The Chelsea 680QHMEX-66RK is a 680 Series Power Take-Off built for 8-bolt manual transmission applications, including Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other compatible transmissions. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft for strong load-bearing capability. Output options include SAE A, SAE B, and ISO 7652 pump flanges as well as driveline configurations. Shift is via wire/cable or mechanical means. The series is rated for intermittent torque in the 301-400 lb-ft range and is designed for higher-torque vocational demands such as pneumatic blowers, aerial equipment, and dump applications.
