The Chelsea 680GQAHX-P5AF or 680GQAHXP5AF is a medium- to heavy-duty Power Take-Off from the Chelsea 680 Series, designed for manual transmissions with an 8-bolt PTO aperture. The 680 Series uses a cast iron housing with tapered cone bearings on both the input and output shafts for greater load-bearing capability compared to needle-bearing designs. The series carries an intermittent torque rating of up to 375 lb-ft (508 Nm), with continuous operation permitted at a 30% de-rating. Shift options include wire/cable and mechanical actuation. The space-saving air shift cover maximizes clearance under the truck. The 680 Series supports applications such as dump trucks, pneumatic blowers, aerial equipment, and refuse vehicles. Call us to confirm proper fit for your specific transmission and application.
