The Chelsea 447XSETX-H3XY 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, a design that eliminates interference problems inside the transmission PTO aperture. Tapered bearings replace the needle bearings used in comparable units, providing greater load-bearing capability. Shift options for this series include wire/cable and mechanical. Output is delivered through a round shaft with a 1-1/4" key. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft; continuous torque ratings are de-rated 30% from intermittent values. Check application pages for actual torque ratings specific to your installation. Sold by Pro Gear and Transmission.
