The Chelsea 871XDFJP-G3XV or 871XDFJPG3XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmissions. The 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 this unit flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane applications. A ductile iron bearing cap rates 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-related damage and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the 871 Series. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm proper fit for your application.
