Description
The Chelsea 871XAFJP-B3BV or 871XAFJPB3BV is a 10-bolt hydraulic PowerShift Power Take-Off from the 871 Series, designed for Allison transmission applications. This series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. A ductile iron bearing cap provides 117% greater strength over gray iron, while an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Nine speed ratios and thirteen output options cover a wide range of installation requirements. Optional Quiet Gear input, SmartStart shock-load reduction, and a Wet Spline pump flange for extended PTO and pump shaft life are available within this series. The compact housing profile helps eliminate clearance conflicts in tight installations. Call us to confirm proper fit for your application.
