The ACH3WN Reich Arcusaflex Drive Coupler Kit is a complete coupling assembly for the ACH3WN configuration. This kit includes the flanged “W” hub, standard keyway “N” hub, and elastomeric element as a matched set ready for installation.
This arrangement is common in SAE engine-mount configurations where the coupling connects a flanged engine output to a standard keyed shaft. The complete kit ensures all components are properly matched for the application.
During installation, verify that the flanged “W” hub interfaces correctly with the engine or equipment flange before proceeding with element and opposite hub installation. Align per manufacturer specifications and torque all fasteners properly.
