The Chelsea 680 Series Power Take-Off, part number 680XSAHX-A3AZ or 680XSAHXA3AZ, is an 8-bolt mount PTO assembly with wire/cable mechanical shift and a 1-1/4" round output shaft with keyway. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft, giving it a high intermittent torque rating in the 301-400 lb-ft range (check application pages for actual torque ratings). Shaft power output runs from 36 HP at 500 RPM to 107 HP at 1,500 RPM. The deep mount housing option makes this a strong fit for Mack transmission applications, and the series is purpose-built for high-torque demands like pneumatic blowers. Covers most manual transmissions with 8-bolt PTO apertures, including Eaton/Fuller and Volvo/Mack. Call us to confirm proper fit for your application.
