The Chelsea 871XGFJP-B5AC or 871XGFJPB5AC is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 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 configurations give installers broad flexibility. A ductile iron bearing cap delivers 117% greater strength than gray iron, and the O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The compact housing height eases clearance concerns in tight installations. Optional Wet Spline, SmartStart, and Quiet Gear features are available within the 871 Series. The 871 Series replaces the Chelsea 870 Series. Call us to confirm proper fit for your application.
