Genuine turbine assembly-195-13-71510

Core Features

Energy Recovery: Absorbs the kinetic and thermal energy of engine exhaust, driving the turbine to rotate at high speed and converting exhaust gas energy into mechanical energy.

Turbocharging: Drives the coaxial compressor impeller to rotate, compressing the intake air, increasing intake pressure (≤2.2 bar) and density, improving engine power (by approximately 30%) and fuel efficiency.

Speed Matching: Adaptively adjusts the engine speed according to exhaust flow and pressure to match the intake air requirements under different engine operating conditions.

Sealing and Heat Insulation: Prevents exhaust gas leakage through seals, and a heat shield blocks high temperatures, protecting the turbocharger intermediate body and bearings.

Stable Support: Floating bearings and thrust bearings support the turbine shaft, ensuring high-speed rotational stability and reducing vibration and wear.

Product Superiority

Original Equipment Manufacturer Precise Fit: The turbine impeller size, shaft diameter, and bearing positions are fully compatible with the SAA6D170E-5 turbocharger/exhaust system, allowing for direct replacement without any repairs.

High Temperature and Fatigue Resistance: The IN713C nickel-based alloy impeller can withstand temperatures up to 850℃, resisting thermal shock and creep, with a fatigue life ≥15,000 hours.

High-Efficiency Energy Conversion: The turbine impeller's efficient aerodynamic design achieves exhaust gas energy utilization ≥75%, providing fast boost response and reducing turbo lag.

High-Speed, Stable, and Reliable: The combination of floating bearings and thrust bearings results in radial runout ≤0.03 mm, ensuring no abnormal vibration during high-speed rotation and supporting a maximum speed of 120,000 rpm.

Excellent Sealing and Leak Prevention: The metal sealing ring and heat shield design prevents exhaust gas leakage and heat dissipation, protecting surrounding components and reducing oil consumption.

Installation and Maintenance Points

Before installation, clean the turbine assembly, exhaust manifold interface, and turbocharger intermediate body. Inspect the impeller for cracks, shaft for bending, and bearings for sticking.

Install according to the original factory markings, ensuring the turbine shaft and compressor shaft are coaxial. Tighten to the specified torque (exhaust manifold bolts 80–90 N·m).

After installation, check that the turbine rotates smoothly without sticking or rotor rubbing, the boost pressure is within the range of 1.8–2.2 bar, and there is no abnormal exhaust noise.

Every 2000 hours, check the turbine impeller for carbon buildup, shaft wear, and seal condition. Clean if carbon buildup is greater than 0.5 mm, and replace immediately if wear exceeds the limit.

After starting the engine, allow it to idle for 3–5 minutes before loading. Before shutting down, allow it to idle for 2–3 minutes to prevent turbine overheating and damage. Change the engine oil and filter regularly to ensure bearing lubrication.

Fit scenarios and value

Suitable for: High-load conditions such as mine stripping, large-scale earthmoving and transportation, and long-term continuous operation.

Core value: Improves engine power and fuel efficiency, reduces fuel consumption, extends engine life, and reduces downtime during heavy-load operations.
