The Chelsea 871XBKVP-D3RY or 871XBKVPD3RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. This series carries continuous torque ratings up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. The compact housing keeps clearance issues to a minimum, while nine available speed ratios and thirteen output options give it broad application flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane installations. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces the damaging vibrational effects associated with modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are available within this series. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. Applicable Parker Chelsea documentation includes the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and the 871 Series Sales Literature. This unit is also referenced under part number SP871XBKVP-D3RY. Typical market applications include fire and rescue apparatus, refuse trucks, pumper/cleaner units, and truck cranes.
