1. Coupling selection should be in accordance with Magnaloy Performance Specifications and adjusted by the appropriate Service Factor for the application as discussed in the Selection Guide. Check shaft spacing to verify it is within the range given by dimensions "W" and "X" from Dimensional Specifications Chart
2. Position each hub on the proper size shaft - Magnaloy Couplings are machined to standard "Push fit" tolerances, if a tight fit exists, check shaft for burrs. Maximum benefits are obtained with the hubs positioned to allow complete shaft engagement within each bore. However, some equipment designs do not permit this condition in which case the hubs should be positioned to allow maximum shaft engagement.
3. Alignment - the equipment should be positioned so the coupling is within the recommended alignment conditions of 1° angular and .015 inch parallel. Perfect alignment can be obtained if a .005 inch feeler gauge will not fit beneath a straight edge placed across the large diameters at the top and side of the hubs.
4. Secure the equipment mounts and recheck alignment for movement.
5. Install the insert in the coupling positioning the hubs in light contact with the lip around the outside of the insert.
6. Before tightening set-screws, run the coupling and check for separation of the hubs. Recheck alignment and tighten set screws. When installing Magnaloy's Steel Brushed coupling, the clamp bolt must be tightened prior to tightening the keyway set-screw.
