The Construction machinery turbocharger by Shengkunda, featuring models such as the HX25W (Part Nos. 3599355 and 4038790), is a precision-manufactured forced induction unit designed for high mechanical efficiency. As a high-durability Construction Machinery Diesel Engine Turbocharger, it is fully compatible with C15 and 3406E engines, as well as 140H graders.
By utilizing a K18 heat-resistant alloy turbine wheel and a high-silicon molybdenum housing, this Turbocharger for Construction Equipment maintains its structural integrity under extreme thermal stress. The standardized bolt-on interface allows for a direct-fit replacement without manifold modifications, restoring original engine performance. Every piece of our Turbochargers for Construction Equipment is high-speed balanced to eliminate vibration, ensuring consistent air intake and reliability for heavy-duty digging and lifting tasks in demanding environments.

The turbocharger features a reinforced housing and internal components specifically designed to resist the high-vibration and dust-heavy environments of construction sites.
Every internal rotor assembly undergoes high-speed balancing to minimize shaft vibration, which reduces wear on engine bearings and prevents premature failure during continuous operation.
The turbine wheel and housing are crafted from high-grade alloys that maintain structural integrity and prevent cracking under the intense heat of heavy-duty diesel cycles.
By maximizing air compression, the unit ensures a dense oxygen supply to the combustion chamber, allowing for more efficient fuel burning and sustained torque delivery during high-load tasks.
Manufactured to exact technical specifications for models like the 127-5151 and 0R-7053, ensuring seamless integration with existing engine oil and cooling lines.
Our Construction machinery turbocharger is specifically tailored for excavators, graders, and heavy loaders. It is a critical component for machinery operating in mining, road construction, and large-scale infrastructure projects where consistent engine output is required for hydraulic power and traction.
