The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D5BV or 871XAFJPD5BV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmission applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options give this unit broad coverage across fire and rescue, pumper/cleaner, refuse, and truck crane installations. A ductile iron bearing cap - 117% stronger than gray iron - and an o-ring sealing configuration between the housing and bearing cap reduce the vibrational stress associated with modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are all available on the 871 Series. The compact housing minimizes clearance concerns during installation. Call us to confirm proper fit for your specific application.
