ASA Engine Equipments supplies premium EMD Turbocharger Parts for EMD 645, 710, and older 567 series engines to customers across USA, Canada, Australia, Bangladesh, Germany, France, UK, Italy, Romania, Austria, Turkey, Mexico, Mozambique, Sri Lanka, Senegal, and Republic of Liana.
🔧 What is an EMD Turbocharger?
An EMD turbocharger is a high-performance air-boosting system designed to increase engine efficiency by delivering higher air pressure for combustion. It improves power output, reduces emissions, and ensures stable operation under heavy load.
Turbocharger increases air density
Enhances fuel burn efficiency
Improves locomotive pulling performance
Reduces black smoke and fuel wastage
The turbo system is a critical part of all EMD 645 & 710 engines, used worldwide for freight, passenger, and marine operations.
🔩 Major EMD Turbocharger Parts We Supply
Below are major turbo components with full descriptions:
- Turbocharger Rotor Assembly
The rotor is the heart of the turbocharger, responsible for converting exhaust gas energy into rotational speed. Our rotors are manufactured using high-grade heat-resistant alloys to withstand extreme operational temperatures.
Details:
Precision-balanced for smooth rotation
Provides stable boost pressure
Reduces vibration and turbo lag
Compatible with EMD 645 & 710 models
- Turbo Compressor Wheel (Impeller)
The compressor wheel delivers compressed air to the intake manifold. ASA supplies CNC-machined impellers for maximum airflow and efficiency.
Expanded Explanation:
Lightweight design ensures faster spool-up
Resistant to deformation under heat
Enhances horsepower and torque
Supports continuous high-speed rotations
- Turbocharger Diffuser
A diffuser helps stabilize airflow and pressure. We supply steel and alloy diffusers for all major turbocharger versions.
Benefits:
Smooth transition of compressed air
Reduces pressure shock inside the turbo
Maintains consistent air delivery
- Nozzle Ring Assembly
Nozzle rings direct exhaust gas flow towards the turbine wheel. Our rings are engineered for optimal heat endurance.
Key Features:
Provides uniform gas distribution
Increases turbine efficiency
Minimizes energy loss
- Turbo Journal Bearings
Journal bearings stabilize the rotor and reduce friction. Our bearings are made from high-strength bronze alloys.
Details:
Enhances rotor life
Supports high-RPM performance
Reduces wear & operational noise
- Turbocharger Blower Housing
The blower housing encloses the turbocharger components. Made from strong cast iron, it ensures structural safety.
Benefits:
High thermal resistance
Prevents external damage
Maintains optimal airflow paths
- EMD Turbocharger Oil Pump
The turbo oil pump ensures lubrication for bearings and moving components.
Important Points:
Reduces friction
Prevents overheating
Increases turbo lifespan

🛠 Installation Tips for EMD Turbocharger Parts
- Verify Rotor and Bearing Alignment
Misalignment can cause vibration and premature wear. Manual rotation should feel smooth without resistance.
- Ensure Proper Lubrication Before Starting
Dry turbo starts are the #1 cause of failure. Always pre-lubricate.
- Check for Air Leakages
Loose clamps or cracked pipes reduce boost pressure and engine power.
- Follow OEM Torque Specifications
Over-tightening or loose tightening affects performance and safety.
🧰 Maintenance Tips for Long Turbocharger Life
- Maintain Clean Oil System
Dirty oil damages bearings. Replace oil regularly.
- Monitor Boost Pressure Levels
Sudden drop = leak or damaged rotor
Sudden rise = blockage or over-boost
- Prevent Overheating
Allow engine to idle before shutdown to cool the turbo.
- Regular Inspection of Blades
Bent or chipped blades reduce airflow efficiency.
❗ Common Turbocharger Problems & Solutions
Problem 1: Excessive Smoke
Cause: Weak turbo pressure
Solution: Check for leaks or rotor damage
Problem 2: High Fuel Consumption
Cause: Low air boost
Solution: Inspect diffuser and impeller
Problem 3: Loud Whining Noise
Cause: Bearing failure
Solution: Replace journal bearings immediately
Problem 4: Low Engine Power
Cause: Wastegate stuck or air blockage
Solution: Clean and inspect air pathways
