5.19. Piston rings - installation

1. Before installation of new piston rings it is necessary to check up a backlash in their joints.
It is meant that the backlash between a ring and a platform of a landing flute is checked already up and corresponds to norm.
2. Spread out pistons in gathering with rods and new piston rings in such order that the set of rings corresponded to the cylinder on which the backlash 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 its axes (photo). The ring should be in the bottom part of the cylinder, in the position corresponding to the bottom dead point.
4. Measure щупами a backlash and compare result to standard value (photo). If the backlash is more or less established once again check up correctness of selection of rings.
5. If the backlash is too small, file end faces (photo).
6. The backlash in a joint of a ring to 1 mm is supposed.
7. Believe a backlash in each ring.
8. Establish rings on the piston, having begun with маслосъемного. 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 ma-slosemnyh disks to use the adaptation for clothing of rings it is impossible, as their breakage is possible

19.10а Cross-section profiles of rings 1. Marks

9. After installation of all details маслосъемного rings 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 correct orientation of a ring. Do not mix top and bottom компрессионные a ring, as at them various cross-section profiles.
