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.

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.
