The Chelsea 871 Series Power Take-Off, part number 871XHFJP-K5XV or 871XHFJPK5XV, is a 10-bolt PowerShift (hydraulic shift) PTO 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 operation. Nine speed ratios and thirteen output configurations give installers broad flexibility across fire and rescue, truck crane, pumper/cleaner, and refuse applications. The ductile iron bearing cap is 117% stronger than the gray iron cap it replaces, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration effects from modern engine designs. The compact housing minimizes clearance concerns during installation. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's premium options - Wet Spline, SmartStart, and Quiet Gear - in a single platform. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces the earlier Chelsea 870 Series PTO. Upgraded features across the 871 Series include the ductile iron bearing cap, O-ring housing-to-bearing-cap seal, and availability of Wet Spline, SmartStart, and Quiet Gear options. Markets served include fire and rescue, truck cranes, pumper/cleaner trucks, and refuse vehicles. Reference documents for this series include the 267/281/288/871/878 Series Owner's Manual and 871 Series Parts List (HY25-2871-M1/US).
