The Chelsea 221ZEAKP-M5GE or 221ZEAKPM5GE is a 6-bolt Power Take-Off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty vocational applications including dump trucks, tow and recovery, and aerial equipment. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft (339 Nm) intermittent torque; check application pages for the torque rating specific to your configuration. Output power runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino. Call us to confirm proper fit for your application.
The Chelsea 221 Series uses a cast iron housing with tapered cone output shaft bearings for strong load-bearing capability across vocational duty cycles. The series supports twenty-six output options, three internal speed ratios, and eleven shift options. A low-profile housing variant is available where underhood clearance is limited. Greaseable pump shafts address spline fretting and corrosion in applications where consistent lubrication can be a challenge. Typical applications include dump trucks, tow and recovery rigs, and aerial equipment. Part number 221ZEAKP-M5GE is also referenced as SP221ZEAKP-M5GE.
