HX40W pneumatic wastegate turbocharger with OEM number 3783605 is developed by Holset exclusively for Dongfeng Cummins DCEC 8.9L L-series diesel engines with 340HP and 360HP power ratings. It compresses intake air to increase cylinder air density, optimize fuel combustion efficiency, boost engine power output, reduce fuel consumption and exhaust black smoke emissions, serving as the official standard aftermarket replacement spare part for domestic commercial vehicles and engineering machinery maintenance.

Overview

Product Details

Manufactured strictly following Holset and Cummins original drawings, dimensional tolerance standards and production processes, this turbo shares identical overall structure, mounting dimensions and boost pressure calibration parameters with serial interchangeable part numbers of the same series, and can be mutually replaced for DCEC L-series 8.9L engines. It effectively solves typical vehicle faults including insufficient climbing power, heavy black smoke during acceleration, abnormal engine oil consumption and turbo lag caused by aging or damaged turbo assemblies.The rotor assembly undergoes professional high-speed dynamic balance calibration; all finished products pass air tightness inspection, boost pressure testing and comprehensive appearance quality check 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.: 3783605、3783602、3783603、3783604、4045069、4048335

Product Advantages

High-strength Material & Reliable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel-based alloy materials, with outstanding thermal fatigue resistance, perfectly adapting to the high exhaust temperature operating environment of 8.9L large-displacement heavy-duty diesel engines
Floating oil lubrication bearing system ensures smooth rotor rotation, effectively lowers oil leakage risks, and withstands long-time heavy load impact and frequent urban start-stop cycles
External pneumatic diaphragm wastegate structure precisely regulates intake boost pressure in real time, prevents engine damage caused by overboost, and delivers sensitive low-speed torque response

OEM Standard Precision Manufacturing

Overall outline, mounting hole layout and boost pressure parameters are fully consistent with original factory components, supporting direct bolt-on installation without any secondary modification
High-precision dynamically balanced rotor reduces running vibration and noise, extending the overall service life of the turbocharger
Multi-channel air tightness testing eliminates oil seepage, compressor surge and abnormal exhaust noise failures
