All couplings

Dismounting:
  1. Loosen the clamp screw (E1) and remove the coupling.
  2. Use an appropriate tool that will not damage the coupling to pry the coupling halves apart.
Mounting:
  1. Slide a coupling half onto the shaft to the correct axial position.
  2. Using a torque wrench, tighten the clamp screw (E1) to 2Nm.
  3. Insert the elastomer ring and press the two coupling halves together.  Ensure that the fit length (A) is maintained at approximately 10mm.
  4. Mount the assembled coupling onto the second shaft and tighten the clamp screw (E1) to 2Nm.
