The Chelsea 871XAKVP-B5XV or 871XAKVPB5XV is a 10-bolt, hydraulic PowerShift Power Take-Off from the 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating of 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 wide range of installation requirements, while the compact housing reduces clearance issues common in tight installations. This assembly includes a ductile iron bearing cap rated 117% stronger than gray iron, an O-ring sealing configuration to improve clamp load and reduce vibration-related wear, and a Wet Spline pump flange to extend PTO and pump shaft service life. Electronic Overspeed Control (EOC) and an optional SmartStart feature are available within the series to protect driven equipment and reduce shock loads at start-up. Call us to confirm proper fit for your specific transmission and application.
