The Chelsea 447XQETX-V3XK is a 447 Series Power Take-Off built on a 6-bolt mounting pattern with a round shaft output (1-1/4" key). The 447 Series uses a one-piece input gear with a gap between its two gear-tooth sets, a design that eliminates interference inside the transmission PTO opening without requiring an adapter plate. Tapered bearings replace the needle bearings found in earlier designs, adding load-bearing capacity. Shift options include wire/cable and mechanical, and the series offers 26 output configurations. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft; shaft power is rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Pro Gear and Transmission sells this as a genuine Chelsea unit.

Additional Information
The Chelsea 447 Series is suited for aerial, vocational, and municipal equipment applications including utility trucks, dump trucks, snow and ice removal vehicles, and fire and rescue apparatus. The series is compatible with Eaton FS series and Nissan/UD MLS series transmissions and may require a specific adapter or installation kit for those vehicles. Four internal speed ratios and 26 output options, including Chelsea's 360-degree rotatable flange, are available across the 447 Series lineup. Continuous torque should be de-rated 30% from the intermittent rating; consult the application pages for the actual torque rating for your specific installation.Parts Manual: Chelsea 447 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
