YQAD-013 074105251AC Crankshaft Pulley For Audi 08-18Product Description Crankshaft Pulley The crankshaft pulley (harmonic balancer) is mounted on the end of the crankshaft. Its purpose is to turn the drive belts that operate the engine accessories (alternator, air conditioning compressor, etc.) Symptoms of a Bad or Failing Crankshaft Pulley Knocking noise Engine accessories may stop working Crankshaft Pulley Related Repair Advice The crankshaft bolt securing the pulley can loosen, affecting the operation of the pulley The harmonic balancer includes a rubber insert between the center portion of the crankshaft pulley and the outer surface; this is what drives the belts The rubber insert can become damaged, resulting in an abnormal noise. The outer surface can also "slip" on the rubber insert, which can affect the ability to set the ignition time on older enginesAn automobile engine crankshaft pulley structure The pulley refers to the flywheel connected to the crankshaft of the engine.  It was originally designed to drive the camshaft to rotate to drive the engine accessories, such as controlling the engine's gas distribution system. When the engine is running, the stroke of the piston (up and down movement) valve The pulleys are generally made of cast iron as the timing action of the camshaft opens and closes in sequence. At present, the belt pulley is generally fixed by bolts, and the bump on the front end of the crankshaft of the engine is stuck in the square hole in the center of the pulley to achieve a fixed connection with the crankshaft.  When the engine is running, the crankshaft vibrates violently under the drive of the cylinder piston.  The running of the bolt will cause the loosening of the bolt. In the prior art, the static friction between the front end of the bolt and the inner wall of the fixing hole is mainly used to prevent the bolt from loosening. However, this method will cause pressure on the bolt to deform it and eventually destroy the bolt, causing the bolt to loosen again; when the pulley is connected to the belt for conduction because the belt is stretched by high strength for a long time to cause self-aging, it is easy to take off the pulley phenomenon. In the prior art, limit plates are generally installed at both ends of the pulley, but the belt is easy to separate The friction of the limiting plate causes loss.  Product ParametersITEM:SAP Crankshaft PulleyOEM:AcceptMOQ:1 pcs (If the goods have ex-stock, small quality will be available)BRAND:SAP Brand or Customer's BrandPACKING:Natural Packing or Packing as Customers requiredPAYMENT:L/C, T/T, Western Union, MoneyGram.etc,WARRANTY:12 MonthsPORT:SHANGHAI/NINGBOADVANTAGE:Good Quality and Competitive PriceSAMPLE:Customized SampleQuality:Produce According to ISO/TS 16949:2002 StandardTEAM:Powerful Production and R&D Capability  Company ProfileAnhui Strong Auto Parts Co., Ltd. is a professional manufacturer of many kinds of automobile control arms and automobile pulleys founded in 1995.
