The Chelsea 871 Series Power Take-Off, part number 871XGFJP-B3RS or 871XGFJPB3RS, is a 10-bolt PowerShift (hydraulic shift) PTO engineered for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty use. Nine speed ratios and thirteen output options give technicians a wide range of installation flexibility, while the compact housing keeps clearance issues to a minimum. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational stress. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform. Typical markets include fire and rescue, truck cranes, pumper cleaner, and refuse equipment. Call us to confirm proper fit for your application.
