The Chelsea 660GRAHX-V3XD or 660GRAHXV3XD is a 660 Series Power Take-Off designed to fit most popular 6-bolt manual transmissions, including Eaton/Fuller, Volvo/Mack, and other compatible units. The 660 Series carries an intermittent torque rating up to 375 lb-ft, making it a step up from the 442 Series for demanding medium-to-heavy duty work. A cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft deliver load-bearing capability beyond needle-bearing designs. Shift options include wire/cable and mechanical. Output configurations in the 660 Series span SAE A, SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs.
