1. Make sure of correctness of landing of pistons on the rods, and piston rings in the flutes (see the Section Removal, check of a state and installation of conrod and piston assemblies).
2. Before installation of rings it is necessary to check the size of gaps in their locks for pistons.
3. Spread out piston assemblies and sets of their rings on a pure working surface. Lay the block of cylinders sideways on a workbench, having provided access both to its top party, and to lower.
4. Fill the top compression ring of the corresponding piston in the first cylinder of the engine. The bottom of the piston push a ring in the lower part of the cylinder. Take the piston.

5. Measure by the probe of lezviyny type a gap in the ring lock - the required thickness the edge (see Specifications) has to slip hardly between face surfaces of a ring in its lock. Before rejecting a ring, make sure that did not mix it with lower. Repeat the procedure for the remained rings.

6. When using company new piston rings the probability that gaps in their locks will be too small is extremely small - remember that the smykaniye of locks at thermal expansion of rings is fraught with jamming of the engine and its irreversible exit out of operation. In case of need it is necessary to correct a gap, by gradual grinding of end faces of a ring about the file clamped in a vice - densely put on a ring the lock a file and pull it on yourself (not from yourself in order to avoid risk of destruction of a ring at a lock smykaniye at all). If the result of measurement exceeds admissible value (that in case of new rings is very improbable) before rejecting a ring, make sure that got a set of rings of your car of a standard size corresponding to the engine.

7. After completion of check and correction of gaps in locks of all rings it is possible to start their clothing on the pistons. The technology of clothing of rings on the piston is similar applied to their removal. First of all the spring dilator of the lower (oil scraper) ring refuels in the flute on the piston, both of its side sections are established by a trace. Let's notice that both the dilator, and side sections of an oil scraper ring can be established by any party up. The second and top compression rings have various cross sections and can be distinguished from each other on the marking put from their top party. Track that rings were established on the piston by marking up.

8. Having finished installation of rings on the piston, check freedom of their rotation in the flutes, then develop locks under 120 ° to each other.

In case of discrepancies installation of rings has to be made according to instructions of their manufacturers.
