The Chelsea 221ZEAKP-M6XE or 221ZEAKPM6XE is a 6-bolt power take-off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other compatible units. The shift mechanism is wire/cable mechanical, and the output shaft is a 1-1/4" round shaft with key. Intermittent torque is rated at 250 lb-ft (339 Nm) -- verify actual ratings on Chelsea application pages for your specific setup. Output power reaches 48 HP (36 kW) at 1,000 RPM. The cast iron housing supports tapered cone output bearings for strong load capacity, and greaseable pump shafts help reduce spline fretting and corrosion.
