The Chelsea 871XFFJP-K5XV is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options give this unit broad application coverage across fire and rescue, refuse, truck crane, and pumper cleaner equipment. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap address the vibrational stress of modern engine designs. Wet Spline lubrication on the pump flange reduces wear on both the PTO output and the pump shaft. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single compact housing. Call us to confirm proper fit for your transmission and application.
