The 1-1/4" round output shaft uses a 5/16" key and supports intermittent torque in the 201-300 lb-ft range, with continuous torque rated up to 300 lb-ft (consult the Chelsea application pages for torque ratings specific to your transmission). Shaft power output reaches 57 HP at 1,000 RPM. Compatible transmissions span Allison, Eaton/Fuller, Ford, Aisin, Volvo/Mack, and RAM applications.
