Installation Instructions

  1. Assure that the misalignment between shafts is within the coupling's ratings.
  2. Slide a hub onto each shaft to be joined with the drive tenons facing each other.
  3. Fully tighten the screw(s) on the first hub to the recommended seating torque.
  4. Insert a spider into the jaws of one hub until the raised points contact the base of the hub.
  5. Insert the jaws of the second hub into the spider openings until the raised points contact the base of the second hub. Some force will be required to insert the second hub. This is normal.
  6. Assure that a gap is maintained between the two hubs so there is no metal to metal contact. Fully tighten the screw(s) on the second hub to the recommended seating torque.
