| 1. Arrange the block so that the lower part was turned up.
| 2. Turn off bolts of covers of radical bearings, get covers and spread out them as their installation.
| 3. Get from covers and the block of cylinders inserts of radical bearings. Wipe surfaces of the lower and top inserts the pure fabric which is not leaving pile. These details should be preserved in full purity!
|Check of gaps in radical bearings
|4. Clear an external surface of the new radical inserts having oil flutes, and enclose them in beds of the block of cylinders. Enclose the corresponding reciprocal inserts in covers. Be convinced that the ledge on an insert coincides with selection on the block or on a cover. Besides, the opening of the oil channel in a bed of the block of cylinders has to be combined with a lubricant opening in an insert.
Are not allowed installation of an insert in a place by blows of a hammer, and also drawing scratches at installation. At this stage it is not required to grease an insert.
|5. Persistent half rings are established in a saddle and a bed of the central insert (number 3).
|6. Wipe working surfaces of inserts in the block and radical necks of a cranked shaft the pure rags which is not leaving pile. Check or clear oil channels of a cranked shaft as now the only way of an exit of any pollution lies via new bearings.
|7. At full confidence in purity of a shaft carefully put it in a place on inserts of radical bearings.
|8. Before final installation of the crankshaft it is necessary to check a gap in radical bearings.
|9. Prepare some pieces of a calibration plastic wire of "Plastigauge" which length is a little less than width of radical bearings, and put on one piece on each radical neck of the crankshaft parallel to its axis.
|10. Clear surfaces of inserts in covers and establish covers in a place (do not mix them) so that shooters were turned towards forward part of the engine. To touch a plastic wire it is not allowed. Slightly grease carvings and internal surfaces of heads of bolts, wrap bolts.
|11. Tighten in three steps till the moment specified in subsection 188.8.131.52. bolts of fastening of covers, tighten bolts in the specified sequence (see rice. Sequence of an inhaling of bolts of covers of radical bearings). At a tightening of bolts rotation of the crankshaft is not allowed.
|12. Turn off bolts of covers and carefully lift covers of radical bearings. Arrange covers as it should be corresponding to a place of their installation. To violate the provision of a calibration wire and to rotate a cranked shaft it is not allowed. If removal of a cover is complicated, displace a cover slightly having knocked sideways with a hammer with soft the brisk.
|13. Compare thickness of each of crushed calibration a provolok (by the widest part of a wire) with a scale on packing, determine gap size in radical bearings and compare to standard value. Do not mix a unit of measure, values of a scale are specified in inches and millimeters.
|14. If the gap does not meet standard, the wrong selection of dimensional group of inserts can be the cause (the order of selection is described in subsection 184.108.40.206. Before making the decision on replacement of inserts be convinced that at measurements there were no pollution or oil between bearings and the interfaced surfaces of covers and beds of the block of cylinders. If width of the crushed wire on the ends strongly differs, the radical neck of the crankshaft has conicity (see subsection 220.127.116.11).
|15. Carefully scratch out the remains of calibration material from necks of a cranked shaft and / or from surfaces of radical bearings. Do not allow damage of surfaces of radical bearings.
|Final installation of the crankshaft
|16. Carefully get a cranked shaft from the block of cylinders. Clean working surfaces of radical bearings and apply on each insert of the bearing a thin uniform layer of greasing on the basis of a disulfide of molybdenum or oil for assembly of the engine. Grease also surfaces of persistent half rings.
|17. Grease the crankshaft necks which are in contact with epiploons greasing on the basis of a molybdenum disulfide, oil for assembly of the engine or fresh oil for the engine.
|18. Be convinced of purity of necks of a cranked shaft, then install it in the block of cylinders. Clear surfaces of inserts in covers and apply a thin film of greasing on each of them. Establish covers on the former places so that shooters were turned towards forward part of the engine.
On each side the central bearing surely establish persistent half rings.
|19. The top persistent half rings (from the block of cylinders) can be established into place by turn round a crankshaft neck when the last is installed in the block of cylinders. Flutes of half rings have to be turned outside.
|20. The lower persistent half rings with adjusting ledges have to be put on covers of bearings by flutes outside so that ledges came into grooves on covers.
|21. Slightly grease carvings and internal surfaces of heads of bolts of covers, wrap bolts. Tighten bolts in three steps till the moment specified in subsection 18.104.22.168 tighten bolts in the specified sequence (see rice. Sequence of an inhaling of bolts of covers of radical bearings).
|22. Check freedom of rotation of the crankshaft, having turned by hand on some turns.
|23. The probe or the indicator check an axial side play of the crankshaft (see subsection 22.214.171.124). If surfaces of persistent half rings are not worn-out or are not damaged or if new persistent half rings are established, the axial side play has to meet standard.
24. Establish a new epiploon in the holder and fix the holder bolts on the block of cylinders (see subsection 126.96.36.199).
