The Chelsea 680 Series Power Take-Off Assembly, part number 680GQAHX-A5AF or 680GQAHXA5AF, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller and Volvo/Mack applications. It shifts via wire/cable mechanical actuation and delivers output through a 1-1/4" round shaft with key. Intermittent torque capacity for the 680 Series reaches 375 lb-ft (508 Nm); check application pages for the actual rating specific to your setup. Shaft power output at 1,000 RPM is 71 HP (53 kW), stepping up to 107 HP (80 kW) at 1,500 RPM. The cast iron housing and tapered cone output shaft bearings make it a proven choice for pneumatic blower drives, dump trucks, refuse bodies, and other high-torque vocational work. The deep-mount housing option suits Mack transmission installations. Call us to confirm proper fit for your application.
