Installation of compression rings

On rings there are tags (1(2)T or 1 (2)N for 4-cylinder engines i1 (2) R or T1 (t2) 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 has to be in the lower part of the cylinder, in the situation corresponding to the lower dead point.
2. Measure a gap in joints. If the gap is too small, replace a ring, it is forbidden to file end faces.
3. Establish rings on the piston, having begun with the oil scraper. Establish a divider / dilator in a flute.
4. Be convinced available a pin (if it is provided) and establish the lower and top disks. At installation of oil scraper disks it is impossible to use the adaptation for clothing of rings as their breakage is possible.
5. Be convinced that the top and lower disks are freely turned in a flute. Establish average and top rings (see rice. Installation of compression rings). Tags on rings have to be turned to the piston bottom. Establish rings on other pistons.
