The Chelsea 541-NBJPXK or 541NBJPXK is a rear-mount power take-off assembly designed for Eaton Fuller transmissions, including the Advantage and UltraShift Series. It uses Chelsea's Thrushaft® installation method, which requires only three fasteners and eliminates backlash adjustment, reducing installation time compared to conventional PTO mounting. The output shaft is a 1-1/2"-10T spline with a 1410 Series companion flange, suited for driveline-connected applications. Shift type is lever/mechanical. Intermittent torque capacity runs up to 400 lb-ft (check application pages for actual torque ratings). Shaft power output is 38 HP at 500 RPM and 76 HP at 1000 RPM. The rear-mount design opens up space under the vehicle for pump or accessory mounting. Call us to confirm proper fit for your specific transmission configuration.
