The Chelsea 871 Series Power Take-Off, part number 871XJQTP-D3AB or 871XJQTPD3AB, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options cover a broad range of installation requirements. A ductile iron bearing cap, rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap address the vibrational loads common in modern engine applications. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available. The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm the right configuration for your application.
The Chelsea 871 Series is the only Chelsea PTO to offer all three high-demand options in one platform: Wet Spline pump flange for extended PTO and pump shaft life, SmartStart to reduce shock load at start-up, and Quiet Gear input. Electronic Overspeed Control (EOC) is also available to protect driven equipment. Common markets for this series include fire and rescue, truck cranes, pumper/cleaner trucks, and refuse vehicles. The 871 Series supersedes the Chelsea 870 Series PTO. Part number 871XJQTP-D3AB is also referenced as SP871XJQTP-D3AB. Refer to the 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual for detailed application and installation guidance.
