The Chelsea 877XKFJP-M3XV is a constant-mesh power take-off from the 877 Series, designed for 10-bolt Allison transmission applications with high torque demand and continuous-duty operation. The output shaft is a 1-1/2" 10-tooth spline with a 1410 companion flange. Continuous torque rating reaches 670 lb-ft (908 Nm); intermittent torque is rated at 501+ lb-ft. Shaft power runs 64 HP at 500 RPM and 128 HP at 1000 RPM. The compact housing lowers overall height to reduce clearance conflicts, and the rotatable output flange gives installers flexibility to avoid interference. Wet Spline Technology is incorporated to extend service life for both the PTO and the pump shaft. Call us to confirm proper fit for your specific application.
