MTU Turbocharger Components

MTU turbochargers are precision-rotating assemblies operating at speeds exceeding 100,000 RPM with exhaust gas inlet temperatures beyond 700 degrees Celsius. The turbine wheel, compressor wheel, bearing housing, and sealing rings form a balanced system where any component wear — even at the micron level — produces vibration, oil leakage, or efficiency loss that cascades into engine performance degradation.

Our turbocharger parts catalog covers the complete rotating assembly: turbine wheels (5110804420, 5110800220, 5110800420), compressor wheels (5090251301), bearing housings (5110803201), piston ring seals (5110850060, 5120850560), heat shields (5110812603, 5110820226), and diffusers (5361420025). We verify each part number against your turbocharger nameplate — not just the engine serial — because turbocharger variants within the same engine series can differ by application, power rating, and emissions certification.

Common failure modes include foreign-object damage to turbine blades from intake debris or exhaust manifold fragments, bearing housing bore wear causing radial play and oil leakage into the exhaust stream, and heat shield cracking from thermal cycling on engines with frequent start-stop duty cycles. We quote new OEM, OEM-alternative, and remanufactured options with transparent lead times.
