The Chelsea 871 Series Power Take-Off, part number 871XDFJP-G3SV or 871XDFJPG3SV, is a 10-bolt hydraulic PowerShift PTO engineered 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 use. Nine speed ratios and thirteen output options cover a wide range of installation requirements, and the compact housing keeps clearance conflicts to a minimum. 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 while improving clamp load. Wet Spline, SmartStart, and Quiet Gear options are all available on this series. Common markets include fire and rescue, truck cranes, refuse, and pumper-cleaner equipment. Call us to confirm the right configuration for your application.
