The Chelsea 871LEFJW-B5TZ or 871LEFJWB5TZ is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 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. 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 loads generated by modern engine designs. Nine speed ratios and thirteen output options cover a wide range of driven-equipment requirements. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your application.
