The Chelsea 871 Series Power Take-Off, part number 871XGFJP-D5BC or 871XGFJPD5BC, is a 10-bolt PowerShift (hydraulic) PTO 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, making it well suited for demanding vocations including fire and rescue, refuse, truck cranes, and pumper/cleaner equipment. Nine speed ratios and thirteen output options cover a wide range of installation requirements. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-induced wear and improves clamp load. The 871 Series is the only Chelsea PTO offering all three of Chelsea's high-demand solutions: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
