The Chelsea 871XJFJP-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 Nm) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options give this PTO broad application flexibility across fire and rescue, refuse, truck crane, and pumper cleaner equipment. The compact housing minimizes clearance concerns, and a ductile iron bearing cap is 117% stronger than the gray iron cap used in the predecessor 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear.
