The Chelsea 871XDFJP-B3XV or 871XDFJPB3XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 Series is rated for continuous torque 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. A ductile iron bearing cap delivers 117% greater strength than gray iron, while an O-ring sealing configuration between the housing and bearing cap reduces the effects of engine vibration and improves clamp load. The compact housing profile helps avoid clearance conflicts during installation. Call us to confirm proper fit for your specific transmission and application.
