The Chelsea 871 Series Power Take-Off Assembly, part number 871XCFJP-B5RZ or 871XCFJPB5RZ, 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 operation. Nine speed ratios and thirteen output options give this unit a wide range of installation flexibility, while the compact housing design reduces clearance concerns during installation. A ductile iron bearing cap provides significantly greater strength than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-related wear and improves clamp load. The optional Wet Spline pump flange, SmartStart, and Quiet Gear input are all available within this series. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
