The Chelsea 680 Series Power Take-Off, part number 680XFAHX-V3GK or 680XFAHXV3GK, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. It features a cast iron housing with tapered cone bearings on the output shaft for high torque capacity, and the input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. Output is via a 1-1/4" round shaft with keyway. The wire/cable mechanical shift cover is space-saving, providing maximum clearance under the truck. Intermittent torque rating for the 680 Series reaches 375 lb-ft (508 Nm) - check application pages for actual torque ratings specific to your installation. Rated output power exceeds 56 HP (51+ kW), with shaft power of 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. A genuine Chelsea part from Pro Gear and Transmission.
