The Chelsea 447XSETX-W5RK is a 447 Series Power Take-Off built on a 6-bolt mounting pattern. The 447 Series uses a one-piece input gear with a space between its two gear-tooth sets, which eliminates interference problems inside the transmission PTO aperture - a common issue on installations where adjacent gears conflict. Tapered bearings replace the needle bearings found in earlier designs, providing greater load-bearing capability. Shift options include wire/cable and mechanical. The output shaft is a round shaft with a 1-1/4-inch key. Intermittent torque for the series ranges from 201 to 300 lb-ft (305 Nm), with shaft power rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Pro Gear and Transmission carries this genuine Chelsea unit for utility truck, dump truck, snow and ice removal, and vocational equipment applications.
