| 1. To clear of dust and dirt press and conducted disks, and also a working surface of a flywheel. |
| 2. To examine the conducted disk. Cracks on details of the conducted disk are not allowed. To check wear of frictional slips. In case heads of rivets are deepened on distance less than 0,2 mm, the surface of frictional slips is greasy or rivet connections, the conducted disk are weakened (or frictional slips) need to be replaced. To check reliability of fixing of damping springs in nests of a nave of the conducted disk, at the broken springs the disk needs to be replaced. To check a beating of the conducted disk if at visual survey its buckling is revealed. If the beating exceeds 0,4 mm (it is measured at distance of 2,5 mm from an external edge of a disk), the disk needs to be replaced. |
| 3. To examine working surfaces of friction of a flywheel and a press disk, having paid attention to absence deep risok, nadirs, zaboin, obvious wear tracks and an overheat. Weakening of rivet connections of details of a press disk is not allowed. With the specified defects knots are recommended to be replaced. To check a buckling of a press disk, having put a metal ruler to its working surface. If the probe 0,3 mm thick can be inserted in any place under a ruler, to replace press a disk with a casing assembled. |
| 4. External survey to estimate a condition of a diaphragm spring of a press disk. Places of contact of petals of a spring with the bearing of switching off of coupling have to be in one plane and not have obvious wear tracks. |
| 5. To check ease of movement in the axial direction of the conducted coupling disk on vents of primary shaft. At the complicated movement to remove agnails from shlits. The radial side play of a disk on a shaft is not allowed. |
