The Chelsea 871XBFJP-G5XV or 871XBFJPG5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), and the series supports continuous duty without derating. Nine speed ratios and thirteen output configurations give this PTO wide application flexibility across fire and rescue, refuse, pumper cleaner, and truck crane work. A ductile iron bearing cap delivers 117% greater strength than gray iron, and an o-ring sealing configuration between the housing and bearing cap reduces vibration effects and improves clamp load. The compact housing minimizes clearance concerns at installation. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces Chelsea's popular 870 Series PTO. Upgraded features include the ductile iron bearing cap and o-ring sealing configuration, both aimed at reducing vibration damage from current and future engine designs. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand solutions together: Wet Spline, SmartStart, and Quiet Gear. Electronic Overspeed Control (EOC) is available to protect driven equipment. SmartStart reduces shock load at start-up for applicable installations.
