Installation of piston rings


1. Before installation of new piston rings it is necessary to check gaps in their locks. It is meant that lateral gaps of landing of rings in flutes of pistons are already checked and correspond to norms (see. Check of a condition of components of shatunno-piston group).
2. Spread out shatunno-piston assemblies with sets of rings on a working surface of a workbench. From this point each set of rings will be rigidly adhered" to the piston. Now it is possible to start measurement of gaps in locks of rings.

3. Fill the top (first) kompressionny ring in the first cylinder of the engine and level it perpendicularly, having pushed down the piston bottom (see an accompanying illustration). The ring should appear around the bottom border of a working course of rings in the cylinder.

4. Define size of a gap of the lock of a ring with the help щупа lezviyny type (see an accompanying illustration). The edge (I) щупа should slip hardly in the lock. Compare result of measurement to requirements of Specifications. If the gap leaves in this or that party out of limits of an admissible range, first of all once again make sure that did not mix a ring.

5. If gap it is too small, it is possible to expand it with a way of boring by a file with small tooth. Clamp a rectangular file in a vice, then put on a ring the lock a file so that the end of the last appeared in a ring circle. Slowly pull a ring on itself, removing excess of metal from its end faces in the lock. Having reached till the file end, remove a ring, again check a gap, in case of need repeat procedure.

At all do not push a ring from itself on a file as thus edges of the lock will meet and the risk of destruction of metal is great.

6. The excessive size of a gap is not a crime if does not exceed the limit stipulated in Specifications. Still make sure that the acquired sets of rings answer according to the characteristics to the engine of your car.
7. Repeat procedure for the remained rings (the second kompressionny and maslosjemny) the piston of the first cylinder, then for all other pistons. Remember that now each set of rings "is unequivocally adhered" to the piston on which it should be established.
8. Having checked and having modified properly gaps in locks of rings, it is possible to start their putting on on the pistons.

9a. The first on the piston the maslosjemny (bottom) ring puts on. On the majority of models the maslosjemny ring consists of three separate sections. At first fill in the bottom flute of the piston a spring dilator of a maslosjemny ring (see an accompanying illustration). If the dilator is equipped with an antirotational uvula, track, that the last got to reciprocal drilling in a piston flute.

9b. Now establish in a flute the bottom working section of a ring. In order to avoid casual damage of working sections of a maslosjemny ring do not use for their installation any tool, – simply get in a flute under/over a dilator at first one end of section, densely press it a finger and, moving on ring perimeter, fill the rest (see an accompanying illustration). In the last turn the top working section of a ring is established.

10. Having planted in the bottom flute of the piston all three components of a maslosjemny ring, check freedom of rotation (sliding in a flute) the top and bottom working sections.
11. The second kompressionny ring is established to the following. The ring should be established by marking up (to the piston bottom).

Strictly follow instructions of manufacturers of rings which are usually printed on set packing. Do not mix the second kompressionny ring with first (top) – they have various cross-section section.

12. Having used the special landing tool and having tracked, that the ring was turned by marking up, plant it in an average flute on the piston (see an accompanying illustration). Try not to plant the ring lock more than it is really necessary for its free putting on on the piston.

13. Operating in a similar manner, establish the first (top) kompressionny ring (marking up). Try not to mix the top ring with the second.
14. Repeat procedure, having serially equipped with rings all pistons.
