125-1128 1251128 Turbocharger for 3116 Diesel Engine E320B 320B Excavator Turbo Assembly

The 125-1128 Turbocharger is a replacement diesel engine turbocharger assembly designed for compatible 3116 diesel engine applications, including selected E320B and 320B excavator configurations.

Also known as an Engine Turbocharger, Diesel Turbo Assembly, Exhaust Gas Turbocharger, or Excavator Engine Turbo, this component is designed to increase the amount of compressed air supplied to the engine intake system.

As an important component of a turbocharged diesel engine, the turbocharger uses exhaust gas energy to drive a turbine wheel, which powers a compressor wheel to deliver compressed air into the engine.

By increasing the available intake air, a properly functioning turbocharger helps the engine achieve its designed power output, combustion performance, and operating efficiency.

The 125-1128 turbocharger features a silver-colored compressor housing, metallic turbine housing, precision rotating assembly, machined intake connection, exhaust connection flange, and integrated oil connection interfaces.

Its compact assembly is intended for installation in compatible 3116 diesel engine turbocharging systems.

JISION supplies diesel engine turbochargers, fuel injection components, engine overhaul parts, hydraulic components, and construction machinery replacement parts to equipment owners, repair workshops, construction contractors, and international spare parts distributors.
