The Chelsea 871XDQTP-D3AC or 871XDQTPD3AC is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. It draws on the 871 Series' continuous-duty torque capacity of up to 670 lb-ft (908 N-m) with nine available speed ratios and thirteen output options. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration effects. Wet Spline lubrication on the pump flange protects both the PTO and pump shaft during operation. SmartStart reduces shock loads at start-up, and Electronic Overspeed Control (EOC) safeguards driven equipment. The compact housing keeps installation clearances manageable. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm proper fit for your application.
