Land Rover Part Number: LR023004 - Timing Chain Tensioner
LR023004 is a timing chain tensioner. Fitted within the timing gear of the 4.4L DOHC DITC V8 diesel engine, it controls chain tension to reduce slack and limit accelerated wear on guides and sprockets, helping to maintain correct camshaft and crankshaft timing under varying oil pressure and thermal conditions. Correct tension reduces audible chain noise and lowers the risk of timing deviation that can damage valves and pistons. The tensioner operates continuously during engine running and reacts to changes in oil pressure and thermal expansion; replacement is recommended if the tensioner sticks, produces abnormal noise, or if adjacent timing components show visible wear. Use the compatibility data below to confirm fitment against your V.I.N.
