The Chelsea 871 Series Power Take-Off 871XCFJP-D5XV or 871XCFJPD5XV is a 10-bolt, hydraulic PowerShift PTO designed for Allison transmissions. This series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options cover a wide range of installation requirements, from fire and rescue to refuse and truck crane applications. 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 the vibrational stresses common in modern engine designs. Optional Wet Spline pump flange, Quiet Gear input, SmartStart, and Electronic Overspeed Control (EOC) round out the feature set. Call us to confirm proper fit for your application.
The 871 Series replaces the Chelsea 870 Series PTO. It is the only Chelsea PTO to offer all three of Chelsea's high-demand options together: Wet Spline, SmartStart, and Quiet Gear. Markets served include fire and rescue, truck cranes, pumper cleaner, and refuse.
