Description
The Chelsea 680 Series Power Take-Off, part number 680XSAHX-A5AF or 680XSAHXA5AF, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. It uses a wire/cable mechanical shift and delivers a 1-1/4″ round output shaft with key. Intermittent torque is rated at 375 lb-ft (508 Nm) – check application pages for actual torque ratings specific to your setup. Shaft power output runs 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. A deep-mount housing option accommodates Mack transmission applications, and the cast iron housing with tapered cone bearings on the output shaft suits high-torque demands like pneumatic blowers.
