Shift is wire/cable or mechanical. The output shaft is a 1-1/4" round shaft with keyway. Intermittent torque rating for the 447 Series runs 201-300 lb-ft; check the Chelsea application pages for the torque rating specific to this configuration. Output power reaches 43 HP at 1,000 RPM.

Additional Information

The Chelsea 447 Series shares the broad option set of the popular 442 Series and adds special configurations for Eaton FS series and Nissan/UD MLS series transmissions, where an adapter or installation kit may be required. Strong tapered bearings replace needle bearings used in some comparable units, providing greater load-bearing capability. The series offers 26 output options including Chelsea's 360-degree rotatable flange, four internal speed ratios, and eleven shift options. Typical vocational applications include utility trucks, dump trucks and trailers, snow and ice removal equipment, fire and rescue vehicles, and service trucks.
