The Chelsea 221 Series Power Take-Off, part number 221ZLAHX-W3XQ or 221ZLAHXW3XQ, is a 6-bolt mounted PTO built for low-speed, heavy-duty vocational work. It uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque (339 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key suits a wide range of pump and driveline connections. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing is available in standard or low-profile configurations, and greaseable pump shafts help prevent spline fretting over time.
