The Chelsea 447 Series Power Take-Off Assembly, part number 447XSESX-W3XK or 447XSESXW3XK, is a 6-bolt mounted PTO engineered to eliminate internal gear interference problems that occur on a wide variety of transmissions. It uses a one-piece input gear with a space between its two sets of gear teeth, which clears the PTO aperture on transmissions where adjacent gear interference would otherwise be an issue. Shift is accomplished via wire/cable or mechanical actuation. The output shaft is a 1-1/4" round configuration, with or without a keyway. This unit is compatible with Eaton/Fuller, ZF, and other transmission manufacturers. Output power for the 447 Series reaches 43 HP at 1,000 RPM, with intermittent torque ratings in the 201-300 lb-ft range (check application pages for your specific torque rating). For continuous-duty use, de-rate the intermittent torque rating by 30%. Call us to confirm proper fit for your truck and transmission.
