3.2.2.12. Piston rings

The scheme of installation of rings on the piston

1. For updating SR20DE

2. For updatings SR20Di and SR20De


Arrangement of joints of piston rings

1. Top компрессионное a ring

2. A dilator маслосъемного rings

3. To a forward part of the engine

4. Bottom компрессионное a ring

5. The bottom disk маслосъемного rings

6. The top disk маслосъемного rings

Installation

PERFORMANCE ORDER
1. Before installation of new piston rings it is necessary to check up a backlash in their joints. Spread out pistons collected with rods and new piston rings in such order that the set of rings corresponded to that cylinder in which the backlash will be measured in a joint and in which checked rings will be established.
2. Insert into the first cylinder the top ring and push the piston bottom inside so that the ring in the cylinder became perpendicular its axes. Push a ring on such depth on which the edge of a skirt of the piston will be made even to a demountable plane of the block of cylinders then get the piston.
3. Measure a backlash щупом and result compare with standard, specified in subsection 3.2.1.1.
4. If the backlash is too small (that it is improbable if the rings which have been let out Nissan) it is necessary to expand it are established. Otherwise because of смыкания rings at engine work there will be serious breakages. Is better necessary pick up new rings with a standard backlash in a joint. At the worst it is possible to expand a backlash, accurately having filed end faces of a joint of a ring thin надфилем. For this purpose clamp надфиль in a vice with soft sponges, get a ring so that joint end faces have appeared on both parties надфиля, and, slowly moving a ring, remove an excessive material. Keep in mind that the ring very fragile and can easily break.
5. It is improbable that the backlash in new rings will be too big. If the backlash above norm be convinced that a ring corresponds to the given engine and dimensional group of the cylinder.
6. Repeat procedure for each ring of the first cylinder, and also for rings of other cylinders. Rings and the pistons corresponding to the same cylinder, store together.
7. After selection of rings, measurements and updatings of a backlash of a ring can be established on pistons (fig. the Scheme of installation of rings on the piston see).

The prevention

Always observe the instruction of the manufacturer of rings as different manufacturers recommend different procedures of installation of rings for the piston. Do not mix top and bottom компрессионные ring which have different cross-section sections.


8. By the first it is established маслосъемное a ring (the lowermost on the piston). This ring consists of three details. Establish in a flute a dilator.
9. Then between a dilator and platforms of a flute of the piston establish one after another the top and bottom disks маслосъемного rings.
10. The following establish bottom компрессионное a ring.

The prevention

Top and bottom компрессионные rings differ on cross-section section.


11. Before installation correctly сориентируйте a ring (ориентационные labels on компрессионных rings should be turned upwards) and establish a ring in an average flute on the piston, thus it is forbidden to move apart a ring too strongly.
12. Similarly establish top компрессионное a ring, it is preliminary correct it сориентировав. If the ring has symmetric section arrange it so that the identification label (it is specified by an arrow) has been turned upwards.
13. After installation of rings on the piston place joints according to fig. Arrangement of joints of piston rings.
14. Having repeated these procedures, establish rings on other pistons.
