7C-7580 7C7580 Turbocharger for Caterpillar 3306 3306B Diesel Engine S4DS011 Turbo Assembly Excavator Parts

The 7C-7580 Diesel Engine Turbocharger Assembly is a replacement turbocharging component designed for compatible Caterpillar 3306 and 3306B diesel engines used in excavators, construction machinery, and industrial equipment.

Also known as a Diesel Engine Turbocharger, Exhaust Gas Turbocharger, S4DS011 Turbo, or Engine Turbo Assembly, this component is designed to increase the amount of compressed air supplied to the engine intake system.

The turbocharger uses exhaust gas energy to drive a turbine wheel, which powers the compressor wheel and delivers compressed air into the engine.

By increasing the available intake air, a correctly matched turbocharger helps the diesel engine achieve its intended power output, combustion performance, and operating efficiency.

The 7C-7580 turbocharger features a silver-gray metallic compressor housing, heavy-duty turbine housing, machined connection flanges, central bearing housing, and metallic fastening clamps.

The pictured turbocharger includes a large compressor housing, a cast-metal exhaust turbine section, and a twin-port exhaust connection flange.

Its mechanical construction is intended for installation in compatible 3306 series diesel engine turbocharging systems.

JISION supplies diesel engine turbochargers, fuel injection components, engine overhaul parts, hydraulic components, and replacement parts for excavators and heavy construction machinery.
