Chelsea part 871XCFJP-G5RS or 871XCFJPG5RS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. The compact housing reduces clearance issues during installation, and multiple assembly arrangements expand mounting possibilities. Continuous torque capacity for the 871 Series reaches up to 670 lb-ft (908 N-m), with nine speed ratios and thirteen output options to match a wide range of driven equipment. 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. Optional features include Quiet Gear input, SmartStart shock-load reduction, Wet Spline pump flange for extended PTO and pump shaft life, and Electronic Overspeed Control (EOC). The 871 Series replaces the Chelsea 870 Series PTO. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
