HX40W turbocharger with OEM number 3783602 is a Holset original pneumatic wastegate turbocharger exclusively matched for Dongfeng Cummins DCEC 8.9L 6LTAA/ISL series diesel engines (L340/L360 horsepower grade). It compresses intake air to raise cylinder air density, optimize fuel combustion efficiency, lift engine power output, reduce fuel consumption and exhaust black smoke emissions, serving as official OEM aftermarket replacement spare part for domestic commercial vehicles and engineering equipment maintenance.

Overview

Product Details

Manufactured strictly following Holset and Cummins original drawings, dimensional tolerance and process standards, this turbo boasts precise fitment for DCEC 8.9L L-series engines. It can thoroughly resolve common vehicle failures including insufficient climbing power, heavy black smoke during acceleration, abnormal engine oil consumption and turbo lag triggered by aging or damaged turbo assemblies.The rotor assembly undergoes professional high-speed dynamic balance calibration; all finished products pass air tightness testing, boost pressure calibration and comprehensive appearance inspection before delivery, capable of stable continuous operation under long-term heavy load, frequent start-stop and high exhaust temperature harsh working conditions.Interchangeable OEM No.: 3783602、4044691、4047354、4051032

Product Advantages

High-strength Material & Reliable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel-based alloy material, outstanding thermal fatigue resistance, fully adapted to the high exhaust temperature working environment of 8.9L large-displacement heavy-duty diesel engines
Floating oil lubrication bearing system ensures smooth rotor rotation, effectively suppresses oil leakage risk, withstands long-duration heavy load impact and frequent urban start-stop operation
External pneumatic diaphragm wastegate structure, accurately regulates intake boost pressure in real time, avoids engine damage caused by overboost, and delivers sensitive low-speed torque response

OEM Standard Precision Manufacturing

Overall outline, mounting hole layout and boost pressure calibration parameters are completely consistent with original factory components, supporting direct bolt-on installation without any modification
High-precision dynamic balanced rotor lowers operating vibration and noise, effectively extends the overall service life of the turbocharger
Multi-channel air tightness detection eliminates oil seepage, compressor surge and abnormal exhaust noise issues
