3.2.2.10.2. 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 or on a cheek коленвала near to a neck of 1st cylinder (from outside to a chain of a drive of cam-shafts), or on a cheek near to a neck of 4th cylinder (from outside a flywheel or a leading disk of the hydrotransformer). The code from four figures specifies in dimensional groups шатунных necks коленвала, the first figure concerns a neck of 1st cylinder, and the fourth – to a neck of 4th cylinder. The code from five figures concerns dimensional groups of radical necks коленвала (subsection 3.2.2.8.2 see).

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. Having pressed on loose leaves, lay the top and bottom loose leaves on the places. Be convinced that ledges on bearing loose leaves have come into samples in a rod (are specified by arrows) and in a rod cover.
3. At installation of loose leaves it is forbidden to touch a working surface of loose leaves with fingers. Be convinced that the lubricant aperture in top шатунном the loose leaf was precisely combined with an aperture in a rod. If backlash check is carried out with old loose leaves be convinced that these loose leaves are established on former places.
4. The backlash in шатунных bearings can be checked up in two ways. At backlash definition by the first way it is necessary to collect covers with rods and шатунными bearings, having tracked correctness of mutual orientation of these details. Tighten nuts шатунных covers with the set moment and measure internal diameter of each collected pair loose leaves with the help нутромера with стрелочным the indicator or кронциркуля. The backlash in radical bearings is defined as a difference of internal diameter collected шатунных bearings and diameter corresponding шатунных necks коленвала.
5. The second way (more exact) consists in application plastic калибровочной wire Plastigage of the round section laid on carefully cleared surfaces шатунных of necks.
6. Establish шатунные bearings, it is correct them сориентировав. On everyone шатунную a neck коленвала put on a piece калибровочной a wire.
7. 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.
8. Tighten nuts of covers (see more low). At a tightening change of position of a wire is not supposed, also it is not supposed проворачивание коленвала.
9. 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.
10. 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. 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. If the width of the flattened wire from one edge is more, it specifies on конусность шатунной necks.
11. If the backlash differs from norm at measurements with old loose leaves repeat measurements with new loose leaves. If and with new loose leaves the backlash exceeds norm it is necessary to address for consultation in service of car-care centre of the dealer, or to the expert in the given engine to receive council how to operate further. Probably that it is necessary перешлифовать шатунные necks коленвала and to replace loose leaves repair.
12. If necessary get loose leaves of corresponding dimensional group and repeat procedure of measurement of a backlash in шатунных bearings.
13. Upon termination of scratch out a nail or a wooden chip the rests калибровочной a wire from radical necks коленвала, without having damaged thus their surface.

Installation of shatunno-piston group

The further description is conducted in that assumption that assemblage will be carried out after is established коленвал in gathering with all radical bearings and with covers (with a skeleton of covers).

PERFORMANCE ORDER
1. Be convinced of correctness of installation шатунных bearings (subitem 4 and 5 see). If new bearings carefully remove the rests of preserving greasing are established, having washed out them in kerosene. Dry wipe rods and bearings a fabric not leaving pile.
2. Be convinced of correct arrangement of joints of piston rings and compress rings the special adaptation.
3. 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.
4. Assemblage begin with 1st cylinder. Be convinced of correct arrangement of joints of piston rings (subsection 3.2.2.12 see) and compress rings the special adaptation.
5. 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 cover of a chain drive of cam-shafts. 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.
6. Be convinced that шатунные loose leaves are established correctly and plentifully grease loose leaves and шатунную a neck коленвала. Cautiously, not to damage a cylinder surface, draw a rod to a neck коленвала. Dress 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).
7. Tighten nuts шатунных covers with the moment of 1st stage of an inhaling with the help динамометрического a key and a face head (a photo at the left). Then tighten nuts on a corner of 2nd stage of an inhaling, or in the absence of a key with an angular scale, tighten with the moment of 2nd stage (a photo on the right).
8. Turn коленвал and check up freedom of its rotation. If new details appreciable constant resistance to rotation коленвала should be felt are established, however коленвал should be turned smoothly, without jammings.
9. Similarly establish other pistons and rods.
10. Establish a head of cylinders, a chain (or chains) a drive of cam-shafts and the oil pallet.
