The HX40W pneumatic wastegate turbocharger with OEM number 3783607 is customized by Holset exclusively for DCEC Dongfeng Cummins 8.9L L-series diesel engines rated at 340HP and 360HP. It raises cylinder air density by compressing intake air, optimizes fuel combustion efficiency, boosts engine power output, cuts fuel consumption and black smoke emission, serving as the official standard aftermarket replacement part for maintenance of domestic commercial vehicles and construction machinery.

Overview

Product Details

Manufactured strictly in accordance with Holset and Cummins original drawings, dimensional tolerances and production procedures, this turbo features identical overall structure, mounting dimensions and boost calibration parameters as serial counterparts including 3783602, 3783603, 3783604 and 3783605, enabling mutual interchangeability. It effectively fixes common vehicle faults caused by aging or damaged turbochargers, such as insufficient climbing power, heavy black smoke during acceleration, abnormal engine oil consumption and turbo lag.The rotor assembly undergoes professional high-speed dynamic balance calibration. All finished products pass air tightness inspection, boost pressure calibration and comprehensive appearance quality check before delivery, delivering stable continuous performance under harsh working conditions including long-term heavy load, frequent start-stop and high exhaust temperature.Interchangeable OEM No.: 3783607, 3783602, 3783603, 3783604, 3783605, 4045069, 4048335

Product Advantages

High-strength Material & Stable Structure

Turbine wheel and compressor wheel are made of high-temperature resistant nickel-based alloy with excellent thermal fatigue resistance, perfectly fitting the high exhaust temperature working environment of 8.9L large-displacement heavy-duty diesel engines
Floating oil-lubricated bearing system ensures smooth rotor rotation, greatly reduces oil leakage risks, and withstands long-time heavy load impact and frequent urban start-stop cycles
External pneumatic diaphragm wastegate regulates intake boost pressure accurately in real time to prevent engine damage from overboost and deliver responsive low-speed torque

OEM-standard Precision Manufacturing

Overall profile, mounting hole layout and boost parameters are fully consistent with original factory components, supporting direct bolt-on installation without any modification
High-precision dynamically balanced rotor lowers operational vibration and noise and extends the overall service life of the turbocharger
Multiple air tightness testing procedures eliminate oil seepage, surge and abnormal exhaust noise issues
