The Chelsea 221 Series Power Take-Off Assembly, part number 221XLDAX-A3XD or 221XLDAXA3XD, is a 6-bolt mounted PTO built for low-speed, heavy-duty service on Allison, Eaton/Fuller, Volvo/Mack, Hino, and other transmission platforms. Shift actuation is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers 46-55 HP output power, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque is rated up to 250 lb-ft (339 Nm) -- verify against the application pages for your specific installation. The cast iron housing is available in standard or low-profile configurations, and greaseable pump shafts help combat spline fretting and corrosion over the long haul.
