The Chelsea 680ZSDAX-P5RY or 680ZSDAXP5RY 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 features a cast iron housing with tapered cone bearings on the output shaft and on the input shaft, delivering higher load-bearing capability than needle-bearing designs. The series covers Eaton Fuller, Mack, and Daimler/Detroit manual transmission applications, with a deep-mount housing option available for Mack. It is built for higher-torque demands such as pneumatic blowers, aerial equipment, dump truck hydraulics, fire and rescue, refuse, and snow removal service. Call us to confirm proper fit for your specific transmission and application.
