4.26. Pistons and rods - installation and check of a lubricant backlash of the bearing

1. Before installation of pistons and rods clear cylinders and establish a cranked shaft into place.

2. Remove a cover of the first rod.

3. Clear the new loose leaf and establish it on a rod. Yet do not grease the loose leaf.

4. Clear the second loose leaf and establish it in a cover.

25.5 Turn piston rings how it is shown in drawing, before installation of pistons and rods in the engine 1. A backlash of the first компрессионного rings 2. A backlash top маслосъемного rings 3. A backlash of the second компрессионного a ring and a broad ring 4. To a pulley of a cranked shaft 5. A backlash bottom маслосъемного rings

5. Turn piston rings so that their backlashes settled down under a corner in 90 ° to each other (25.5).

6. Put on pieces of a rubber hose rod bolts.

7. Grease pistons and rings with pure engine oil and establish the compressor of piston rings on the piston.

8. Turn a cranked shaft so that the neck of the first cylinder was in the bottom dead point, and grease cylinder walls.

25.9 Mark in a piston head should be turned aside газораспределительного a belt

9. Check up, that the mark from above the cylinder (25.9) has been turned aside газораспределительного a belt, and establish the piston and a rod in the cylinder so that the compressor of piston rings concerned a surface of the block of cylinders.

10.  Check up, that the compressor of rings densely adjoined to a surface of the block of cylinders.

25.11 Piston can be lowered deep into the cylinder by means of the wooden handle

11. Tapping on the piston the handle of a hammer (25.11), lower the piston deep into the cylinder and establish a rod

On a neck of a cranked shaft.

12. Before definitive installation of a cover of a rod it is necessary to check up a lubricant backlash of the bearing.

25.13 Put strips of film Пластигодж on each of шатунных necks, in parallel an axis of a cranked shaft

13. Cut off a piece of film Пластигодж hardly more shortly, than width шатунного the bearing and put it on шатунную a neck, in parallel an axis of a cranked shaft (25.13).

25.14 Combine the figures specifying number of the cylinder, and ledges on the loose leaf at installation of covers of rods 1. N the cylinder 2. Ledges and flutes

14.  Clear a surface of the loose leaf of a cover and establish a cover on a rod (25.14).

15. Establish nuts and tighten them till the demanded moment of an inhaling in three stages.

16. Turn off nuts, and accurately remove a cover.

25.17 Measure width of film Пластигодж for definition of size of a lubricant backlash of the bearing

17. Compare width of the crushed film to the special scale applied on a film, for check of size of a lubricant backlash (25.17).

18. If the backlash size differs from demanded value, establish  loose leaves of other  size. Check up, that between loose leaves and a rod or a cover there was no dirt or oils. If the crushed

The film width from one end, possibly, a neck of a cranked shaft has got the conic form.

19. Remove traces of film Пластигодж.

20. Check up, that a surface of loose leaves, rods and covers were ideally pure, then grease loose leaves with an equal layer молибденовой greasings.

21. Establish a rod on a neck, establish a cover and tighten fixing nuts till the demanded moment of an inhaling in three stages.

22. Similarly establish the remained pistons and rods.

23. After all pistons and rods will be established, turn a cranked shaft some hand and check up, that nothing stirred to its rotation.

24. Check up axial люфт rods.
