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