{"product_id":"bmw-protection-cap","title":"Original BMW Drive Belt Idler Pulley Protection Cap for BMW E70 X5 xDrive35d (2009–2013)","description":"\u003cp\u003eThe Original BMW protection cap, part 11-28-7-535-867, is the small dust cap that covers the drive belt idler pulley bolt and bearing on the E70 BMW X5 xDrive35d from 2009–2013. An idler pulley guides the accessory drive belt and spins on a sealed bearing held by a center bolt, and the cap closes over that bolt to keep dirt and water away from the bearing. BMW states this cap protects the idler pulley bearing and must be replaced if missing, or premature bearing failure can occur. It weighs 4 g, is made in Germany, and is sold as one cap. BMW shows production of this number starting in September 2004.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eA pulley left uncapped is the case BMW warns about. The same cap appears across a wide range of BMW six-cylinder belt drives, including N52 and N53 gasoline engines and the M57N2 diesel, so one part number covers many pulleys in BMW's range. For the X5 xDrive35d, BMW applies it to the E70 and E70 facelift with the M57N2 engine.\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: 11-28-7-535-867\u003c\/li\u003e\n\u003cli\u003eBMW part name: protection cap\u003c\/li\u003e\n\u003cli\u003ePosition: drive belt idler pulley\u003c\/li\u003e\n\u003cli\u003eWeight: 4 g (0.14 oz)\u003c\/li\u003e\n\u003cli\u003eSold as one cap\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Germany\u003c\/li\u003e\n\u003cli\u003eProduction start: September 2004\u003c\/li\u003e\n\u003cli\u003eEngine: M57N2 diesel (X5 xDrive35d)\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes a missing pulley cap really matter?\u003c\/strong\u003e\u003cbr\u003eBMW says it does.
