The Chelsea 871 Series Power Take-Off, part number 871XBFJP-D3XV or 871XBFJPD3XV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The compact housing reduces clearance issues common in tight installations, and the series supports continuous-duty operation without derating. Torque capacity reaches up to 670 lb-ft (908 N-m), with nine available speed ratios and thirteen output options covering a broad range of hydraulic pump configurations. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap address the vibrational stresses of modern engine designs. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your application.
