Additional Information
The Chelsea 447 Series shares its shift and output option range with the popular 442 Series and adds further options to simplify installation on Eaton FS series and Nissan/UD MLS series transmissions, where an adapter or special installation kit may be required. The series uses tapered bearings rather than 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, aerial equipment, dump trucks, snow and ice removal units, and fire and rescue vehicles. Part number 447XQETX-A5XY is also referenced as SP447XQETX-A5XY in some catalog systems.Parts Manual: Chelsea 447 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
