The Chelsea 447 Series Power Take-Off, part number 447KSESX-A3RA or 447KSESXA3RA, is a 6-bolt mounted PTO designed around a one-piece input gear with a gap between its two sets of gear teeth. That design eliminates internal interference problems at the transmission PTO aperture, making it a practical choice for transmissions where adjacent gear clearance is tight. Compatible with Eaton/Fuller, ZF, and other transmission manufacturers. Shift is via wire/cable or mechanical actuation. The output shaft is a 1-1/4" round, also available with a keyway. Intermittent torque rating ranges from 201 to 300 lb-ft (301 to 400 Nm); check application pages for the actual rating for your configuration. Shaft power runs 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 shift and output flexibility of the popular 442 Series while adding special options for Eaton FS series transmissions. The series features tapered bearings rather than needle bearings for increased load-bearing capability. Twenty-six output options are available across the series, including Chelsea's 360-degree rotatable flange, along with four internal speed ratios and eleven shift options. Typical applications include utility trucks, dump trucks and trailers, snow and ice removal equipment, aerial equipment, and fire and rescue vehicles.Series reference documents: 447 Series Parts List (HY25-2442-M1_US); 340/348/442/447/489/660/680/823/863/880 Series Owner's Manual; Chelsea PTO General Information Catalog.
