The Chelsea 877XBKVW-M3RS or 877XBKVWM3RS is a 10-bolt, constant mesh power take-off engineered for Allison transmission applications with demanding, continuous-duty workloads. The output shaft is a 1-1/2" 10-spline configuration with a 1410 companion flange. Continuous torque is rated at 670 lb-ft (908 Nm), with intermittent torque capability starting at 501 lb-ft. Shaft power reaches 128 HP at 1,000 RPM. The compact housing is designed to reduce clearance issues, and the output flanges are rotatable to further maximize installation clearance. Wet Spline Technology is integrated to extend the service life of both the PTO and the pump shaft. Call us to confirm proper fit for your specific application.
