BMW files it in the engine timing chain group as a plain sprocket, and it is the lower gear of the chain drive that turns both camshafts. The part weighs 63 g, and BMW shows production starting in March 2011. It is made in Germany and sold as a single piece. A crankshaft sprocket rides on the nose of the crankshaft and sets the pace for the whole timing drive, so its tooth profile has to match the chain exactly.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eThe N20 and N26 timing drive uses one crankshaft sprocket and two camshaft sprockets, and this part is the crankshaft gear only. The two camshaft sprockets carry separate numbers, 11-36-7-583-818 and 11-36-7-583-819, so do not order this sprocket expecting it to fit a camshaft. On BMW's timing diagram it sits with the engine timing chain 11-31-7-516-074, the chain guides 11-31-7-592-877 and 11-31-7-592-850, the chain tensioner 11-31-7-567-680 with its gasket 11-31-7-631-972, and the camshaft adjuster sensor wheel 11-36-7-598-215. \u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW, Original BMW part\u003c\/li\u003e\n\u003cli\u003ePart number: 11-31-7-603-944\u003c\/li\u003e\n\u003cli\u003eBMW part name: sprocket, engine timing chain group (crankshaft position)\u003c\/li\u003e\n\u003cli\u003eEngines: N20 and N26 four-cylinder\u003c\/li\u003e\n\u003cli\u003eWeight: 63 g (0.1 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: March 2011\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Germany\u003c\/li\u003e\n\u003cli\u003eSold individually, one piece\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on Original BMW Parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs this the camshaft sprocket or the crankshaft sprocket?\u003c\/strong\u003e\u003cbr\u003eIt is the crankshaft sprocket.
