The Chelsea 447XQETX-H3XK is a 447 Series Power Take-Off built with a one-piece input gear that spaces its two sets of gear teeth to eliminate interference problems inside the transmission PTO aperture. The 447 Series mounts with a 6-bolt pattern and requires no adapter plate on most applications. Output is through a round shaft with a 1-inch, 1/4-inch key. Shift options include wire/cable and mechanical. The series carries an intermittent torque range of 201-300 lb-ft and delivers up to 43 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load capacity. Available with special installation kits for Eaton FS series and Nissan/UD MLS series transmissions.
