The Chelsea 871 Series Power Take-Off Assembly, part number 871XAFJW-B3RS or 871XAFJWB3RS, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series delivers continuous torque 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 a wide range of mounting and drive options. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration-related wear. Available options include Wet Spline pump flange, Quiet Gear input, SmartStart for reduced shock load at start-up, and Electronic Overspeed Control (EOC). The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm proper fit for your application.
