The Chelsea 680XFAHX-A3GQ is an 8-bolt Power Take-Off (PTO) from the Chelsea 680 Series, designed for medium to heavy-duty manual transmission applications. The 680 Series is built around a cast iron housing with tapered cone bearings on the output shaft, giving the series its high torque rating and extended service life. This series targets higher-torque work such as pneumatic blowers, and the space-saving air shift cover maximizes clearance under the truck. The 680 Series is well suited to Eaton Fuller transmissions and includes a deep-mount housing option for Mack applications. Call us to confirm proper fit for your specific transmission and pump configuration.
