Turbocharger Assembly 53279880001 (Genuine DEUTZ/MWM Part)

1. Basic Information

• Part Number: 53279880001 (Genuine BorgWarner part number)
• Model: K27 (K27.2 platform)
• Brand: DEUTZ / MWM / BorgWarner (3K)
• Applicable Models:
  
  
  DEUTZ MWM TBG 616/620 gas engines
  
  
  DEUTZ MWM TCG 2016/2020/2032 series (V12/V16/V20)
  
  
  MWM TBD616V8 marine and industrial engines

• Function: Driven by exhaust gas, the turbine drives the compressor to charge intake air. It improves volumetric efficiency, increases power output by 30%–50%, optimizes combustion and cuts fuel consumption and exhaust emissions.
• Matching Parts: Core component of engine intake and exhaust system, matched with intercooler, intake manifold and exhaust manifold.

2. Structure & Materials

Turbine Side (Hot End)

• Turbine Wheel: Nickel-based superalloy, resistant to high temperature over 850℃ and creep deformation.
• Turbine Housing: Ductile iron, high temperature resistance and thermal shock resistance.

Compressor Side (Cold End)

• Compressor Wheel: High-strength cast aluminum, lightweight and designed for high rotating speed.
• Compressor Housing: Aluminum alloy with excellent heat dissipation and light weight.

Central Housing & Bearing System

• Bearing: Full floating bearing design, vibration-resistant and long service life.
• Lubrication: Pressure lubrication via engine oil with dedicated cooling oil passages.
• Sealing: Combined metal and rubber seal to prevent oil leakage and air leakage.

Wastegate

• Built-in pneumatic wastegate actuator to regulate boost pressure and avoid over-speed and over-pressure.

Operating Temperature

• Continuous temperature at turbine side: ≤850℃
• Continuous temperature at compressor side: ≤180℃

• Recommended Products: Only genuine or remanufactured BorgWarner products are acceptable. Ordinary aftermarket products are prohibited to avoid the risk of high-speed failure.

6. Installation & Maintenance Instructions

Pre-installation Inspection

• Check the housing for cracks, turbine and compressor wheels for deformation and scratches. Ensure the bearing rotates smoothly without sticking.
• Keep sealing surfaces intact and clean, and make sure all gaskets are complete.

Mounting Torque

• Turbine inlet flange: 25±3 Nm
• Compressor outlet: 20±2 Nm
• Oil inlet port: 15±2 Nm

Lubrication Requirements

• Pre-fill 50 ml engine oil before installation and rotate the wheel manually to lubricate bearings.
• Run the engine at idle speed for 3–5 minutes after start-up; avoid rapid acceleration.

• Replacement Cycle

  Replace every 20,000 operating hours or 36 months, whichever comes first. Regularly inspect intake/exhaust leakage, oil consumption and boost pressure.
