871XEFJP-N5XV Chelsea PTO Assembly

The Chelsea 871XEFJP-N5XV or 871XEFJPN5XV is a 10-bolt, hydraulic PowerShift Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give this PTO broad application flexibility across fire and rescue, refuse, pumper cleaner, and truck crane equipment. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. The Wet Spline pump flange protects both the PTO and pump shaft. SmartStart and Quiet Gear options are also available for this series. Call us to confirm proper fit for your application.
