The Chelsea 680XHAHX-A3XV is an 8-bolt mount power take-off from the Chelsea 680 Series, engineered for medium- to heavy-duty manual transmission applications. The cast iron housing and tapered cone bearings on the output shaft give the 680 Series a strong torque rating suited to demanding jobs such as pneumatic blowers, aerial equipment, and refuse trucks. The series carries an intermittent torque rating of 375 lb-ft (508 Nm) and supports continuous operation with a 30% de-rating. Output options include SAE A and SAE B pump flanges, ISO 7652 pump flange, and driveline configurations. Shift is accomplished via wire/cable or mechanical means. The space-saving air shift cover maximizes clearance under the chassis. A genuine Chelsea part, sold by Pro Gear and Transmission.
