The Chelsea 680 Series Power Take-Off Assembly, part number 680ZQDAX-A5RB or 680ZQDAXA5RB, is built for medium to heavy duty applications requiring an 8-bolt transmission mount. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft, giving it strong load-bearing capability suited to pneumatic blowers and other higher torque vocational work. This unit shifts via wire/cable mechanical actuation and delivers a 1-1/4" round output shaft with key. Intermittent torque is rated at 375 lb-ft (508 Nm); verify the exact rating for your application on the Chelsea application pages. A deep mount housing option covers Mack transmission installations, and the series is also compatible with Eaton/Fuller and Volvo/Mack gearboxes with 8-bolt PTO apertures.
