3.2.2.8.2. 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.


Codes of dimensional group radical and шатунных bearings

1. Radical bearings

2. Shatunnye bearings

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 the 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.


Codes of dimensional groups расточек under radical loose leaves

On engines codes of dimensional groups расточек under radical loose leaves are beaten out in the basis of the block of cylinders (are specified by an arrow).

On the block of cylinders dimensional codes are beaten out in the basis from outside a flywheel. On engines there is only a code from five figures, the first figure in this code concerns 1st radical neck коленвала, and the fifth – to 5th neck.

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. Having pressed on the loose leaf, lay it on the place. Be convinced that the ledge (it is specified by an arrow) on the bearing loose leaf has come into sample in расточке the block of cylinders or in a skeleton of covers of radical loose leaves. It is forbidden to touch a working surface of loose leaves with fingers.
3. Keep in mind that on all top loose leaves of radical bearings the lubricant flute and an aperture for an oil supply are provided. The bottom loose leaves continuous.
4. Establish in covers the bottom loose leaves (the flute and an aperture on these loose leaves are absent), also having combined a ledge with deepening.
5. If the backlash is checked on the loose leaves which were in operation track that loose leaves have been established on former places. The backlash can be checked up in two ways.
6. At backlash definition by the first way it is necessary to establish covers (or a skeleton of covers) radical bearings together with loose leaves on the block of cylinders (special measuring devices will be necessary for measurements by this way – нутромер with стрелочным the indicator, or a telescopic micrometer, and a usual micrometer). Tighten bolts of covers (skeleton) 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 internal diameter of the collected radical bearings and the measured diameter of radical necks коленвала.
7. The second way (more exact) consists in application plastic калибровочной wire Plastigage of round section (it is invented and is issued in the USA). The wire is flattened between the bearing and a neck коленвала. After removal of a cover of the bearing the wire remains in the flattened kind. Having compared width of the crushed wire with a scale applied on the complete set, it is possible to define a backlash in the bearing. The kalibrovochnuju wire can be got in service of car-care centre of the dealer. If the wire at the dealer does not appear, it can be got, having enquired at the agents specialising on delivery of spare parts for engines, and having received data on presence of this product in your region. Check of a backlash by means of calibre is carried out as follows.
8. Having established into place radical loose leaves, cautiously put коленвал. Any greasing on necks коленвала it is not supposed. 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 in a place of a cover with the bottom loose leaves. At installation of covers be guided on labels available on them to establish covers in former position.
11. Establish a cast skeleton of covers of radical bearings, wrap bolts and tighten them. During an inhaling position of a piece of a wire should not to change, turn коленвала is not supposed.
12. On all engines turn away bolts of fastening of covers. Turn on bolts in return sequence on one turn for reception. Turn out and get bolts from get them from the block of cylinders.
13. Remove covers of radical bearings (or a skeleton of covers), again watching that position flattened калибровочных проволок has not exchanged and it was not turned коленвал.
14. Compare width crushed проволок to a scale on packing and define a backlash in the radical bearing. Compare to a standard backlash.
15. Measurement of a backlash by comparison of width crushed калибровочной a wire with a scale on packing
16. 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). 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. If the width of the flattened wire from one edge is more, it specifies on конусность necks.
17. 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 also that it is necessary перешлифовать necks коленвала and to replace loose leaves repair.
18. If necessary get loose leaves of corresponding dimensional group and repeat procedure of measurement of a backlash in radical bearings.
19. Upon termination of scratch out a nail or a wooden chip the rests калибровочной a wire from radical necks коленвала, without having damaged thus a surface.

Definitive installation коленвала

PERFORMANCE ORDER
1. Cautiously get a cranked shaft from the block of cylinders.
2. Establish loose leaves of radical bearings on places, being guided by subitem 5 and 6. If new loose leaves carefully wash out them in kerosene are established, having removed the preservative rests. A fabric not leaving pile wipe dry loose leaves and rods. Plentifully grease with fresh oil for the engine of a surface of the loose leaves established in the block of cylinders.
3. Grease with a thin layer консистентной greasings persistent half rings and attach them on both parties of 3rd radical bearing. Pay attention to that lubricant flutes on both half rings have been turned aside from the block of cylinders.
4. Establish коленвал in the block of cylinders and check up axial люфт (subsection 3.2.2.8.1 see).
5. Carefully clear of greasing demountable planes of covers of radical bearings and the block of cylinders.
6. 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.
7. Establish loose leaves of radical bearings on former places, being guided on labels.
8. Establish a cast skeleton of covers of radical bearings, wrap bolts and tighten them while only by hand.
9. Tighten bolts of covers in sequence specified on drawing with the set moment of 1st stage.
10. A Dinamometrichesky key with a face head tighten bolts of covers with the set moment of 1st stage.
11. Tighten bolts on a corner corresponding to 2 stage of an inhaling, observing the specified sequence. If there is no key with an angular scale tighten bolts динамометрическим a key with the moment specified for 2nd stage of an inhaling.
12. Check up rotation freedom коленвала then establish other details (see subitem 13-16).
13. Check up cleanliness of demountable surfaces of the holder of a back epiploon and the block of cylinders. Put a label specifying depth of landing of an epiploon in the holder, then get an epiploon from the holder, having hooked its big screw-driver with a flat edge.
14. Establish in the holder a new epiploon, having convinced that sponges of working edges are turned towards the engine. Запрессуйте an epiploon easy blows of a hammer, on depth which corresponds to the label put before removal of the fulfilled epiploon.
15. Check up available directing pins, then put on a demountable surface of the holder of an epiploon a hermetic strip. Dress the holder of an epiploon on коленвал and establish on the block of cylinders. Tighten bolts of fastening with the set moment.
16. Establish a flywheel, chains of a drive of cam-shafts and the oil pallet.
