The Chelsea 541 Series Power Take-Off Assembly, part number 541-NATAXK or 541NATAXK, mounts on the rear countershaft of Eaton Fuller transmissions, including the Advantage and UltraShift Series. This unit uses Chelsea's Thrushaft® installation design, which requires only three fasteners and eliminates backlash adjustment, making installation faster than conventional rear-mount PTOs. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, suited for driveline-to-pump applications. Shift type is lever/mechanical. Intermittent torque capacity reaches up to 400 lb-ft (check application pages for actual torque ratings). Output power is 56+ HP, with shaft power rated at 38 HP at 500 RPM and 76 HP at 1,000 RPM. The rear-mount design provides additional product space beneath the vehicle. Call us to confirm proper fit for your specific Eaton Fuller transmission.
