The Chelsea 221 Series Power Take-Off, part number 221XEAJP-A5RA or 221XEAJPA5RA, is a 6-bolt mounted PTO designed for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. Shift type is wire/cable mechanical. The 1-1/4" round output shaft accepts a keyway and is supported by tapered cone bearings for higher load capacity than needle-bearing designs. Output power spans 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Greaseable pump shafts help reduce spline fretting and corrosion. The cast iron housing is available in a standard or special low-profile configuration. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others.
