One New Aftermarket Replacement Impeller-Converter for Caterpillar (Cat) Track-Type Tractors and Pipelayers
This aftermarket replacement torque converter impeller (Impeller-Converter) is a core drivetrain component located inside the torque converter assembly. The impeller is the pump element of the torque converter, driven by the engine to circulate hydraulic fluid and multiply torque before transferring power to the transmission. Replacing a worn or damaged impeller restores proper torque multiplication and drivetrain efficiency on Caterpillar (Cat) dozers and pipelayers.
