The Chelsea 221 Series Power Take-Off, part number 221XEAKP-M6XK or 221XEAKPM6XK, is a 6-bolt, wire/cable mechanical-shift PTO built for low-speed, heavy-duty work. Output is delivered through a 1-1/4" round shaft with key, rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an intermittent torque rating up to 250 lb-ft (339 Nm) -- verify actual torque against the application pages for your specific installation. The cast iron housing seats tapered cone output bearings for stronger load capacity than needle-bearing designs. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. Greaseable pump shafts help fight spline fretting and corrosion over time.
