The Chelsea 871XGQTP-D5XV or 871XGQTPD5XV is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, refuse, truck crane, and pumper/cleaner applications. 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 while reducing vibration-related wear. The compact housing height eases clearance constraints. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within this series. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm the correct configuration for your chassis and driven equipment.
