The Chelsea 221 Series Power Take-Off, part number 221XEAJP-A4XK or 221XEAJPA4XK, is a 6-bolt, mechanically shifted PTO designed for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It mounts to Allison, Eaton/Fuller, Volvo/Mack, Hino, and other compatible transmissions. The output shaft is a 1-1/4" round with keyway. Shift is wire/cable mechanical. Output power ranges from 46 to 55 HP (31 to 40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing uses tapered cone output bearings for load capacity, and greaseable pump shafts help reduce spline fretting and corrosion. A low-profile housing option is available for tight clearance installations. Call us to confirm proper fit for your transmission and application.
