with the camshaft and crankshaft sprockets. The arm transfers force from the hydraulic tensioner to the chain guide surface, positioning the tensioner pad to control chain slack and alignment; excessive wear, scoring or breakage can allow increased chain movement, producing noise, accelerated component wear or timing deviation between cam and crank. The component mounts within the timing cover area and works with tensioner hydraulics and guides to retain correct chain running geometry on affected Range Rover and Range Rover Sport models.
