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. Rotate the hubs on the shaft so the drive tenons are located 90° from each other.
  4. Place a torque disk so one groove fits over the drive tenons of a hub and center the disk by hand.
  5. Insert a shim with the thickness of the coupling's axial motion rating into the groove of the torque disk.
  6. Slide the tenons of the second hub into the mating groove in the disk until it touches the shim stock.
  7. Fully tighten the screw(s) on each hub to their recommended seating torque.
  8. Remove the shim stock to leave a small gap between the top of the drive tenons and the torque disk to allow for axial movement.
