The Chelsea 221 Series Power Take-Off Assembly, part number 221XEAJP-W3XD or 221XEAJPW3XD, is a 2-gear, 6-bolt PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and mounts to Allison, Eaton/Fuller, Volvo/Mack, Hino, and other compatible transmissions. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque (verify against application pages for your specific installation). Shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing is available in standard or low-profile configurations, and greaseable pump shafts help reduce spline fretting and corrosion. Call us to confirm proper fit for your transmission and application.
