The Chelsea 447 Series Power Take-Off Assembly, part number 447KWESX-W3RA or 447KWESXW3RA, is a 6-bolt mounted PTO designed to eliminate internal gear interference problems within the transmission PTO aperture. A one-piece input gear with a space between its two sets of gear teeth prevents adjacency conflicts that cause fitment headaches on many transmission housings. This unit shifts via wire/cable mechanical actuation and accepts a 1-1/4" round output shaft with keyway. Series output ratings reach 21 HP at 500 RPM and 43 HP at 1,000 RPM, with intermittent torque up to 225 lb-ft (check application pages for actual torque ratings). Compatible transmissions include Eaton/Fuller, ZF, and other manufacturers. Call us to confirm proper fit for your specific transmission.
