The Chelsea 680 Series Power Take-Off Assembly, part number 680XSAHX-A5XK or 680XSAHXA5XK, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. This unit uses wire/cable mechanical shifting and delivers a 1-1/4" round output shaft with keyway. Intermittent torque rating runs 301-400 lb-ft (check application pages for actual torque ratings). The cast iron housing and tapered cone bearings on the output shaft handle higher-torque work such as pneumatic blowers, dump trucks, refuse bodies, and aerial equipment. A deep-mount housing option accommodates Mack transmission applications specifically. Shaft power output reaches 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. Call us to confirm proper fit for your transmission before ordering.
