The Chelsea 871XFQTP-D5XV is a 10-bolt, hydraulic PowerShift Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous-duty operation. Its compact housing is engineered to reduce clearance conflicts in tight installations, and the ductile iron bearing cap is 117% stronger than gray iron. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the effects of engine vibration. The 871 Series supports up to nine speed ratios and thirteen output options, making it a versatile fit across fire and rescue, refuse, pumper cleaner, and truck crane applications.
