Overview

Product Details

This product is produced in strict accordance with Holset original factory dimensional standards and process specifications, with precise assembly tolerance matching for Cummins 6CT series engines. It can effectively solve common vehicle faults including insufficient power, excessive black smoke emission, abnormal engine oil consumption and turbo lag caused by aging or damaged turbochargers.The rotor assembly is calibrated by professional high-speed dynamic balance; all finished products pass air tightness test, boost pressure calibration and appearance inspection before delivery, which can maintain stable operation under long-term heavy load and high exhaust temperature working conditions.Interchangeable OEM No.: 3781769、3780245、3787027

Product Advantages

High-strength Material & Reliable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant alloy materials, excellent thermal fatigue resistance, suitable for the high-temperature exhaust working environment of 8.3L heavy-duty diesel engines
Oil-lubricated floating bearing system ensures smooth rotor rotation, effectively reduces oil leakage risk, and adapts to frequent start-stop and long-time heavy load operation
External mechanical diaphragm wastegate structure, stably adjusts boost pressure, prevents engine damage caused by overboost, with stable low-speed torque response

OEM Standard Precision Manufacturing

Overall outline, installation hole positions and boost pressure parameters are completely consistent with original parts, supporting direct bolt-on installation without modification
Dynamically balanced rotor reduces vibration and running noise, prolonging the overall service life of the turbocharger
Strict air tightness inspection eliminates oil leakage, compressor surge and abnormal exhaust noise
