The Chelsea 871XBFJP-D5BC is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 Nm), with shaft power ratings of 64 HP at 500 RPM and 128 HP at 1,000 RPM. The compact housing is engineered to reduce clearance issues, and the ductile iron bearing cap is 117% stronger than the gray iron predecessor. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects. Output options span SAE B, SAE BB, and SAE C pump spline configurations, as well as companion flange and DIN flange variants. The 871 Series supports nine speed ratios and thirteen output options, with Wet Spline, SmartStart, and Quiet Gear options available across the line. Available from Pro Gear and Transmission.

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