The ACH3SN Reich Arcusaflex Drive Coupler Kit is a complete coupling assembly for the ACH3SN configuration, including mixed hub types (taper-lock “S” and standard keyway “N”) with the elastomeric element. This kit provides everything needed for a complete coupling replacement. Ordering the complete kit ensures both hub types and the correct element are included, which is critical since the “S” and “N” hubs are different components that must match the shaft connections on each side.
Follow the specific installation procedure for each hub type – taper-lock hubs require a defined torque sequence on the locking hardware. Verify alignment after installing both hubs before startup.
