178-8139: Countershaft

Description: Cat drive train components must endure incredible torque, high impact loads, and frequent direction and gear changes. Cat designs and manufactures its transmissions and final drive components with these demands in mind. The result is a drive train that lasts longer and works harder over the life of the machine. Cat countershafts are used as an intermediary transmitting power from a driving shaft to a driven shaft.
