The Chelsea 871XDQTP-D5AC or 871XDQTPD5AC is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options cover a wide range of installation requirements, and the compact housing height reduces clearance concerns in tight installations. This unit carries a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap to reduce vibrational effects and improve clamp load, and a wet spline pump flange that extends PTO and pump shaft service life. SmartStart and Electronic Overspeed Control (EOC) options are available within the series. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
