The Chelsea 871LBQTW-B5TY or 871LBQTWB5TY is a Power Take-Off assembly from Chelsea's 871 Series, built for demanding hydraulic and auxiliary drive applications. Torque capacity reaches 670 lb-ft (908 N-m), and the unit offers nine speed ratios spanning low and high ranges along with thirteen output configurations, giving fleet and spec shops considerable flexibility. Ductile iron bearing caps are rated 117% stronger than gray iron. An O-ring sealing arrangement reduces the effects of vibration and maintains clamp load more consistently than standard seals. A wet spline pump flange protects both the PTO output and the pump shaft from premature wear. Optional Electronic Overspeed Control (EOC) safeguards connected equipment, and a SmartStart option is available to reduce shock loading at engagement. Call us to confirm proper fit for your application.
