Installation компрессионных rings

On rings there are labels (1 (2) Т 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 up a backlash in joints. For this purpose push a ring the piston bottom. The ring should be in the bottom part of the cylinder, in the position corresponding to the bottom dead point.
2. Measure a backlash in joints. If the backlash is too small, a ring replace, to file end faces it is forbidden.
3. Establish rings on the piston, having begun with маслосъемного. Establish in a flute a divider / a dilator.
4. Be convinced available a pin (if it is provided) and establish the bottom and top disks. At installation маслосъемных 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 (fig. Installation компрессионных rings see). Labels on rings should be turned to the piston bottom. Establish rings on other pistons.
