The Chelsea 877 Series Power Take-Off, part number 877XKFJP-M5XV or 877XKFJPM5XV, is a 10-bolt, constant-mesh PTO designed for Allison transmissions and high-torque, continuous-duty applications. The output shaft is a 1-1/2" 10-spline configuration with a 1410 companion flange. Continuous torque capacity reaches 670 lb-ft (908 Nm); intermittent torque is rated at 501+ lb-ft. Shaft power output is 64 HP at 500 RPM and 128 HP at 1000 RPM. The compact housing lowers overall height to reduce clearance conflicts, and the output flange rotates to maximize installation flexibility. Wet Spline Technology helps extend service life for both the PTO and connected pump shaft. This unit fits snow and ice, refuse, aerial, and defense truck applications. Call us to confirm proper fit for your specific transmission and chassis.
