Turbocharger CHRA For Swaraj Mazda TR55 SML Truck Bus 3.5L CNG 115529020733 LP5513700

Premium Turbocharger CHRA Cartridge for Swaraj Mazda / SML Isuzu 3.5L CNG Commercial Engines | TEL 115529020733 / LP5513700

Restore steady manifold boost pressure, eliminate engine sluggishness under heavy payloads, and prevent oil leakage into the air intake system with this premium Turbocharger CHRA (Center Housing Rotating Assembly) Cartridge. Specifically engineered to withstand the elevated exhaust gas temperatures (EGTs) and continuous thermal loads generated by compressed natural gas (CNG) commercial powertrains, this high-precision core cartridge replaces worn internal rotating elements—including the turbine shaft, compressor impeller, bronze journal bearings, and oil seal rings—without requiring the expense of buying complete replacement outer housings.

Manufactured under premium TEL (Turbo Energy Limited) specifications, this heavy-duty core cartridge matches factory production part tracking reference 115529020733 (alongside related series references like 104529021717) and SML Isuzu genuine equipment tracking number LP5513700 (and related casting reference LP7013700). Installing a dynamic-balanced CHRA core cartridge allows commercial transport fleets, workshops, and mechanics to execute a full factory-spec overhaul while preserving the intact, expensive cast-iron turbine and aluminum compressor outer housings.
