The Chelsea 221 Series Power Take-Off Assembly, part number 221XEAHX-A5XD or 221XEAHXA5XD, is a 6-bolt, wire/cable mechanical-shift PTO built for low-speed, heavy-duty service. Output is rated at 46-55 HP (31-40 kW), with intermittent torque up to 250 lb-ft (339 Nm) - verify actual ratings on the Chelsea application pages for your specific setup. The 1-1/4" round output shaft is available with a keyway. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, and Hino. The cast iron housing uses tapered cone output bearings for greater load-bearing capability over needle bearing designs, and greaseable pump shafts help reduce spline fretting and corrosion. A low-profile housing option provides added clearance. Common applications include dump trucks, tow and recovery, and aerial equipment. Call us to confirm proper fit for your transmission and application.
