Description
The Chelsea 447 Series Power Take-Off Assembly, part number 447XSESX-A5XD or 447XSESXA5XD, is a 6-bolt mount PTO designed to eliminate internal interference within the transmission PTO aperture. It uses a one-piece input gear with a space between the two sets of gear teeth, which prevents contact with adjacent gears found on certain Eaton/Fuller, ZF, and other transmission housings. Shift is wire/cable mechanical. The output shaft is a 1-1/4″ round shaft with keyway. Intermittent torque capacity for this series ranges from 201 to 300 lb-ft; check application pages for the actual torque rating specific to this configuration. Shaft power output is rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 447 Series shares the broad option range of the popular 442 Series and adds special configurations for Eaton FS series and Nissan/UD MLS series transmissions, where an adapter or installation kit may be required. Strong tapered bearings replace needle bearings for greater load-bearing capability under demanding vocational duty cycles. 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 truck and trailer, snow and ice removal equipment, and fire and rescue vehicles.
