The Chelsea 541-NAUAXK or 541NAUAXK is a rear-mount power take-off assembly designed for Eaton/Fuller transmissions, including the Advantage and UltraShift series. It uses Chelsea's Thrushaft® mounting system, which requires only three fasteners and eliminates backlash adjustment at installation. The output shaft is a 1-1/2"-10T spline with a 1410 series companion flange. Shift type is lever/mechanical. Intermittent torque capacity is up to 400 lb-ft (542 Nm); verify actual ratings on the Chelsea application pages for your specific transmission. Output power reaches 56+ HP and 76 HP at 1,000 RPM. The rear-mount configuration keeps the undercarriage clear for pump or driveline installations. Call us to confirm proper fit for your application.
