{"product_id":"bmw-adjusting-pulley-3","title":"Original BMW Adjusting Pulley with Lever for S65 Accessory Belt Drive, BMW M3 (2008)","description":"\u003cp\u003eThis Original BMW adjusting pulley with lever is the drive belt tensioner pulley that keeps the accessory drive belt under tension on the 2008 BMW M3 with the S65 engine. BMW calls it the adjusting pulley with lever. The name describes the assembly: a belt pulley carried on a pivoting arm, not a loose idler wheel. It comes as one complete unit, so the pulley and lever arrive together and no separate arm is needed. BMW shows production of this number starting in June 2007. An accessory drive belt turns the engine's belt-driven accessories, and the tensioner holds enough load on that belt to stop it slipping as engine speed and accessory demand change.\u003c\/p\u003e\n\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\n\u003cp\u003eA failing tensioner usually shows up as a belt that bounces, hops, or wobbles because the arm can no longer hold even, constant pressure. A worn pulley bearing on the arm adds drag and makes the problem worse. Before you order, check the other belt-driven accessories and idler pulleys by hand. A dragging power steering pump or A\/C compressor can cause intermittent drag that looks like a tensioner fault. When the tensioner itself has slack, replace it and its associated components together as a full belt service.\u003c\/p\u003e\n\u003ch3\u003eTechnical Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (genuine part)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-28-7-838-196\u003c\/li\u003e\n\u003cli\u003eBMW part name: adjusting pulley with lever\u003c\/li\u003e\n\u003cli\u003eFunction: accessory drive belt tensioner pulley\u003c\/li\u003e\n\u003cli\u003eEngine: S65, BMW M3\u003c\/li\u003e\n\u003cli\u003eProduction start: June 2007\u003c\/li\u003e\n\u003cli\u003eSold as: one assembly, pulley and lever together\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on Original BMW Parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow can I tell whether the tensioner is the problem?\u003c\/strong\u003e\u003cbr\u003eWatch for a belt that bounces or hops and a pulley bearing that feels rough.
