The pressure rod of the working cylinder has a different diameter between the piston and the clutch release lever. Depending on the size of the rod's protrusion from the flange of the working cylinder, the diameter of the rod changes, and the degree of wear of the clutch slave disk linings is determined by the penetration of the gauge to a certain length. The gauge can be made independently from a steel plate 0.6–0.8 mm thick and 15 mm wide (Fig. 10.2). If the gauge marks are not visible behind the flange of the working cylinder, then the wear of the clutch slave disk is insignificant.
Sequence of works
1. Place the vehicle on stands and remove the lower engine guard.

2. Insert the test gauge 4 (Fig. 6.2) into the groove in front of the working cylinder flange until it stops.
3. If the marks are visible (shown by arrows) along the edges of the F gauge, the wear of the linings is close to the limit, that is, about 2 mm remains from the original 3.8 mm, the clutch will begin to slip in the future. If the gauge marks are not visible behind the flange of the working cylinder, the driven clutch disc is in good condition.
