The Chelsea 871XBFJP-G5RS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give this PTO broad application flexibility across fire and rescue, refuse, truck crane, and pumper/cleaner work. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap help resist the vibrational loads produced by modern engine designs. The compact housing profile reduces clearance conflicts during installation. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces the Chelsea 870 Series PTO. This assembly incorporates all upgrades introduced with the 871 Series platform, including the ductile iron bearing cap and improved O-ring seal interface. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand options together: Wet Spline, SmartStart, and Quiet Gear. Applicable markets include fire and rescue, refuse collection, truck cranes, and pumper/cleaner equipment.
