3.4.23. Installation of pistons and rods

Check of a lubricant gap of shatunny bearings

1. Clean the top loose leaf of the bearing of a rod and establish it on a rod. Lubricant openings of a rod and the loose leaf should be combined.
2. Clean the second loose leaf and establish it in a rod cover.

3. Arrange trailer gaps of piston rings as is shown in drawing.
1. Gap of the top maslosjemny ring
2. Gap of a broad ring
3. Gap of the bottom maslosjemny ring
4. Gap of the top kompressionny ring
5. Porshnevy finger
6. Gap of the second kompressionny ring
4. Grease pistons and rings and compress piston rings by means of the compressor of piston rings.
5. Turn a cranked shaft so that the shatunny bearing of the first cylinder was in the family way the bottom dead point, and grease cylinder walls.
6. Check, that the mark from above the piston was turned forward.
7. Press on the piston and establish it in the cylinder.
8. For measurement of a lubricant gap it is possible to use an internal micrometer or other special device, but the most exact and easy method is to use a special plastic measuring instrument.
9. After piston installation in the cylinder, tighten bolts of covers of rods, and check a lubricant gap of the shatunny bearing similar to check of a lubricant gap of radical bearings.
10. If size of a gap do not correspond demanded, possibly, loose leaves of the wrong size are established.

Final installation of pistons and rods

1. Remove all traces of plastic. Check, that the surface of loose leaves was absolutely pure, and grease them with engine oil.
2. Establish a rod on a shaft neck, establish a cover of a rod and tighten nuts till the demanded moment of an inhaling.
3. Installation of other rods is carried out similarly.
4. After installation of all rods turn a cranked shaft several times and check ease of a course.
5. Check axial люфт rods.
