The Chelsea 871 Series Power Take-Off, part number 871XDFJP-K5XV or 871XDFJPK5XV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series succeeds the popular 870 Series, carrying forward the same mounting footprint while adding a ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap to resist vibrational loads from modern engine designs. Continuous torque capacity reaches 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options cover a wide range of hydraulic pump configurations. The 871 is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
