The Chelsea 221 Series Power Take-Off, part number 221ZEAHX-W4XK or 221ZEAHXW4XK, is a 6-bolt mounted PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. Shift is accomplished via wire/cable mechanical actuation. The 1-1/4" round output shaft with keyway is driven through a cast iron housing fitted with tapered cone output bearings for strong load-bearing capability. Output power ranges from 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Intermittent torque is rated up to 250 lb-ft (339 Nm); verify actual ratings on the Chelsea application pages for your specific transmission. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino. Greaseable pump shafts help reduce spline fretting and corrosion over time. Call us to confirm proper fit for your application.
