The Chelsea 871XFFJP-B3SV or 871XFFJPB3SV is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The series carries a continuous torque rating up to 670 lb-ft (908 N-m), and the compact housing is built to reduce clearance conflicts during installation. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap work together to counter the vibrational effects common with modern engine designs. The 871 Series is the only Chelsea PTO to combine all three premium options: Wet Spline, SmartStart, and Quiet Gear. Nine speed ratios and thirteen output configurations give this unit broad application flexibility across fire and rescue, truck cranes, pumper-cleaner, and refuse equipment. Call us to confirm proper fit for your specific transmission and installation.
The Chelsea 871 Series replaces the earlier 870 Series PTO. Applicable Parker 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.
