The Chelsea 871 Series Power Take-Off Assembly, part number 871XFFJP-D5AB or 871XFFJPD5AB, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series replaces the popular 870 Series with several structural upgrades: a ductile iron bearing cap rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap to reduce vibrational effects and improve clamp load. Continuous torque capacity reaches 670 lb-ft (908 N-m), with no derating required for continuous duty. Nine speed ratios and thirteen output configurations provide broad installation flexibility. The 871 is the only Chelsea PTO to offer all three premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
The 871 Series directly replaces the Chelsea 870 Series PTO. Applicable Parker Chelsea reference documents include the 267/281/288/871/878 Series Owner's Manual and the 871 Series Parts List (HY25-2871-M1/US).
