The Chelsea 871 Series Power Take-Off Assembly, part number 871XCFJP-B5AC or 871XCFJPB5AC, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options cover a broad range of application requirements, from fire and rescue to refuse and truck crane work. A ductile iron bearing cap rated 117% stronger than gray iron resists the damaging vibration characteristics of modern engine designs. The o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input are all available within this series. Call us to confirm proper fit for your application.
