IHI 114400-3770 RHG6 Turbocharger Assembly

The IHI RHG6 turbocharger (part number 114400-3770) is an exhaust-gas-driven turbocharger designed for Isuzu 6BG1T 6.5-liter inline-six diesel engines. It features a wastegate actuator for boost pressure control and a turbine housing constructed from high-temperature silicon-molybdenum alloy for thermal durability. The compressor wheel utilizes a 6+6 blade configuration. This unit serves as a direct OEM replacement for Hitachi ZAXIS 200, ZX200-3G, ZX200-5G, ZX210, ZX240, ZX250, ZX280, and ZX290 hydraulic excavators, as well as Sumitomo SH200A3 models. Each assembly undergoes 100% balancing testing at high rotational speeds to ensure vibration-free operation and extended bearing life. Cross-reference part numbers include VA570031, VB570031, VC570031, VD570031, and CICZ.
