HE400WG wastegate turbocharger is developed by Holset for medium-to-large displacement DCEC Cummins ISL heavy-duty diesel engines. It compresses intake air to raise cylinder air density, improves fuel combustion efficiency and low-speed torque output, lowers fuel consumption and exhaust emissions, conforming to Euro IV, Euro V and China National VI emission standards, serving as genuine aftermarket replacement spare parts for commercial vehicles and construction equipment.

Overview

Product Details

Manufactured strictly in accordance with Holset and Cummins original drawings, dimensional tolerances and production specifications, Assy No.3789026 shares identical structural layout, mounting dimensions and boost calibration parameters with all interchange part numbers, supporting direct mutual replacement. It thoroughly resolves common faults caused by turbo aging and damage: insufficient climbing power, excessive exhaust smoke, abnormal engine oil consumption and obvious turbo lag.The rotor assembly undergoes high-precision high-speed dynamic balance calibration; all finished products pass air tightness test, boost pressure calibration and comprehensive appearance inspection before delivery, capable of stable long-term operation under harsh working conditions including continuous heavy load, frequent start-stop and high exhaust temperature.Interchangeable OEM No.: 3789026, 3785222, 3785228, 3788085, 3789024, 4037541, 4046098, 3783430, 3785224, 3785225

Product Advantages

High-strength Material & Stable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel-based alloy with superior thermal fatigue resistance, adapting to the high exhaust temperature operating environment of large-displacement heavy-duty diesel engines
Floating oil film lubrication bearing system ensures smooth rotor rotation, effectively prevents oil leakage, and withstands long-time heavy load impact and frequent urban start-stop cycles
External pneumatic wastegate precisely regulates intake boost pressure in real time, avoids engine damage from overboost, and delivers responsive low-speed power

OEM-standard Precision Machining

Overall outline, mounting hole layout and boost parameters are fully consistent with original factory components, enabling bolt-on direct installation without any modification
High-precision dynamically balanced rotor reduces operational vibration and noise, greatly extending the overall service life of the turbocharger
Multiple air tightness inspection procedures eliminate oil seepage, compressor surge and abnormal exhaust noise
