Land Rover Part Number: ERR4682 - Rocker Shaft
ERR4682 is a rocker shaft. Fitted into machined bores in the cylinder head, it locates and supports the line of rocker arms on the 2.5L 200Tdi engine as used in vehicles with a 5-speed manual transmission. The shaft provides a stable pivot so camshaft motion is transmitted to the inlet and exhaust valves; correct positioning maintains valve geometry and alignment across the rocker assembly, keeping contact between rocker pads and valve stems within design tolerances. It interfaces directly with the rocker arms and their adjusters, so correct installation is required to avoid uneven wear or valve timing irregularities. Use the compatibility data below to confirm fitment against your V.I.N.
