One New Aftermarket Replacement Torque Converter Impeller for Caterpillar (Cat) Construction Equipment
This aftermarket replacement torque converter impeller fits Caterpillar (Cat) construction equipment. The impeller is the driving member of the torque converter assembly, spinning with engine speed to pump hydraulic fluid outward toward the turbine blades. This action transfers engine torque to the transmission input shaft, enabling smooth power delivery and torque multiplication during operation of heavy-duty Cat machinery.
About This Part
The torque converter impeller sits inside the converter housing and initiates the torque multiplication process by imparting kinetic energy to the transmission fluid through its curved vanes. Wear or damage to the impeller results in reduced power transfer and sluggish machine response. This aftermarket replacement part is manufactured to fit Caterpillar equipment torque converter assemblies.
Compatible Models
Caterpillar (Cat): Fits Caterpillar models equipped with the compatible torque converter assembly. Verify fitment by cross-referencing OEM part number 1T1494 (also formatted as 1T-1494) with your machine's parts catalog or serial number before ordering.
