Product Overview: This forged steel engine crankshaft is a direct-fit replacement component engineered for BMW N57 engines. The part is manufactured to original equipment dimensions, making it a practical solution when an original crankshaft has failed through bearing wear, scoring or fatigue cracking.
Key Features: CNC machining holds the main and rod journals, fillet radii, stroke and end-float to original equipment tolerances for accurate assembly. The journals are ground, hardened and micro-polished so the bearing shells receive a consistent oil film and run quietly from the first start. A nitrided or induction-hardened surface layer increases journal hardness and wear resistance for long service life. The finished component is inspected and packed to protect its machined surfaces during transport and storage.
Vehicle Compatibility: This part is listed for BMW, covering model families such as X5 X5 30dX, X6 X6 30dX, 5' series 530d 155kW, X6 X6 40dX, 5' series 535d and 3' series 330d. Documented fitment covers model years 1998-2023, 1997-2023 and 2004-2017. Early and late builds of the same engine can use different revisions, so identification from the original component is essential.
Specifications: 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. Further specification details: valve train 24 Valves. Manufacturing is carried out under IATF 16949 ISO9001 quality systems.
OEM / Reference Numbers: OEM and cross-reference numbers covered by this listing are 11217809117, 11218511654 and 11217799970. Cross-check these numbers with the casting or part marks on the original component to confirm the correct variant before purchase.
Applications: Applications include complete engine rebuilds, preventative bottom-end renewal and repair of units damaged by lubrication failure. It suits passenger cars, light commercial vehicles and, where listed, industrial or agricultural machinery powered by the relevant engine.
Benefits / Replacement Information: A new crankshaft removes the vibration, knocking and low oil pressure associated with worn journals or a bent shaft. Because the shaft is supplied in standard size and ready to fit, it avoids the lead time and expense of re-grinding an original unit. A new component avoids the lead time and uncertainty of sourcing and reconditioning a used original part.
Installation or Fitment Notes: Check the part number, journal dimensions and cylinder block line bore before assembly begins. Install with new bearings, confirm oil clearance using plastigauge, and tighten the main and rod caps to factory torque and sequence. Installation should be carried out by a qualified technician using the vehicle manufacturer's procedures and torque specifications.
