3-1-2-13-porshnevye-kolca.html Piston rings


1. Check up a backlash in joints of rings.
2. Spread out pistons collected with rods and new piston rings in such order that the set of rings corresponded to that cylinder in which the backlash will be measured and in which checked rings will be established.
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. Push a ring on such depth on which the edge of a skirt of the piston will be made even to a demountable plane of the block of cylinders then get the piston.
4. Measure a backlash щупом and result compare to the standard.
5. If the backlash is too small, accurately file ring end faces thin надфилем.
6. If the backlash above norm be convinced that a ring corresponds to the given engine and dimensional group of the cylinder.
7. Repeat procedure for each ring of the first cylinder, and also for rings of other cylinders. Rings and the pistons corresponding to the same cylinder, store together.
8. After selection of rings, measurements and updatings of a backlash of a ring can be established on pistons.

The prevention

Always observe the instruction of the manufacturer of rings as different manufacturers recommend different procedures of installation of rings for the piston. Do not mix top and bottom компрессионные ring which have different profiles.

9. By the first it is established маслосъемное a ring.
10. Establish in a flute a dilator.
11. Then between a dilator and platforms of a flute of the piston establish one after another the top and bottom disks маслосъемного rings.
12. Establish bottom компрессионное a ring.
13. Establish top компрессионное a ring, it is correct it сориентировав. If the ring has symmetric section arrange it so that the identification label has been turned upwards.
14. Place joints in conformity.
15. Establish rings on other pistons. Radical and шатунные bearings Start-up of the engine after major repairs
