3.1.2.11.2. Installation and check of backlashes in шатунных bearings


The prevention

The description concerns only шатунных bearings of the standard size. Repair шатунные loose leaves are not subdivided into dimensional groups.


New шатунные bearings steal up on the codes of dimensional group put on коленвале.

Codes of dimensional groups are put on 1st or on 4th cheeks коленвала.

To pick up loose leaves шатунных bearings it is necessary to learn dimensional group шатунной necks коленвала for the given cylinder, and then under the applied table to define the necessary loose leaf, being guided on colour marks which in the form of a point are put on a lateral surface of the loose leaf.

Backlash check in шатунных bearings

PERFORMANCE ORDER
1. Clear an external surface шатунных loose leaves and a surface расточек under loose leaves in rods and in covers of rods.
2. Insert on loose leaves and be convinced that ledges on bearing loose leaves have come into samples in a rod (marksman) and in a rod cover.
3. At installation of loose leaves it is forbidden to touch a working surface. Be convinced that the lubricant aperture in top шатунном the loose leaf was precisely combined with an aperture in a rod.
4. If backlash check is carried out with old loose leaves insert these loose leaves on former places.
5. The backlash in шатунных bearings can be checked up in two ways.
6. At backlash definition by the first way collect covers with rods and шатунными bearings, having tracked correctness of mutual orientation of these details.
7. Tighten nuts of covers with the set moment and measure internal diameter of each collected pair loose leaves. The backlash is defined as a difference of internal diameter collected шатунных bearings and diameter шатунной necks.
8. The second way (more exact) consists in application plastic калибровочной a wire.
9. Establish шатунные bearings, it is correct them сориентировав. On everyone шатунную a neck коленвала put on a piece калибровочной a wire.
10. Clear surfaces шатунных loose leaves and establish rods on corresponding necks коленвала. Establish covers шатунных bearings, сориентировав them on available labels, or labels put at dismantling.
11. Tighten nuts of covers. At a tightening change of position of a wire is not supposed, also it is not supposed проворачивание коленвала.
12. Remove covers of rods, without supposing thus turn коленвала or displacement калибровочной a wire. Compare width of the flattened wire to a scale on packing and define a backlash in radical bearings.
13. If the backlash differs from standard wrong selection шатунных loose leaves (or their raised deterioration can be the reason if the loose leaves which were in operation) were checked.
14. Before coming to a conclusion about necessity of replacement of loose leaves be convinced that between surfaces of covers or rods and the loose leaf at measurement there was no dirt or oil.
15. If the width of the flattened wire from one edge is more, it specifies on конусность шатунной necks.
16. If the backlash differs from norm at measurements with old loose leaves repeat measurements with new loose leaves.
17. If and with new loose leaves the backlash exceeds norm it is necessary to address for consultation in car-care centre service. Repolishing шатунных necks коленвала and replacement of loose leaves repair can be necessary.
18. If necessary get loose leaves of corresponding dimensional group and repeat procedure of measurement of a backlash in шатунных bearings.
19. Upon termination of cautiously remove the wire rests.

Installation of shatunno-piston group

The further description is conducted in that assumption that коленвал is already established.

PERFORMANCE ORDER
1. Be convinced of correctness of installation шатунных bearings.
2. If new bearings wash out them in kerosene are established.
3. Dry wipe rods and bearings.
4. Grease cylinders, pistons and rings, then lay out pistons in gathering with rods in that sequence in which these details will be established on the engine.
5. Assemblage begin with 1st cylinder. Be convinced of correct arrangement of joints of piston rings (cм. Subsection 3.1.2.13) also compress rings the special adaptation.
6. Insert the piston in gathering with a rod into the first cylinder. Сориентируйте the piston so that the label on the piston bottom (in the form of an arrow or line) has been turned towards a forward cover. Slightly knock on the piston with the handle of a hammer or wooden бруском that the piston has come into the cylinder and the piston bottom it was made even to a demountable plane of the block of cylinders.
7. Be convinced that шатунные loose leaves are established correctly and plentifully grease loose leaves and шатунную a neck коленвала.
8. Cautiously, not to damage a cylinder surface, draw a rod to a neck коленвала.
9. Put on a cover of a rod with the loose leaf and tighten nuts by hand. Keep in mind that planes on a rod and on a rod cover on which labels are put, should be combined (it means that adjusting ledges шатунных bearings are located opposite each other).
10. Tighten nuts шатунных covers with the moment of 1st stage of an inhaling with the help динамометрического a key and a face head. Then tighten nuts on a corner of 2nd stage of an inhaling, or tighten with the moment of 2nd stage.
11. Check up rotation freedom коленвала. If new details appreciable constant resistance to rotation коленвала should be felt are established, however коленвал should be turned smoothly, without jammings.
12. Similarly establish other pistons and rods.
13. Establish a head of cylinders, chains of cam-shafts and the oil pallet.
