The Chelsea 447KSESX-W3RA or 447KSESXW3RA is a 6-bolt power take-off from the Chelsea 447 Series, engineered with a one-piece input gear that spaces its two sets of gear teeth to prevent interference inside the transmission PTO opening. Shift is wire/cable or mechanical. The output is a rotatable SAE B 2-bolt flange with a 7/8" 13-tooth SAE B shaft, and shaft power runs 21 HP at 500 RPM and 43 HP at 1,000 RPM. Intermittent torque range for the 447 Series runs 201-300 lb-ft (301-400 Nm); check the Chelsea application pages for the actual rating for your specific configuration. Compatible transmissions include Eaton/Fuller, ZF, and other manufacturers. The 447 Series uses tapered bearings in place of needle bearings for improved load capacity. Call us to confirm proper fit for your application.
