The Chelsea 871 Series Power Take-Off, part number 871XGFJP-D5SV or 871XGFJPD5SV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series succeeds the 870 Series with a ductile iron bearing cap rated 117% stronger than gray iron and an o-ring sealing configuration between the housing and bearing cap to reduce vibrational effects and improve clamp load. Continuous torque capacity reaches 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options cover a wide range of applications including fire and rescue, refuse, pumper cleaner, and truck crane work. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
