Original BMW VANOS Camshaft Sprocket Central Bolt M10x1x75 for BMW 5, 6, 7 Series, Alpina B7, and X5 (2002–2010)

Made in Slovakia, Original BMW central screw 11-36-7-501-423 is the M10x1x75 bolt that secures the VANOS camshaft sprocket on the N62 V8 and N73 V12 engines in the BMW 5 Series, 6 Series, 7 Series, Alpina B7, and X5 from 2002 to 2010. It is a one-time-use bolt. Install a new one whenever the timing chain assembly is serviced. Each bolt weighs 62 g, about 0.1 lb, and BMW has produced this number since July 2001. On a variable valve timing engine, a central bolt of this kind clamps the sprocket and adjuster to the end of the camshaft, so its clamping force holds the timing together.

Original BMW Parts carry a 24-month parts warranty.

BMW calls this part a central screw, and it supersedes the earlier 11-36-0-150-558. BMW rates the change as exchangeable retrospectively, so the current bolt replaces the older number on any engine that used it. The same bolt covers the first-generation N62, the later N62N in the 550i, 650i, 750i, and X5 4.8i, and the N73 twelve in the 760i and 760Li.
