The Chelsea 871LCFJW-D5TF or 871LCFJWD5TF is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous-duty torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous operation. Nine speed ratios and thirteen output configurations give this unit broad installation flexibility, while the compact housing keeps clearance issues in check. 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 loads common with modern engine designs. Optional Wet Spline pump flange, SmartStart, Quiet Gear input, and Electronic Overspeed Control (EOC) extend equipment protection across demanding vocational cycles including fire and rescue, refuse, truck cranes, and pumper-cleaner applications. Call us to confirm proper fit for your specific Allison transmission and application.
