The Chelsea 871 Series Power Take-Off, part number 871XFFJP-D3RY or 871XFFJPD3RY, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options give the installer wide flexibility for fire and rescue, truck crane, pumper cleaner, and refuse applications. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce the vibrational effects of modern engine designs. The compact housing height keeps clearance issues to a minimum. Wet Spline, SmartStart, and Quiet Gear options are available within the 871 Series. Call us to confirm the correct configuration for your installation.
