The Chelsea 871XAFJP-B5BC is a 10-bolt, hydraulic PowerShift Power Take-Off from the 871 Series, designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), with no derating required for continuous duty. Nine speed ratios and thirteen output options give this unit broad application flexibility across fire and rescue, truck cranes, refuse, and pumper-cleaner trucks. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce vibrational damage from modern engine designs. The compact housing minimizes clearance issues during installation. Call us to confirm proper fit for your specific transmission and application.
