The Chelsea 871XCFJP-E5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 Nm) with no derating required for continuous-duty operation. Its compact housing is built to reduce clearance issues during installation, and multiple assembly arrangements support a wide range of mounting configurations. The ductile iron bearing cap is 117% stronger than the gray iron predecessor used in the 870 Series, and an o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. Nine speed ratios and thirteen output options make this series adaptable across fire and rescue, refuse, truck crane, and pumper cleaner applications.
