The Chelsea 871 Series Power Take-Off Assembly, part number 871XJFJP-B3RS or 871XJFJPB3RS, 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 installers flexibility across a wide range of vocational applications including fire and rescue, refuse, truck cranes, and pumper-cleaner trucks. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Wet Spline lubrication, SmartStart, and Quiet Gear are all available on this series. The compact housing minimizes clearance concerns during installation. Call us to confirm proper fit for your specific transmission and application.
