3.3.16. Installation of piston rings

GENERAL INFORMATION

Arrangement of piston rings on the piston

1. Oil scraper ring

2. Average sealing ring

3. Top sealing ring


Before installation of new piston rings check a gap in the ring lock.

PERFORMANCE ORDER
1. Arrange pistons and piston rings according to cylinders in which they will work.
2. Install the top sealing ring in the first cylinder and the bottom of the piston push it in the cylinder to the cylinder basis.

Prevention

The top and average sealing rings are various, an external surface of an average ring conical.


3. Using the probe, measure a gap in the ring lock.
4. Repeat process of measurement with the ring established in the top part of the cylinder, and compare results of measurement to specifications (see subsection 3.3).
5. If a gap too small, it it is necessary to increase, soshlifovyvy ring end faces.
6. If a gap in the ring lock too big, check correctness of compliance of rings to the engine.
7. Repeat operation of check for each ring in the first cylinder and then for rings in other cylinders.
8. Install piston rings on pistons in the same way, as well as at removal. At assembly of an oil scraper ring at first insert a spring and from above on a spring establish a ring so that the lock of a ring was from the opposite side from the spring lock. Check that the average sealing ring is established by marking (a tag paint or the word "TOP") up (see rice. An arrangement of piston rings on the piston). Establish sealing rings so that their locks were displaced concerning the lock of an oil scraper ring on 120 ° in different directions. Do not mix the top and average sealing rings since they have various profiles.
