The Chelsea 871 Series Power Take-Off, part number 871XDFJP-B5RK or 871XDFJPB5RK, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m), with shaft power rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM. Nine available speed ratios and thirteen output options give fleet and spec engineers broad flexibility across demanding applications including fire and rescue, refuse, truck cranes, and pumper-cleaner units. 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. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available. Call us to confirm proper fit and assembly arrangement for your application.
