The Chelsea 541-NBJ-Y-XV or 541NBJYXV is a rear-mount Power Take-Off assembly from the Chelsea 541 Series, designed for Eaton Fuller transmissions including the Advantage and UltraShift Series that feature a Thrushaft opening. This unit uses a lever, mechanical shift and delivers intermittent torque up to 400 lb-ft (542 Nm - check application pages for actual ratings). Output is via a 1-1/2"-10T spline with a 1410 companion flange, suited for direct driveline connections. Shaft power is rated at 38 HP at 500 RPM and 76 HP at 1000 RPM. The rear-mount design provides additional clearance and space under the vehicle for auxiliary equipment. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 541 Series mounts on the rear countershaft of Eaton Fuller transmissions and requires only three fasteners for installation with no backlash adjustment needed. Cast iron housing and heavy-duty bearings support torque capacity up to 400 lb-ft. Typical applications include tow and recovery trucks, aerial devices, service trucks, dump trucks, and agricultural feeders and spreaders. Note: Parker Chelsea lists the 541 Series as no longer in current production. Call Pro Gear and Transmission to confirm availability and fitment for your specific transmission configuration.
