The Chelsea 221XEAKP-M4XD or 221XEAKPM4XD is a 6-bolt mounted power take-off assembly from the Chelsea 221 Series, designed for low-speed, heavy-duty vocational work including dump trucks, tow and recovery, and aerial equipment. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque (339 Nm); verify your actual rating against Chelsea application pages. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. A cast iron housing with tapered cone output bearings gives this unit a load-bearing advantage over needle-bearing designs. Greaseable pump shafts help reduce spline fretting and corrosion. Available in standard or low-profile housing configurations. Call us to confirm proper fit for your transmission and application.
