The Chelsea 871 Series Power Take-Off, part number 871XFFJW-D5RY or 871XFFJWD5RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The compact housing keeps installation clearances manageable across multiple assembly arrangements. Continuous torque capacity for the 871 Series reaches up to 670 lb-ft (908 N-m), with no derating required for continuous-duty operation. 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 vibrational effects and improves clamp load. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand options: Wet Spline, SmartStart, and Quiet Gear. This unit is sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 871 Series replaces the Chelsea 870 Series PTO. Upgraded features center on reducing the damaging vibrational effects caused by modern engine designs. Common markets for the 871 Series include fire and rescue, truck cranes, pumper cleaner, and refuse applications. The 871 Series is the only Chelsea PTO to offer all three high-demand options simultaneously: Wet Spline, SmartStart, and Quiet Gear. Parker Chelsea documents available for this series include the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and the 871 Series Sales Literature.
