The Chelsea 680XHAHX-V3RY is an 8-Bolt Power Take-Off from the Chelsea 680 Series, engineered for medium to heavy duty manual transmission applications including Eaton Fuller and Mack transmissions. The 680 Series features a cast iron housing with tapered cone bearings on the output shaft, and the PTO input shaft uses tapered bearings rather than needle bearings for greater load capacity. Output options include SAE A and SAE B pump flanges, ISO 7652 pump flange, and driveline configurations. The series carries an intermittent torque rating in the 301-400 lb-ft range, with continuous operation supported at a 30% de-rating. Shift is via wire/cable or mechanical actuation. The 680 Series was specifically designed for higher torque applications such as pneumatic blowers, and its space-saving air shift cover maximizes clearance under the truck.
