The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D5RY or 871XAFJPD5RY, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) and is rated for continuous-duty operation without derating. Nine speed ratios and thirteen output options give this unit broad application coverage across fire and rescue, refuse, truck crane, and pumper-cleaner 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, SmartStart, and Quiet Gear options are all available on this series. Call us to confirm the proper configuration for your application.
