The Chelsea 871 Series Power Take-Off, part number 871XHFJP-D5RY or 871XHFJPD5RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The series carries a continuous torque rating up to 670 lb-ft (908 N-m), with no derating required for continuous duty operation. Nine speed ratios and thirteen output options give installation engineers wide flexibility across fire and rescue, truck crane, pumper cleaner, and refuse equipment. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Wet Spline, SmartStart, and Quiet Gear options are all available within this series. Call us to confirm proper fit and option configuration for your application.
