Installation of kompressionny rings

On rings there are labels (1 (2) T or 1 (2) N for 4-cylinder engines и1 (2) R or Т1 (т2) for V6).


1. Before installation of new piston rings sort rings and check a gap in joints. For this purpose push a ring the piston bottom. The ring should be in the lower part of the cylinder, in the situation corresponding to the bottom dead point.
2. Measure a gap in joints. If the gap is too small, a ring replace, to file end faces it is forbidden.
3. Establish rings on the piston, having begun with the maslosjemny. Establish in a flute a divider / dilator.
4. Be convinced available a pin (if it is provided) and establish the bottom and top disks. At installation of maslosjemny disks to use the adaptation for clothing of rings it is impossible, as their breakage is possible.
5. Be convinced that the top and bottom disks are freely turned in a flute. Establish average and top rings (see fig. Installation of kompressionny rings). Labels on rings should be turned to the piston bottom. Establish rings on other pistons.
