The Chelsea 871XAFJP-B3RF is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. This series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous duty operation. Nine speed ratios and thirteen output options give installers wide flexibility. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. Optional Wet Spline, SmartStart, and Quiet Gear configurations make the 871 Series the only Chelsea PTO to offer all three of those solutions in a single compact housing. Common markets include fire and rescue, refuse, truck cranes, and pumper-cleaner trucks. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces the earlier Chelsea 870 Series PTO. Applicable Parker reference documents include the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and 871 Series Sales Literature. The series is suited for fire and rescue apparatus, refuse trucks, truck cranes, and pumper-cleaner vehicles. Electronic Overspeed Control (EOC) is available to protect driven equipment from overspeed damage.
