The Chelsea 447XUESX-A3XJ is a 447 Series Power Take-Off built on Chelsea's problem-solving 447 platform. The 447 Series uses a one-piece input gear with a gap between its two sets of gear teeth, which eliminates interference problems inside the PTO aperture on transmissions that have adjacent gear interference. Mounting is a standard 6-bolt pattern with no adapter plate required. Output is via a round shaft with a 1-inch, 1/4-inch key. The 447 Series covers intermittent torque in the 201-300 lb-ft range and delivers up to 43 HP at 1,000 RPM. Shift options include wire/cable and mechanical. Sold by Pro Gear and Transmission.

Additional Information
The Chelsea 447 Series shares its option set with the popular 442 Series and adds special provisions for Eaton FS series and Nissan/UD MLS series transmissions, where an adapter or unique installation kit may be required. The 447 uses 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 series. Typical applications include utility trucks, dump truck and trailer, snow and ice removal, fire and rescue, and service trucks.Parts Manual: Chelsea 447 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
