The Chelsea 680XRAHX-P3XD is an 8-bolt Power Take-Off from the Chelsea 680 Series, engineered for medium- to heavy-duty manual transmission applications on Eaton Fuller, Volvo/Mack, Daimler/Detroit, and other compatible transmissions. The cast iron housing pairs with tapered cone bearings on the output shaft for a high torque rating and extended service life. The 680 Series supports SAE A, SAE B, and ISO 7652 pump flange outputs as well as driveline output, with four internal speed ratios and a space-saving air shift cover that maximizes clearance under the vehicle. The series is rated for intermittent torque of 375 lb-ft (508 Nm), with continuous operation available at a 30% de-rating. Applications include aerial, dump truck, refuse, snow and ice removal, fire and rescue, service trucks, and pneumatic blowers.
