The Chelsea 680 Series Power Take-Off, part number 680XSAHX-V3AF or 680XSAHXV3AF, is a medium- to heavy-duty 8-bolt PTO built around a cast iron housing with tapered cone bearings on both the output shaft and input shaft. Those tapered bearings handle heavier radial loads than needle bearings, giving the unit its higher torque rating. Intermittent torque is rated at 375 lb-ft (508 Nm), verify the exact figure against the application pages for your installation. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key suits pneumatic blower drives and similar high-torque vocational work. The 680 covers Eaton/Fuller and Volvo/Mack transmissions with an 8-bolt aperture, and the deep-mount housing option accommodates Mack applications. Available from Pro Gear and Transmission, call us to confirm proper fit for your transmission and application.
