It is produced to original equipment tolerances and is intended to replace a worn, bent, cracked or journal-damaged original crankshaft without modification.\u003c\/p\u003e\u003cp\u003eKey Features: Each crankshaft is CNC-machined to original equipment dimensions, controlling main and rod journal diameters, journal run-out, stroke and thrust surfaces. Journals are ground and micro-polished to a fine surface finish to encourage reliable oil-film formation and reduce bearing wear during cold starts and sustained high load. The forged steel construction resists bending and torsional fatigue under high cylinder pressure, while dynamic balancing reduces vibration across the rev range. Consistent production tolerances mean the part can be fitted without the trial-and-error often associated with low-grade replacements.\u003c\/p\u003e\u003cp\u003eVehicle Compatibility: This part is listed for BMW, covering model families such as X5 X5 M50dX, X5 X5 30dX, X6 X6 30dX, 5' series 530d 155kW, X6 X6 40dX and X6 X6 M50dX. Documented fitment covers model years 1998-2023, 1997-2023 and 2004-2017. If a vehicle is not shown in the compatibility list, cross-reference the engine code and original reference number to confirm fitment.\u003c\/p\u003e\u003cp\u003eSpecifications: Key specifications: engine code N57; displacement 3.0L Diesel; cylinder configuration Inline 6 Cylinder; material Forged 42CrMoS4 Steel; size STD; condition New; warranty 12 Months. Measured characteristics include valve train 24 Valves. Production follows IATF 16949 ISO9001 quality management.\u003c\/p\u003e\u003cp\u003eOEM \/ Reference Numbers: This part is cross-referenced to 11218512217, 11217812954 and 11217799970. Match the numbers above against the markings on the removed part to be certain of correct identification.\u003c\/p\u003e\u003cp\u003eApplications: Typical uses include engine overhauls, bottom-end rebuilds, fleet maintenance and repair of vehicles withdrawn from service because of bearing failure or bottom-end noise. The part is a sensible stock item for workshops that service this engine family regularly and want to minimise vehicle downtime. Holding a standard-size unit in stock helps workshops complete rebuilds without waiting for machining or exchange parts.\u003c\/p\u003e\u003cp\u003eBenefits \/ Replacement Information: A new crankshaft removes the vibration, knocking and low oil pressure associated with worn journals or a bent shaft. Using a new standard-size shaft eliminates the turnaround time and uncertainty of reconditioning the original component. Accurate journal geometry and balance lower the load on bearings and the lubrication system, helping the rebuilt engine last.\u003c\/p\u003e\u003cp\u003eInstallation or Fitment Notes: Before fitting, confirm the part number, measure the main and rod journals, and check the block line bore and bearing tunnel condition. Fit new bearing shells, verify clearances against factory limits, and torque the caps in the specified order.\u003c\/p\u003e","brand":"Nanjing Woda Auto Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":41372126642248,"sku":"bmw-for-bmw-1998-2023-1997-2023-2004-2017-2009-2023-2007-2023-2010-2012-2009-2023-2010-2020-2011-2023-2011-2023-n57-n57-diesel-crankshaft-11218512217-for-bmw-series-3-0l-n57d30-oem-11218512217","price":420.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/9037\/4728\/files\/H2f94097655964e3c860ed8bac166242dF.webp?v=1789953943","url":"https:\/\/autocentreparts.co.nz\/products\/bmw-for-bmw-1998-2023-1997-2023-2004-2017-2009-2023-2007-2023-2010-2012-2009-2023-2010-2020-2011-2023-2011-2023-n57-n57-diesel-crankshaft-11218512217-for-bmw-series-3-0l-n57d30-oem-11218512217","provider":"Auto Centre Parts","version":"1.0","type":"link"}
