The Chelsea 680ZSDAX-P5XD or 680ZSDAXP5XD is an 8-bolt Power Take-Off from the Chelsea 680 Series, designed for medium to heavy duty manual transmission applications. The 680 Series fits Eaton/Fuller, Mack, Volvo/Mack, and Daimler/Detroit transmissions with an 8-bolt PTO aperture, including a deep mount housing option for Mack applications. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 680 Series, which targets higher-torque jobs such as pneumatic blowers. The series supports wire/cable or mechanical shift types, and output options include SAE A, SAE B, and SAE C pump flanges as well as driveline configurations. Continuous operation is supported with a 30% de-rating. Call us to confirm proper fit for your specific transmission and application.

Additional Information
The Chelsea 680 Series PTO is commonly used in aerial, fire and rescue, dump truck, refuse, snow and ice removal, service truck, and blower/product pump applications. The space-saving shift cover design allows maximum clearance under the truck. The input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. The 680 Series offers 32 output configurations and four internal speed ratios, making it adaptable across a wide range of vocational installations.
