Description
The Chelsea 447 Series Power Take-Off Assembly, part number 447KQESX-A3XK or 447KQESXA3XK, is a 6-bolt mount PTO engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference problems within the PTO aperture on transmissions that have adjacent gear interference, with no adapter plate required for most installations. Shift type is wire/cable mechanical. The output shaft is a 1-1/4″ round with keyway. Intermittent torque rating falls in the 201-300 lb-ft range; check application pages for the actual torque rating for your specific vehicle. Compatible with Eaton/Fuller, ZF, and other transmission manufacturers. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 447 Series shares the broad option set of the popular 442 Series and extends it with configurations that simplify installation on Eaton FS series transmissions. Where the 442 uses needle bearings, the 447 steps up to tapered bearings for greater load-bearing capability. The series offers 26 output options including Chelsea’s 360-degree rotatable flange, four internal speed ratios, and eleven shift options. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, aerial equipment, and fire and rescue vehicles. Parker Chelsea documents available for this series include the 447 Series Parts List (HY25-2442-M1_US), the 340/348/442/447/489/660/680/823/863/880 Series Owner’s Manual, and the Chelsea PTO General Information Catalog.
