The Chelsea 680XSDAX-A3XY is a 680 Series Power Take-Off built for medium- to heavy-duty manual transmission applications with an 8-bolt PTO aperture. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft, giving it a higher torque rating than needle-bearing designs. The series is rated for intermittent torque from 301 to 400 lb-ft (501+ Nm), with continuous operation supported at a 30% de-rating. Shift types across the 680 Series include wire/cable and mechanical. Compatible transmission manufacturers include Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and others. The 680 Series also offers a deep-mount housing option suited to Mack transmission applications. Common working environments include dump trucks, refuse vehicles, aerial equipment, blower and product pump systems, and fire and rescue apparatus. Call us to confirm proper fit for your specific transmission and application.
