The Chelsea 871XAFJP-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 up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output configurations give installers a wide range of application flexibility. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, addresses the vibrational demands of modern engine designs. The compact housing profile reduces clearance conflicts during installation. Optional features include Wet Spline pump flange, SmartStart for reduced start-up shock load, Quiet Gear input, and Electronic Overspeed Control (EOC). The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm proper fit for your specific transmission and application.
