The Chelsea 680XHAHX-V3XY or 680XHAHXV3XY is a 680 Series Power Take-Off built for medium- to heavy-duty manual transmission applications with an 8-bolt PTO aperture. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft, making it a fit for higher-torque applications such as pneumatic blowers, dump trucks, aerial units, and refuse equipment. The series covers Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other transmission manufacturers, and includes a deep mount housing option for Mack applications. The space-saving air shift cover maximizes clearance under the truck. Call us to confirm proper fit for your specific transmission and application.
