Coupling

Check elastomer elements after running-in period and thereafter annually.

Check elastomer elements for wear

• Turn both coupling halves against each other (without torque) until stop position.
• Mark both halves (see figure below).
• Turn coupling halves (also without torque) in other direction until stop position.
• Measure radial distance between the two marks.
• Replace all elastomer elements if the distance exceeds 4 mm.
