Chelsea part number 871XCFJP-H3RS or 871XCFJPH3RS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. Nine speed ratios and thirteen output options give this series a wide application range covering fire and rescue, truck cranes, pumper cleaners, and refuse trucks. The compact housing reduces installation clearance conflicts, and a ductile iron bearing cap rated 117% stronger than gray iron improves durability.
