3.1.2.9.3. Installation and check of backlashes in radical bearings


Selection of loose leaves of new radical bearings
The prevention

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


New radical bearings steal up according to the codes of identification put on коленвал and on the block of cylinders.

On коленвале codes are put on a cheek of a neck of 1st cylinder (from outside chain covers). The code from five figures concerns diameters of radical bearings, – the first figure means a code for 1st radical neck коленвала, and the fifth – a code for 5th neck.

The prevention

In some engines on a cheek коленвала codes from four figures which specify in dimensional group шатунных bearings (see subsection 3.2.2.10.2) also are put.


On the block of cylinders dimensional codes are beaten out in the basis from outside a flywheel.

To pick up loose leaves of radical bearings it is necessary to learn dimensional group for расточки under the loose leaf which has been beaten out on the block of cylinders, and a code of dimensional group of a corresponding radical neck which is put on коленвале, 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 its lateral surface.

Check of backlashes in radical bearings

PERFORMANCE ORDER
1. Clear an external surface of new radical loose leaves, surfaces расточек under loose leaves in the block of cylinders and in covers of radical bearings.
2. Establish the top loose leaves, having combined ledges with deepenings in the block of cylinders (marksman).
3. Establish in covers the bottom loose leaves, also having combined a ledge with deepening (it is specified by an arrow).
4. It is forbidden to touch a working surface of loose leaves with fingers. Keep in mind that on all top radical loose leaves the lubricant flute and an aperture for an oil supply are provided. The bottom loose leaves continuous. If the backlash is checked on old loose leaves track that they have been established on former places.
5. The backlash can be checked up in two ways.
6. At backlash definition by the first way establish covers (or a skeleton of covers) radical bearings together with loose leaves on the block of cylinders, tighten bolts with the set moment and measure internal diameter of each collected pair loose leaves. The backlash in radical bearings is defined as a difference of this diameter and diameter of radical necks коленвала.
7. The second way (more exact) consists in application plastic калибровочной a wire.
8. Having established into place radical loose leaves, cautiously put коленвал. Radical necks should be dry and pure.
9. Prepare some pieces калибровочной the plastic wire Plastigage which length is a bit less than width of radical bearings, and put on one piece on each radical neck коленвала in parallel its axis.
10. Establish on covers with the bottom loose leaves, without breaking their orientation.
11. Tighten bolts with the set moment, in the specified sequence. Tighten bolts with identical, constantly increasing effort. During an inhaling position of a piece of a wire should not to change, turn коленвала is not supposed.
12. In sequence of return specified turn away bolts of covers, turning on on one turn for reception.
13. Remove covers (or a skeleton), without having broken position flattened проволок and without supposing turn коленвала.
14. Compare width crushed проволок to a scale on packing and define a backlash in the radical bearing. Compare to standard value.
15. If the backlash differs from standard wrong selection of loose leaves (or their raised deterioration if loose leaves were in operation were checked can be the reason).
16. Before coming to a conclusion about necessity of replacement of loose leaves be convinced that between covers or the block of cylinders and the loose leaf at measurement there was no dirt or oil.
17. If the width of the flattened wire from one edge is more, it specifies on конусность necks.
18. If the backlash differs from norm at measurements with old loose leaves repeat measurements with new loose leaves.
19. If and with new loose leaves the backlash exceeds norm it is necessary to address for consultation in car-care centre service. It can be necessary перешлифовать necks коленвала and replace loose leaves repair.
20. If necessary get loose leaves of corresponding dimensional group and repeat procedure of measurement of a backlash in radical bearings.
21. Upon termination of scratch out the rests калибровочной a wire from radical necks коленвала, without having damaged thus a surface.

Definitive installation коленвала

PERFORMANCE ORDER
1. Cautiously get коленвал from the block of cylinders.
2. Establish loose leaves of radical bearings on places.
3. If new loose leaves carefully wash out them in kerosene are established.
4. Wipe dry loose leaves and rods.
5. Plentifully grease with fresh oil for the engine of a surface of the loose leaves established in the block of cylinders.
6. Grease with a thin layer консистентной greasings persistent half rings and attach them on both parties of 3rd radical bearing.
7. Pay attention to that lubricant flutes on both half rings have been turned aside from the block of cylinders.
8. Establish коленвал in the block of cylinders and check up axial люфт.
9. Carefully clear of greasing demountable planes of covers of radical bearings and the block of cylinders.
10. Grease with fresh oil for the engine of a surface of the bottom loose leaves. Be convinced that adjusting ledges on loose leaves come into deepenings in covers.
11. Establish covers on former places, being guided on the put labels.
12. Tighten bolts by hand.
13. Tighten bolts of covers in the specified sequence approximately to half of set moment. Then, having repeated procedure, tighten bolts till the set moment.
14. Check up rotation freedom коленвала.
15. Establish rods with pistons.
16. Put a label specifying depth of landing of an epiploon in the holder and get an epiploon, having hooked its screw-driver.
17. Запрессуйте a new epiploon easy blows of a hammer, on depth which corresponds to the put label.
18. Put on a demountable surface of the holder of an epiploon a strip of hermetic and establish on the block of cylinders.
19. Tighten bolts with the set moment.
20. Establish a flywheel, chains of a drive of cam-shafts and the oil pallet.
