Installation of a cranked shaft and check of working gaps of radical bearings

 PERFORMANCE ORDER

1. Installation of a cranked shaft is the first step actually engine assemblies. It is meant that at this stage the cranked shaft and the engine block already are properly cleaned, checked and restored.
2. Overturn the engine upside down.
3. Give fixing bolts and remove covers of radical bearings and/or assembly of their bridge.
4. If yet did not do it, take from the beds in the block and covers old loose leaves of radical bearings. Wipe beds pure неворсящейся rags – they should be irreproachably pure.

Check of working gaps of radical bearings

Try not to touch surfaces of new loose leaves barehanded in order to avoid undesirable contact of bearings to traces of oil always present on fingers and chemically aggressive substances.


 PERFORMANCE ORDER

1. Wipe backs of new loose leaves of radical bearings and enclose equipped with an oil flute (if that is provided) halves in the beds in the block. The remained halves of loose leaves enclose in the corresponding covers of bearings. Track, that uvulas of loose leaves entered into reciprocal landing grooves in beds of the block and covers. Oil openings in the block should appear also correctly are combined with openings in loose leaves.

By no means do attempts to begin to knock the loose leaf resistant to installation in the bed by a hammer. Grease with nothing bearings at this stage!


2. The persistent loose leaves (washers) equipped with flanges should be established in a bed of the fourth (considering from a belt of a drive of GRM) the radical bearing (see an accompanying illustration).

3. Wipe surfaces of bearings in the block and radical necks of a cranked shaft pure неворсящейся rags.
4. Check passableness of oil openings of a shaft, in case of need clean them. Any containing in маслотоках extraneous particles eventually inevitably get to bearings.
5. Carefully wiped cranked shaft accurately lay in radical bearings of the block.
6. Before establishing a shaft finally, it is necessary to check sizes working gaps in its radical bearings.

7. Cut the calibrated plastic wire from a measuring set of Plastigage pieces, in the length width of loose leaves are slightly shorter, and lay on one slice of a wire along each of radical necks of a shaft, parallel to their axis (see an accompanying illustration).

8. Wipe surfaces of loose leaves in covers and establish the last and/or assembly of their bridge on the regular place. Try not to shift laid along shaft necks pieces of the calibrated wire. Slightly oil a carving of fixing bolts and screw them, having fixed covers.

9a. In the order specified on an accompanying illustration in three stages tighten bolts of fastening of covers and/or their bridge with demanded effort (Civic).

9b. In the order specified on an accompanying illustration in three stages tighten bolts of fastening of covers and/or their bridge with demanded effort (Integra).


Do not allow a shaft provorachivaniye in the course of a fixture tightening!


10. Turn out bolts and carefully remove covers radical and/or assembly of their bridge. Combine the removed covers as an arrangement them on the engine. Try not to damage the flattened-out calibrated wire and do not turn a shaft. If any of covers does not give in to removal, it is accurate обстучите it for release by a hammer with soft the brisk.

11. On the width of the flattened-out threads measured on a scale, put on packing of a set of Plastigage, define size of working gaps of bearings (see an accompanying illustration). Compare results of measurements to requirements of Specifications.

12. If the size of a gap leaves out of admissible limits, loose leaves not that standard size (were probably established see. Check of a condition and selection of loose leaves of radical and shatunny bearings of a cranked shaft). Before looking for new loose leaves, make sure that under the enclosed dirt or oil did not get. If the calibrated wire is flattened out since one end more than from another, it testifies to existence of a konusnost of a neck (see. Check of a condition of a cranked shaft).
13. Carefully remove the calibrated wire from necks, having scratched out all its traces any not too strong tool (for example, edge of an old credit card). As a last resort, it is possible to use own nail, the main thing that on a surface of necks/loose leaves did not remain scratches and задиров.

Final installation of a cranked shaft

If the engine is equipped with the bridge of covers of radical bearings (В18С1, В18С5, D16Y5, to D16Y7 or D16Y8), at first establish into place shatunno-piston group (see. Installation of shatunno-piston assemblies and check of size of working gaps in shatunny bearings of a cranked shaft). Then bring all pistons into provisions VMT that they did not disturb camshaft installation.


 PERFORMANCE ORDER

1. Carefully take a cranked shaft from the engine.
2. Wipe surfaces of bearings in the block and evenly grease them with a thin layer of molibdensoderzhashchy assembly impellent greasing. Do not forget to grease persistent surfaces of the fourth bearing also.

Try not to allow greasing hits on backs of loose leaves!


3. Make sure of absoluteness of purity of necks of a cranked shaft, then grease (the same greasing) surfaces of pins contacting to epiploons and accurately lay a shaft in the block.
4. Wipe and grease surfaces of loose leaves in covers.
5. Establish on the engine of a cover of radical bearings and/or assembly of their bridge.
6. Screw fixing bolts.
7. In a demanded order, tighten bolts of fastening of covers of all bearings with demanded effort.
8. Several times turn a cranked shaft manually, checking freedom of its rotation.
9. In summary with the help щупа lezviyny type or a measuring instrument of DTI define size axial люфта in bulk (see. Removal of a cranked shaft). If persistent surfaces of a shaft are not worn-out and are not damaged, and bearings are replaced on new, axial люфт should not leave for admissible limits.
10. Establish a new back epiploon of a cranked shaft (see. Replacement of a back epiploon of a cranked shaft).
