The Chelsea 447 Series Power Take-Off Assembly, part number 447KUESX-A3RA or 447KUESXA3RA, is a 6-bolt mounted PTO built around a one-piece input gear with a space between two sets of gear teeth. That design specifically eliminates gear interference inside the transmission PTO aperture, a common fitment problem on a wide range of transmissions including Eaton/Fuller, ZF, and other manufacturers. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Output power ranges from 36 to 45 HP (31-40 kW), with shaft power rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Intermittent torque is rated up to 225 lb-ft (305 Nm); check the Chelsea application pages for your specific torque rating. Tapered bearings replace needle bearings for greater load-bearing capability. No adapter plate is required for installation. Call us to confirm proper fit for your application.
