The Chelsea 871 Series Power Take-Off, part number 871XCQTP-D3RY or 871XCQTPD3RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty operation. Nine speed ratios and thirteen output options give this unit a wide range of installation possibilities, while the compact housing is engineered to reduce clearance issues in tight installations. This PTO offers all three of Chelsea's signature options in a single unit: Wet Spline pump flange for extended shaft life, SmartStart to reduce shock load at start-up, and the Quiet Gear input option. Electronic Overspeed Control (EOC) protects driven equipment. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. Upgraded features include the ductile iron bearing cap and the O-ring sealing configuration between the housing and bearing cap. This is the only Chelsea PTO to offer all three high-demand options together: Wet Spline, SmartStart, and Quiet Gear. Common markets for the 871 Series include fire and rescue, truck cranes, pumper/cleaner trucks, and refuse applications. Parker reference documents for this series include the 267/281/288/871/878 Series Owner's Manual and the 871 Series Parts List (HY25-2871-M1/US).
