The Chelsea 871 Series Power Take-Off (PTO), part number 871XGQTP-D5SV or 871XGQTPD5SV, is a 10-bolt PowerShift (hydraulic) unit designed for Allison transmissions. The 871 Series delivers continuous torque capacity 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 a wide fit across demanding vocational work including fire and rescue, refuse, truck cranes, and pumper/cleaner bodies. The ductile iron bearing cap is 117% stronger than gray iron, and the O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series is the only Chelsea PTO offering all three of Chelsea's solutions: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
