The Chelsea 871 Series Power Take-Off (P/N 871XHFJP-B3SV or 871XHFJPB3SV) is a 10-bolt, hydraulic PowerShift PTO designed for Allison transmissions. The compact housing reduces clearance issues during installation, while nine available speed ratios and thirteen output options give the unit a broad range of application coverage. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, addresses vibrational stress from modern engine designs. Continuous torque capacity reaches 670 lb-ft (908 N-m). The 871 Series is the only Chelsea PTO to offer all three premium options - Wet Spline, SmartStart, and Quiet Gear - in a single platform. Call us to confirm proper fit for your specific installation.
