The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D3XV or 871XAFJPD3XV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 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 give technicians broad flexibility across fire and rescue, refuse, pumper/cleaner, and crane truck installations. The ductile iron bearing cap is 117% stronger than the gray iron cap it replaced, and an O-ring seal between the housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your specific transmission and application.
