The Chelsea 221XEAKP-M4XK or 221XEAKPM4XK is a 6-bolt power take-off assembly from the Chelsea 221 Series, suited for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and mounts to Allison, Eaton/Fuller, Volvo/Mack, Hino, and other transmission housings. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque (check application pages for your specific rating). Shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing is available in standard or low-profile configuration. Greaseable pump shafts reduce spline fretting and corrosion. Call us to confirm proper fit for your application.
