The Chelsea 447KUESX-P5RK is a 447 Series Power Take-Off unit built on a 6-bolt mounting pattern. The 447 Series uses a one-piece input gear with a space between its two sets of gear teeth, designed to eliminate interference problems inside the transmission PTO aperture, including on Eaton FS series and Nissan/UD MLS series transmissions. Shift options include wire/cable and mechanical. Output is through a round shaft with a 1-inch, 1/4-inch key. The series delivers shaft power of 21 HP at 500 RPM and 43 HP at 1,000 RPM, with intermittent torque ratings from 201 to 300 lb-ft. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
