The Chelsea 871 Series Power Take-Off, part number 871XBFJP-H5AC or 871XBFJPH5AC, 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 use. Nine speed ratios and thirteen output options give it wide application coverage across fire and rescue, truck crane, pumper cleaner, and refuse equipment. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. The optional Wet Spline pump flange extends both PTO and pump shaft service life. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your application.
