The Chelsea 871XAQTP-B3RK is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 Nm) with no derating required for continuous duty. The compact housing is engineered to reduce clearance issues, and the ductile iron bearing cap is 117% stronger than the gray iron predecessor used in the 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and combats vibration from modern engine designs. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options. Part number 871XAQTP-B3RK or 871XAQTPB3RK is sold by Pro Gear and Transmission.

Additional Information
The Chelsea 871 Series replaces the earlier 870 Series PTO. Key upgrades include the ductile iron bearing cap and the o-ring sealing configuration between the housing and bearing cap. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand options in a single platform: Wet Spline (extends PTO and pump shaft life), SmartStart (reduces shock load at start-up), and Quiet Gear. Nine speed ratios and thirteen output options are available across the series. Electronic Overspeed Control (EOC) is available to protect driven equipment. Typical markets 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.
