The Chelsea 871 Series Power Take-Off, part number 871XEFJP-B3RY or 871XEFJPB3RY, is a 10-bolt PowerShift (hydraulic) PTO engineered for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine available speed ratios and thirteen output options give upfitters the flexibility to match a wide range of driven equipment. A ductile iron bearing cap, rated 117% stronger than gray iron, pairs with an O-ring sealing configuration between the housing and bearing cap to resist the vibrational loading common in modern engine designs. Optional Wet Spline lubrication, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) round out the feature set. The 871 Series directly replaces the Chelsea 870 Series PTO. Call us to confirm proper fit for your application.
