The Chelsea 447KUESX-A3RK 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 sets of gear teeth, eliminating interference problems inside the transmission PTO aperture, a practical advantage on Eaton FS series and Nissan/UD MLS series installations. Shift options for this series include wire/cable and mechanical configurations. Output is delivered through a rotatable SAE B 2 or 4-bolt flange with a 7/8-inch 13-tooth SAE B shaft. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft (301 to 400 Nm); check application pages for the actual torque rating for this configuration. A genuine Chelsea part, available from Pro Gear and Transmission.
