3808712 20R3229 Turbocharger For Caterpillar 374D

Turbine impeller: Made of nickel based high-temperature alloy (Inconel), it can withstand an ultra-high temperature environment of 1050 ℃ and has excellent thermal fatigue resistance. It meets the lifelong maintenance free durability standard and does not require frequent maintenance and replacement.
Turbine casing: Made of heat-resistant stainless steel alloy forging, it has strong resistance to thermal shock and corrosion, avoiding deformation and cracking risks under high temperature conditions from the root, and ensuring long-term stable operation.
Compressor impeller: Made of high-strength forged aluminum alloy, with a lightweight structural design that balances high-speed stability. The aerodynamic efficiency is significantly improved by 15%, helping the engine power output to be more efficient.
Intermediate/Bearing System: High precision floating bearings paired with alloy shells can withstand ultra high speed rotations of over 200000 rpm, with extremely low friction loss and strict vibration control within 0.02mm. The smooth operation is industry-leading.
Sealing component: multi-layer metal composite material with graphite coating process, achieving zero leakage sealing guarantee, eliminating the hidden danger of oil entering the intake system, and effectively extending the overall service life of the engine.

This Turbocharger is Widely used in construction machinery, such as Caterpillar 365C/374D series excavators, large mining loaders, and heavy-duty bulldozers.
