The Chelsea 871XBFJP-D5SV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series is rated for continuous-duty operation with torque capacity up to 670 lb-ft (908 N-m). Its compact housing reduces clearance issues during installation, and multiple assembly arrangements expand mounting options. The 871 Series features a ductile iron bearing cap, 117% stronger than the gray iron cap used in the predecessor 870 Series, plus an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce vibrational effects. Nine speed ratios and thirteen output options accommodate a wide range of driven equipment. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear configurations.

Additional Information
The Chelsea 871 Series replaces the Chelsea 870 Series PTO. Key upgrades include the ductile iron bearing cap and the improved o-ring sealing configuration, both aimed at reducing vibrational damage associated with modern engine designs. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's premium options in one platform: Wet Spline (extends PTO and pump shaft life), SmartStart (reduces shock load at start-up), and Quiet Gear (reduced operating noise). Electronic Overspeed Control (EOC) is available to protect driven equipment. Common market applications for the 871 Series include fire and rescue, truck cranes, pumper cleaners, and refuse vehicles.Parts Manual: Chelsea 871 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
