1. Before installation of rings on pistons it is necessary to check size of gaps in their locks.
2. Spread out piston assemblies and sets of their rings on a pure working surface.
3. Fill the top kompressionny 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 (15÷20 mm from the bottom cut).

Pay attention that kompressionny rings differ from each other, - the second is easy for distinguishing from top on step existence from the bottom party, besides, its external forming surface has an appreciable konusnost.

4. Take the piston, then shchupy lezviyny type measure a gap - the demanded thickness an edge (see. Specifications) should slip hardly between face surfaces of a ring in its lock.

5. Repeat procedure, having transferred a ring to the top section of the cylinder (at the end of a piston stroke), compare results of measurements to requirements of Specifications. If standard data are not provided, address for consultation to specialists of car-care center.

6. When using firm new piston rings probability of that gaps in their locks will be too small, is rather insignificant, - remember that the lock smykaniye at thermal expansion of a ring 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 itself (at all from itself in order to avoid risk of destruction of a ring at a lock smykaniye).
7. If the result of measurement exceeds admissible value (that in case of new rings is very improbable) before забраковывать a ring, make sure that got a set of rings of your car of a standard size corresponding to the engine.
8. Repeat procedure for the remained rings of the first piston, and also for rings of all other pistons. Do not forget that now each of the picked-up rings is strictly adhered to the concrete piston.
9. After completion of check and correction of gaps in locks of all rings it is possible to start their clothing on the pistons.

10. The technology of clothing of rings on the piston is similar used at their removal. In the flute on the piston the spring dilator of the bottom (maslosjemny) ring first of all refuels, its both lateral sections (by locks under 180 ° to the dilator lock) afterwards are established. Let's notice that both the dilator, and lateral sections of a maslosjemny ring can be established by any party up. Afterwards the second kompressionny ring, and obligatory by an identification label in the form of an inscription of "TORAHS" up, and the step party down is established. The last the top kompressionny ring puts on. In summary it is necessary to develop kompressionny rings locks under 120 ° to the lock of a dilator of a maslosjemny ring.
Scheme of installation of piston rings
1 — Maslosjemnoye a ring
2 — the Second kompressionny ring
3 — the Top kompressionny ring

At installation of piston rings always strictly follow instructions of manufacturers enclosed to a set. Do not confuse the second kompressionny ring with top, - they differ on sections.
