| 1. Before installation of new piston rings check a gap in the lock of a piston ring. |
2. Arrange pistons and piston rings according to cylinders in which they will work. |
| 3. Install the top sealing ring in the first cylinder and the bottom of the piston push it in the cylinder to the cylinder basis. |
| 4. Using the probe, measure a gap in the ring lock. |
| 5. Repeat process of measurement with the ring established in the top part of the cylinder and compare results of measurement to technical requirements. |
| 6. Repeat operation of check for each ring in the first cylinder, then for rings in other cylinders. |
| 7. Establish piston rings on pistons in the same way, as well as at removal. |
|
|
| 8. First of all the oil scraper ring which consists of three separate elements is established. Establish a dilator of an oil scraper ring in a piston flute. |
9. Then consistently establish the top and lower oil scraper rings.
|
| 10. Establish a compression ring No. 2 so that the tag at an end face of a ring was directed up. Do not mix the first and second compression rings as they have various profile. |
|
11. After installation of piston rings on the piston check ease of movement of a piston ring in a piston flute. |
