The Chelsea 871XEFJP-D5RK is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series features a ductile iron bearing cap rated 117% stronger than gray iron predecessors, along with an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce vibrational effects from modern engine designs. The series carries a continuous torque rating up to 670 lb-ft (908 Nm) with no derating required for continuous duty use. Nine speed ratios and thirteen output options give this PTO broad application flexibility across fire and rescue, refuse, truck crane, and pumper cleaner equipment. The 871 Series replaces the earlier Chelsea 870 Series.
