Original BMW Camshaft Sprocket Central Bolt M10 x 1 x 80 for BMW 550i, 650i, 750i, Alpina B7, X5, and X6 V8 (2008–2014)

On the N63 and S63 V8 BMWs, the camshaft sprocket rides on this Original BMW central bolt, an M10 x 1 x 80 fastener for the 550i, 650i, 750i, Alpina B7, X5, and X6. It clamps the timing sprocket to the end of the camshaft so the timing chain drives the camshaft without slipping. BMW calls it a central screw. Each bolt weighs 62 g (0.1 lb), is made in Slovakia, and is sold individually. BMW shows production of this number beginning in July 2008.

Original BMW Parts carry a 24-month parts warranty.

The bolt is one-time use. BMW requires that all bolts removed during timing chain work be replaced with new ones, so plan to buy one for every sprocket bolt you take out. BMW's parts data ties this number to the N63 V8 in the F07, F10, F11, F12, F13, F01, F02, F04, E70, and E71, and to the S63 in the X5 M and X6 M. It is also used on N74 V12 models outside our vehicle coverage.

Common Questions

Can I reuse the camshaft sprocket bolts?
No. BMW requires new bolts for every one removed during timing chain service.

How many do I need?
The bolt is sold individually, so order one for each camshaft sprocket bolt you remove.

Fresh sprocket bolts are a small cost on a big V8 timing job.
