The Chelsea 221 Series Power Take-Off Assembly, part number 221ZEAKP-M6AF or 221ZEAKPM6AF, is a 6-bolt, wire/cable mechanical-shift PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. The 1-1/4" round output shaft with key delivers up to 250 lb-ft (339 Nm) intermittent torque. Shaft power output runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing uses tapered cone output bearings for strong load-bearing capability, and greaseable pump shafts reduce spline fretting and corrosion. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. Available in standard or low-profile housing configurations.
