Original BMW Right Timing Chain Tensioner, Cylinders 1 to 4, for BMW 545i, 550i, 645Ci, 650i, 7 Series, and X5 V8 (2002–2010)

On the BMW N62 and N62N V8, this Original BMW timing chain tensioner rail, part number 11-31-7-533-462, guides the timing chain on the right-hand cylinder bank, cylinders 1 to 4, in 2002–2010 5 Series, 6 Series, 7 Series, and X5 models. BMW names it simply the chain tensioner. A tensioner rail presses against the slack side of the timing chain so the chain stays tight against its sprockets as the engine runs. One is used per engine. It weighs 138 g (0.3 lb), and production of this number began in March 2005. It is sold as a single piece.

Original BMW Parts carry a 24-month parts warranty.

This part is specific to the right bank. This rail serves the right bank, cylinders 1 to 4, which is the passenger side of a left-hand-drive car. Do not substitute the left-bank part. BMW applies this number to both the N62 and the N62N, covering the E60 and E61 5 Series, the E63 and E64 6 Series, the E65, E66, and E67 7 Series, and the E53 and E70 X5, with and without the facelifts.
