The Chelsea 871XEFJP-B3AB is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. This series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give you broad installation flexibility, while the compact housing keeps clearance problems at bay. 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 and resists the vibrational stresses of modern engine designs. Wet Spline pump flange lubrication, the SmartStart shock-load reduction option, and Quiet Gear input option are all available within this series. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm proper fit for your application.
