The Chelsea 680GSAHX-P5XY is a medium-to-heavy duty Power Take-Off from the Chelsea 680 Series, built for transmissions with an 8-bolt PTO aperture. The 680 Series is a proven platform for higher-torque demands such as pneumatic blowers, dump trucks, and aerial applications. Its cast iron housing and tapered cone bearings on the output shaft provide durability under sustained load, and the air shift cover is designed to maximize clearance under the truck. The series covers Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other transmission families, and includes a deep mount housing option specifically for Mack applications.
