The Chelsea 871 Series Power Take-Off, part number 871XJQTP-D5AC or 871XJQTPD5AC, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output configurations give installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse body applications. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap resist vibrational stress from modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input are all available on this series. Call us to confirm the correct configuration for your truck.
