1 Cylinder liner
2 Dial gage
3 Gage for inside diameters
4 Outside micrometer
A, B Measuring direction in the cylinder liner
I Measuring point above the reversing point area of the first piston ring (wear-free area)
II Measuring point at the reversing point area of the first piston ring (highest wear area)
| Check | ||
1 | Clean the cylinder liner (1) inside. | ||
2 | Check the cylinder liner running surface (1) | The running surfaces must not present signs of excessive wear and/or deformations. | |
| Indications for checking cylinder liner damages caused by penetration of impurities | ||
| Measuring | ||
3 | With the micrometer (4), set the dial gage (2) and the inside diameter measuring gage (3) to the diameter of the cylinder liner (1) | Install the dial gage with 5 mm pre-load. | |
| |||
Outside micrometer | |||
Gage for inside diameters | |||
4 | Measure the inside diameter of the cylinder liner (1) in the no-wear area (I) and set the dial gage scale (2) to “0”. | Measure at measuring point (I), above the reversing area of the first piston ring, in the directions (A) and (B). | |
5 | Measure the wear in the running surface of the cylinder liner (1), in the reversion area (II) of the first piston ring | Measure in the measuring point (II), area of highest wear, in the directions, longitudinal (A) and transversal (B). | |
