The Chelsea 871 Series Power Take-Off, part number 871XBFJP-D3AC or 871XBFJPD3AC, is a 10-bolt hydraulic PowerShift PTO engineered for Allison transmissions. The 871 Series carries continuous torque ratings up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output configurations give this unit a broad fit across fire and rescue, truck crane, pumper cleaner, and refuse applications. A ductile iron bearing cap - 117% stronger than gray iron - and an O-ring sealing configuration between the housing and bearing cap reduce vibrational effects and improve clamp load. Optional Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) expand the application envelope. Call us to confirm the correct configuration for your specific installation.
