The Chelsea 447 Series Power Take-Off, part number 447XSETX-P5XK or 447XSETXP5XK, is a 6-bolt mounted PTO engineered specifically to eliminate internal interference problems within the transmission PTO aperture. It uses a one-piece input gear with a gap between its two sets of gear teeth, solving adjacent-gear interference issues that can arise with certain transmissions. Shift type is 12V electric/air shift. The 447 Series delivers up to 43 HP at 1,000 RPM, with intermittent torque ratings in the 201-300 lb-ft range (verify actual torque via the Chelsea application pages for this configuration). 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 wide shift and output flexibility of the popular 442 Series, and adds special options to simplify installation on Eaton FS series transmissions. The series features tapered bearings rather than needle bearings for greater load-bearing capability. Twenty-six output options, four internal speed ratios, and eleven shift options are available across the 447 Series. Typical vocational applications include utility trucks, dump trucks, snow and ice removal equipment, aerial equipment, and fire and rescue vehicles.
