The Chelsea 871 Series Power Take-Off, part number 871XEQTW-B3RS or 871XEQTWB3RS, is a 10-bolt PowerShift (hydraulic) PTO designed 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 speed ratios and thirteen output options cover a wide range of application requirements. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap address the vibrational stresses of modern engine designs. The compact housing height reduces clearance concerns during installation. Options include Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC). Call us to confirm proper fit for your application.
