The Chelsea 871 Series Power Take-Off, part number 871XHFJP-N5XV or 871XHFJPN5XV, is a 10-bolt PowerShift (hydraulic) PTO engineered for Allison transmission applications. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options give you broad flexibility across fire and rescue, refuse, pumper-cleaner, and truck crane installations. The compact housing keeps clearance concerns in check, and the ductile iron bearing cap is 117% stronger than gray iron. An O-ring sealing configuration between the housing and bearing cap resists vibrational stress from modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are all available on this series. Call us to confirm proper fit for your application.
