The Chelsea 871 Series Power Take-Off, part number 871LCFJW-B3TY or 871LCFJWB3TY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The compact housing is engineered to reduce clearance issues during installation, and multiple assembly arrangements expand mounting possibilities. Continuous torque capacity for the 871 Series reaches up to 670 lb-ft (908 N-m), with no derating required for continuous-duty use. Nine speed ratios and thirteen output configurations give this unit broad application flexibility across fire and rescue, refuse, truck cranes, and pumper-cleaner work. The ductile iron bearing cap is 117% stronger than gray iron, and the o-ring sealing configuration between the housing and cap improves clamp load while reducing vibration-related wear. The Wet Spline pump flange extends service life for both the PTO and the driven pump shaft. Optional SmartStart reduces shock load at start-up, and Electronic Overspeed Control (EOC) protects downstream equipment. Call us to confirm proper fit for your application.
