The Chelsea 871 Series Power Take-Off, part number 871XDFJP-G3RS or 871XDFJPG3RS, is a compact 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous duty, making it a practical fit for fire and rescue apparatus, truck cranes, pumper cleaners, and refuse equipment. Nine speed ratios and thirteen output options give installers significant flexibility. 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 vibrational stress. Optional Wet Spline, SmartStart, and Quiet Gear configurations are all available within this series. Call us to confirm the correct configuration for your application.
