Turbocharger For Cummins Engine Tata Signa HE250WG 5564133 5564135 5564136 Holset

Complete Turbocharger Assembly for TATA Signa HE250WG | Holset 5564133 / 5564135 / 5564136 / 5503251

Restore heavy-duty haulage torque, eliminate boost pressure drops under full freight loads, and prevent excessive exhaust smoking with this high-performance Complete Turbocharger Assembly. Specially engineered to handle the continuous duty cycles, intense under-hood thermal stress, and high exhaust backpressures of modern commercial transport platforms, this complete unit replaces failing forced-induction systems suffering from turbine housing thermal stress cracks, journal bearing play, oil seal leakage, or wastegate actuator failure.

Belonging to the heavy-duty Holset HE250WG Wastegate Turbocharger platform, this complete assembly directly corresponds to Holset / Cummins Turbo Technologies production tracking references 5564133, 5564135, and 5564136 (including related engineering references such as 5503251 and 5503252). It is custom-calibrated as a direct-fit replacement for TATA Motors heavy commercial vehicle platforms, restoring clean fuel combustion, optimizing engine efficiency, and protecting downstream emissions controls.

Detailed Commercial Vehicle & Engine Application Mapping

This heavy-duty commercial turbocharger is engineered to integrate seamlessly into TATA Motors' heavy haulage and construction truck platforms:

Key Technical Specifications & Features

• Heavy-Duty High-Nickel Turbine Casing: Cast from thermal-resistant ductile iron to prevent structural cracking, warping, or exhaust gas leaks under continuous full-load haulage and steep incline pulls.

• Integrated Wastegate Actuator Mechanism: Factory-calibrated pneumatic wastegate actuator delivers precise boost modulation across varying engine load conditions, preventing over-boost stress while ensuring sharp low-RPM spool-up.

• VSR Ultra-High-Speed Dynamic Balancing: Core rotating assembly undergoes precision dynamic balancing on computerized Vibration Sorting Rigs (VSR) at full operational RPMs to eliminate micro-vibrations, ensuring quiet operation and extending journal bearing lifespan.

• Heavy-Duty Journal & Thrust Bearings: Floating copper-alloy journal bearings handle intense backpressures and heavy axial loads during prolonged long-haul transport.

• Advanced Internal Fluid Seals: Heavy-duty piston ring seals prevent motor oil from passing into the compressor piping or exhaust stack, preserving clean intake charge air and reducing engine oil consumption.
