The Chelsea 871 Series Power Take-Off, part number 871XEFJP-D5AC or 871XEFJPD5AC, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The compact housing reduces clearance issues and supports continuous-duty operation with torque capacity up to 670 lb-ft (908 N-m). Nine available speed ratios and thirteen output options cover a wide range of hydraulic applications including fire and rescue, refuse, truck cranes, and pumper-cleaner units. 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 demands of modern engine designs. Optional Wet Spline pump flange, SmartStart, Quiet Gear input, and Electronic Overspeed Control (EOC) make this one of Chelsea's most versatile PTO platforms. Call us to confirm proper fit for your specific transmission and application.
