2.1 Checking Walterscheid coupling ball80: (see Fig. 3)
- Place the corresponding measuring range of the gauge (marked „ball 80“) onto ball80 in driving direction. The gap between the gauge and the edge of the ball shows the degree of wear. The smaller the gap, the closer the ball is to its wear limit. Nominal dimension ball 80: 80 mm, wear limit: 78.5 mm.
- The ball 80 has reached the wear limit when the gauge completely encloses the ball.

2.2 Checking the Walterscheid calottes 80 mm: (see Fig. 4)
- Place the corresponding measuring of the gauge (marked calotte) into the calotte. Use the flashlight to light up the inner zone of the calotte. The gap between the gauge and the surface of the calotte indicates the wear limit. The smaller the gap, the closer the calotte approaches its wear limit. Nominal dimension: 80 mm, wear limit: 81,5 mm.
- The spherical cap has reached the wear limit when the gauge touches the center of the spherical cap.

3. Inspection/Maintenance of PL-KK80 special tool (see Fig. 5):
For daily use, it is recommended that the individual test areas of the Walterscheid PL-KK80 special tool are checked once a year using appropriate measuring equipment in accordance with the dimensions in Fig. 5. Depending on the actual number of uses, this period can be extended to 60 months. If the deviations are more than 0.1 mm, the test gauge must be replaced.
