The Chelsea 871 Series Power Take-Off Assembly, part number 871XAFJP-B3XV or 871XAFJPB3XV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine speed ratios and thirteen output options cover a wide range of installation requirements. The compact housing keeps clearance issues to a minimum, and a ductile iron bearing cap rated 117% stronger than gray iron adds durability at the bearing interface. An O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibrational stress from modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are all available within the 871 Series. This unit also replaces the earlier Chelsea 870XAFJP-B3XV. Call us to confirm proper fit for your application.
