The Chelsea 660 Series Power Take-Off Assembly, part number 660XSJAX-A4XV or 660XSJAXA4XV, is a 6-bolt PTO built for medium- to heavy-duty vocational applications including dump trucks, aerial devices, service trucks, and snow removal equipment. It uses a wire/cable mechanical shift and delivers an intermittent torque capacity up to 375 lb-ft (508 Nm). The 1-1/4" round output shaft with key fits transmissions from Eaton/Fuller, Volvo/Mack, Hino, and other compatible manufacturers. Shaft power output reaches 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. The cast iron housing and tapered cone bearings on the output shaft contribute to long service life, while tapered bearings on the input shaft provide greater load-bearing capability than needle-bearing designs. Call us to confirm proper fit for your application.
