This direct replacement idler pulley restores correct belt deflection and guidance around the accessory drive system, reducing abnormal bearing noise and friction associated with an ageing factory pulley. A straightforward replacement that protects the wider engine bay from the collateral damage a failed pulley can cause.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eDirect replacement for OEM part numbers 11287841228 · 11281748130 and related references – bolt-on fitment with no modification required\u003c\/li\u003e\n\u003cli\u003eHigh-quality metal and plastic construction comparable to factory quality – reduces abnormal bearing noise and friction caused by pulley ageing\u003c\/li\u003e\n\u003cli\u003eGuides the drive belt correctly around accessory attachments on M50, M52, M54, S50, S52, S54, S65, and S85 engine applications\u003c\/li\u003e\n\u003cli\u003ePrevents a seized or broken pulley from damaging the radiator, hoses, cooling fan, and surrounding engine bay components\u003c\/li\u003e\n\u003cli\u003eOffset bolt hole design – confirm your application before ordering (see compatibility notes below)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Drive Belt Deflection \/ Idler Pulley\u003c\/li\u003e\n\u003cli\u003eCompatible Engines: M50 · M52 · M54 · S50 · S52 · S54 · S65 · S85\u003c\/li\u003e\n\u003cli\u003eTensioner Type: Hydraulic Tensioner Only\u003c\/li\u003e\n\u003cli\u003eBolt Hole: Offset (not centred)\u003c\/li\u003e\n\u003cli\u003eOEM Replacement Part Numbers: 11287841228 · 11281726181 · 11281730571 · 11281738061 · 11281738605 · 11281748130 · 11281748131\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eFitment:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 3 Series E36 318i (1994–1995)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E36 325i · 325is (1992–1995)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E36 328i · 328is (1995–1998)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E46 323i · 323is · 323Ci (1998–2000)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E46 328i · 328Ci (1999–2000)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E46 325i · 325Ci · 325xi (2001–2005)\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E46 330i · 330xi · 330Ci (2001–2006)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series E39 525i (2000–2003)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series E39 528i (1998–2001)\u003c\/li\u003e\n\u003cli\u003eBMW 5 Series E39 530i (2001–2003)\u003c\/li\u003e\n\u003cli\u003eBMW X5 E53 3.0i (2001–2006)\u003c\/li\u003e\n\u003cli\u003eBMW Z3 E36 2.8i · 3.0i (1997–2002)\u003c\/li\u003e\n\u003cli\u003eBMW Z4 E85 2.5i · 3.0i (2003–2005)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eContents:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e1x Drive Belt Deflection \/ Idler Pulley\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eBenefits:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eEliminates abnormal belt noise and bearing friction associated with a worn or ageing idler pulley\u003c\/li\u003e\n\u003cli\u003ePrevents sudden pulley failure from causing collateral damage to radiator, hoses, fans, and other engine bay components\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on replacement restores correct belt deflection and drive system geometry immediately\u003c\/li\u003e\n\u003cli\u003eFactory-comparable quality ensures reliable long-term performance across the supported engine families\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eInstallation Notes:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with hydraulic tensioner vehicles only – will not fit mechanical tensioner applications\u003c\/li\u003e\n\u003cli\u003eThis pulley features an offset bolt hole – it cannot be used on models with a centred bolt hole.
