One-stop Shopping Forged Alloy Steel Crankshaft 11217803479 for BMW N47D20 Diesel Engine
This heavy-duty forged alloy steel crankshaft with OE number 11217803479 is the core rotary power component for BMW N47D20 2.0L diesel engine. It is a critical engine overhaul part, ideal for mixed one-stop bulk ordering with bearing shells, piston kits, timing assemblies and full engine repair kits, widely favored by BMW specialized repair shops and cross-border auto parts wholesalers.
Core Selling Points
High-load diesel overhaul core part for integrated one-stop procurement
Crankshafts are high-mileage failure-prone components for N47D20 diesel engines. Original crankshafts suffer journal scoring, fatigue cracks, bending deformation and timing gear tooth abrasion under long-term high torque output, frequent short trips and bumpy road vibration. Damaged crankshafts trigger persistent loud knocking from the lower engine block, severe vehicle shaking, constant low oil pressure warning, rapid bearing shell ablation and hidden risk of engine seizure. Repair garages and overseas exporters usually combine this crankshaft with a full set of internal engine parts in one order to cut procurement and logistics costs, with stable continuous bulk orders and favorable profit margins for dealers.
100% OE precise fit, direct assembly without modification
Manufactured strictly following BMW OEM standards: overall forging length, main journal and connecting rod journal diameters, internal lubricating oil passage layout, front timing gear tooth profile, rear sealing flange bolt hole layout and factory dynamic balance data fully match genuine 11217803479. Interchange OE reference codes are available for cross matching. No cutting, grinding or straightening correction is required during engine rebuilding, perfectly fitted to N47D20 cylinder block and greatly shortening labor hours for engine disassembly and overhaul.
Compatible Vehicle & Engine Range
- Core matching engine: BMW N47D20 2.0L four-cylinder diesel engine
- Applicable models equipped with N47D20 power unit:
1 Series F20/F21, 3 Series F30/F31/F34, 5 Series F10/F11, X1 E84/F48, X3 F25, X5 E70
Reinforced heavy-duty wear-resistant forged structure
- One-piece high-strength alloy steel forging with overall quenching & tempering heat treatment, excellent anti-bending and anti-fatigue performance to withstand long-duration diesel high torque
- Journal surface high-frequency quenching nitriding treatment, high surface hardness to effectively avoid journal scratches and eccentric wear of bearing shells
- Complete precision internal oil galleries, evenly supply lubricating oil to all journals to eliminate dry friction ablation risk
- Integrated front timing gear with precise tooth profile, stable power transmission without tooth stripping or timing deviation faults
- Mirror-polished rear sealing flange to reduce rear crankshaft oil seal leakage; factory pre-calibrated dynamic balance to suppress high-speed engine vibration
Restore stable low-speed diesel torque performance
Converts piston linear reciprocating motion into rotational power output, maintaining steady low-speed pulling torque during acceleration, climbing and full-load driving. Eliminates abnormal knocking and vehicle vibration caused by defective original crankshaft, stabilizes engine lubrication pressure, reduces abrasion of cylinder liners and pistons, and fully recovers the original power and fuel economy of N47D20 diesel engine.
Fully resolve typical crankshaft failure faults
- Continuous loud knocking impact noise from engine crankcase after startup
- Obvious vehicle shaking during acceleration and uphill driving
- Dashboard oil pressure warning light stays on persistently
- Scratched journal surfaces accelerate wear of main and connecting rod bearing shells
- Fatigue cracks on counterweights create hidden risks of crankshaft fracture and engine stall
- Worn timing gear teeth trigger ECU engine timing malfunction fault codes
Rigorous multi-stage factory testing & sufficient spot stock
Every crankshaft passes dynamic balance calibration, salt spray anti-corrosion test, torsion fatigue durability test, journal hardness inspection and oil passage pressure tightness test before delivery, compliant with IATF 16949 international automotive quality standards. Mass ready stock supports mixed one-stop bulk procurement with crankshaft bearing shells, piston assemblies, timing chains, oil pumps and complete N47D20 engine overhaul kits. Custom neutral packaging and private label OEM customization services are available for cross-border wholesale buyers.
