The Chelsea 221 Series Power Take-Off Assembly, part number 221RCAJP-W5RA or 221RCAJPW5RA, is a 6-bolt mounted PTO designed for low-speed, heavy-duty vocational applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and accepts a 1-1/4" round output shaft with keyway. Intermittent torque rating for the 221 Series reaches 250 lb-ft (339 Nm); verify actual rating for your specific application on the Chelsea application pages. Shaft power output reaches 48 HP at 1,000 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, and Hino. The cast iron housing with tapered cone output bearings provides load-bearing strength beyond what needle bearings offer. A greaseable pump shaft reduces spline fretting and corrosion. Standard and low-profile housing options are available. Call us to confirm proper fit for your transmission and application.
