Turbocharger CHRA For Bharat Benz 1217 914 1617 Truck 3.9L 808472-0001 A4000900180

Turbocharger CHRA Core Assembly for BharatBenz 1217, 914, 1617 MD Trucks | 3.9L Diesel | 808472-0001 / A4000900180 Restore high-load torque, eliminate oil leakage into the intercooler, and recover factory boost pressure with this heavy-duty Turbocharger CHRA (Center Housing Rotating Assembly / Core Assembly). Engineed as a direct-replacement cartridge for commercial haulers running the 3.9L 4D34i / 4D37 turbocharged diesel engine, this balanced CHRA replaces worn internal components—including the turbine shaft, compressor wheel, journal bearings, thrust collar, and oil seals—without requiring the expense of a complete turbocharger housing replacement. Designed to withstand continuous heavy hauling, steep gradient climbs, and extended idling, this dynamic-balanced core assembly resolves common symptoms like excessive exhaust smoke, boost lag, whistling noise, and shaft play. Detailed Vehicle & Engine Compatibility This CHRA cartridge is precision-machined for seamless fitment within the original Garrett turbocharger housing on BharatBenz Medium-Duty (MD) commercial platforms: Vehicle Models: BharatBenz 1217, BharatBenz 914, BharatBenz 1617 MD Trucks. Engine Displacement: 3.9L Turbocharged Commercial Diesel Engine. Primary Application: Freight transport, medium-duty hauling, and regional logistics fleets. Critical Part Number & Cross-Reference Mapping Garrett Turbo Part Numbers: 808472-0001 | 808472-5001S | 808472-1 Daimler / BharatBenz OEM Number: A4000900180 Interchange / Related Part Numbers: 808472-0003 | A4000900480 Key Technical Specifications & Engineering Features High-Speed VSR Dynamic Balancing: Factory-balanced on high-speed VSR machines to eliminate micro-vibrations, ensuring smooth shaft rotation up to 150,000+ RPM and preventing premature bearing wear. Precision Journal & Thrust Bearings: Cast bronze/copper-alloy floating journal bearings withstand harsh thermal loads and heavy axial thrust under high manifold pressures. Heat-Resistant Inconel Turbine Shaft: High-grade Inconel alloy turbine wheel/shaft handles intense exhaust temperatures during sustained heavy-load highway driving. High-Flow Billet/Cast Compressor Wheel: Maintains exact aerodynamic profile for rapid air compression and minimal turbo lag. Advanced Oil Sealing System: Heavy-duty piston ring seals prevent oil blow-by into the compressor and turbine housings, protecting the intercooler and engine intake manifold. Commercial Fleet & Workshop Advantages Cost-Effective Overhaul: Replacing only the CHRA cartridge delivers factory-level turbo performance at a fraction of the cost of a complete unit. Plug-and-Play Rebuild: Drops directly into the existing OEM turbine and compressor housings without requiring machining or custom modifications. Restored Fuel Efficiency & Power: Clean boost pressure ensures complete air-fuel combustion, cutting down fuel consumption and reducing soot output during steep climbs.
