5.19. Piston rings - installation

1. Before installation of new piston rings it is necessary to check a gap in their joints.
It is meant that the gap between a ring and a platform of a landing flute is already checked and corresponds to norm.
2. Spread out pistons assembled with rods and new piston rings in such order that the set of rings corresponded to the cylinder on which the gap will be measured.
3. Insert into the first cylinder the top ring and push the piston bottom inside so that the ring in the cylinder became perpendicular to its axis (photo). The ring should be in the lower part of the cylinder, in the situation corresponding to the bottom dead point.
4. Measure щупами a gap and compare result to standard value (photo). If the gap is more or less established, once again check correctness of selection of rings.
5. If the gap is too small, file end faces (photo).
6. The gap in a ring joint to 1 mm is allowed.
7. Believe a gap in each ring.
8. Establish rings on the piston, having begun with the maslosjemny. Establish in a flute a divider/dilator (photo). Be convinced available a pin (if it is provided) and establish the bottom and top disks. At installation of ma-slosjemny disks to use the adaptation for clothing of rings it is impossible, as their breakage is possible

19.5 Podpilivaniye of ring end faces

19. 8а Installation of a dilator of a mayelosjemny ring

19.10а Cross-section profiles of rings 1. Marking

9. After installation of all details of a maslosjemny ring be convinced that the top and bottom disks are freely turned in a flute.
10. Establish average and top rings. The label on an average ring should be turned towards the bottom of the piston (photo).

Always be guided by the instruction on packing of piston rings, ~ different manufacturers can have different designations of the correct orientation of a ring. Do not mix the top and bottom kompressionny rings as they have various cross-section profiles.
