The Chelsea 871XGFJP-D3AB is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous duty use. Its compact housing is engineered to reduce clearance conflicts during installation, and multiple assembly arrangements expand mounting options. The bearing cap is ductile iron, 117% stronger than the gray iron used in earlier designs, and an o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. The 871 Series supports nine speed ratios and thirteen output configurations, making it a fit for fire and rescue, refuse, truck crane, and pumper-cleaner applications.
