Installation of piston rings


1. Make sure of correctness of landing of pistons on the rods, and piston rings in the flutes (see Has undressed Removal, check of a condition and installation of shatunno-piston assemblages).
2. Before installation of rings on pistons it is necessary to check up size of backlashes in their locks.
3. Spread out piston assemblages and complete sets of their rings on a pure working surface. The block of cylinders lay sideways on a workbench, having provided access both to its top party, and to bottom.
4. Fill top компрессионное a ring of the corresponding piston in the first cylinder of the engine. The piston bottom push a ring in the bottom part of the cylinder. Take the piston.

5. Щупом лезвийного type measure a backlash in the ring lock - a demanded thickness the edge (Specifications see) should slip hardly between face surfaces of a ring in its lock. Before to reject a ring, make sure that have not mixed it with the bottom. Repeat procedure for the remained rings.

6. At use of firm new piston rings probability of that backlashes in their locks will be too small is smallest - remember that смыкание 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 backlash, by gradual grinding of end faces of a ring about clamped in a vice надфиль - densely put on a ring the lock on надфиль and pull it on itself (at all from itself in order to avoid risk of destruction of a ring at смыкании the lock). If the result of measurement exceeds admissible value (that in case of new rings is rather improbable) before забраковывать a ring, make sure that have got the complete set of rings of your car of a standard size corresponding to the engine.

7. After end of check and updating of backlashes 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. In the flute on the piston the spring dilator bottom (маслосъемного) rings first of all refuels, the trace establishes its both lateral sections. We will notice that both a dilator, and lateral sections маслосъемного rings can be established by any party upwards. The second and top компрессионные rings have various cross-section sections and can be distinguished from each other on the marks put from their top party. Track, that rings were established on the piston by marks upwards.

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

In case of different interpretations installation of rings should be made according to instructions of their manufacturers.
