The Chelsea 447 Series Power Take-Off, part number 447XSESX-X3XK or 447XSESXX3XK, is a 6-bolt PTO engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference inside the transmission PTO aperture, which is the problem the 447 Series was built to solve. Shift options include wire/cable and mechanical. The output shaft is a 1-1/4" round with keyway. Intermittent torque ratings fall in the 201-300 lb-ft range; check the Chelsea application pages for the torque rating specific to your configuration. Output power is rated at 36-45 HP, with shaft power of 21 HP at 500 RPM and 43 HP at 1,000 RPM. 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 full range of shift and output options found in the popular 442 Series, and adds special options for Eaton FS series transmissions. The 447 uses tapered bearings instead of needle bearings for greater load-bearing capability. Twenty-six output options are available across the series, including Chelsea's 360-degree rotatable flange, 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.Parts Manual: Chelsea 447 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
