2191909 Cartridge Fits Caterpillar Models

One New Aftermarket Replacement Turbocharger Cartridge for Caterpillar (Cat) 3306 and 3306B Engines

This aftermarket replacement turbocharger cartridge (CHRA - center housing rotating assembly) fits the Caterpillar 3306 and 3306B engine as used across a wide range of Cat motor graders, track-type tractors, and excavators. The cartridge is the internal rotating core of the turbocharger assembly, replacing OEM part 219-1909 and fitting within the 219-1911 Turbocharger GP assembly. Replacing the cartridge restores turbocharger function - boosting intake air pressure to optimize fuel combustion and engine power output - without requiring replacement of the full turbo housing.
