The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D5SV or 871XAFJPD5SV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. Continuous torque capacity reaches 670 lb-ft (908 N-m), and the unit is rated for continuous-duty operation without derating. Nine speed ratios and thirteen output options give this PTO broad application coverage across fire and rescue, refuse, truck crane, and pumper cleaner equipment. The ductile iron bearing cap is 117% stronger than gray iron, while an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series is the only Chelsea PTO to offer all three premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
