The Chelsea 680XFAHX-A5RB is an 8-bolt mount Power Take-Off from the 680 Series, designed for medium to heavy-duty manual transmission applications including Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other transmission makes. The 680 Series features a cast iron housing with tapered cone bearings on the output shaft, and the input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. The series is rated for intermittent torque in the 301-400 lb-ft range and supports continuous operation with a 30 percent de-rating. Shift is via wire/cable or mechanical. Common applications include aerial, dump truck, refuse, blower and product pump, snow and ice removal, and fire and rescue equipment. Call us to confirm proper fit for your application.
