The Chelsea 871XAFJW-D5RF is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series replaces the popular 870 Series PTO with several targeted upgrades: a ductile iron bearing cap rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap to reduce vibrational stress and improve clamp load. The compact housing keeps overall height down to aid clearance in tight installations. The series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 N-m). Nine speed ratios and thirteen output options give technicians broad configuration flexibility. The 871 Series is the only Chelsea PTO to offer all three premium options together: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
The Chelsea 871 Series is used in fire and rescue, truck crane, pumper cleaner, and refuse truck applications. This series is designed for continuous duty and requires no derating.
