3.1.2.5.5. A cranked shaft

THE GENERAL DATA

Designation of covers of radical bearings of a cranked shaft and covers шатунных bearings


Covers of radical bearings of a cranked shaft are numbered and turned by ledges towards a camshaft drive. Rods and their covers are designated by a special electric pencil.

Knot of the block of cylinders

1 – the block of cylinders, 2 – a sleeve of the cylinder, 3 – a sealing ring, 4 – the oil pallet, 5 – a cover of the forward radical bearing,

6 – a forward sealing ring, 7 – a cover of the radical bearing, 8 – a lining of a cover of the back radical bearing, 9 – a drain stopper of a cooling liquid, 10 – plugs

PERFORMANCE ORDER

1. To establish in the block of cylinders a cranked shaft (having established at first the loose leaves oiled). 2. To establish the oiled covers of bearings of a cranked shaft, observing designations (covers are numbered). It is necessary to direct ledges towards a camshaft drive (the ledge is specified by an arrow). The prevention №2 it is necessary to insert 4 persistent half rings of a cranked shaft into an installation time of a cover of the bearing a surface of sliding towards a cranked shaft (fig. Installation of persistent half rings of a cranked shaft see). 3. To clear surfaces of connection of the block of cylinders and a cover of the bearing №1, eliminating all traces of greasing. 4. To put on the block of cylinders in the top part of flutes of the bearing №1 small amount герметизирующего means Loctite Frenetanch. 5. To establish a bearing cover on the adjusted adaptation 0153. А1. A bolt to attach a cover to скобе adaptations (fig. Installation of a cover of the radical bearing №1 with the established lining see). 6. To grease and fix a cover of the bearing so that not to extend lateral linings:       – Inclined on 45 ° knot the adaptation-cover to establish in its nest;       – To straighten knot;       – Slowly to lower;       – To fix a cover one bolt;       – To take the adaptation in a vertical plane. 7. To level end faces of a lining concerning a surface of the block of cylinders; after installation they should act from the bearing on height 2 ±1 mm. 8. To check up axial backlash a cranked shaft and, in case of need, to replace persistent half rings of a cranked shaft on corresponding to it backlashу half rings (fig. Check axial backlashа a cranked shaft see). 9. By means of the adaptation 0153. With to establish a sealing ring from outside a flywheel (fig. Installation of a sealing ring of a cranked shaft from outside a flywheel – the adaptation 7.0153 see). 10. To check up выступание sleeves of cylinders (it выступание grows out of a parity of the sizes of the block of cylinders and a sleeve). 11. To insert four sleeves without linings. 12. To insert a plate 8.0132 In (the surface without an edge should be directed upwards) and to establish the indicator of hour type on an arm 8.0132 With. 13. To measure in three points выступание sleeves concerning the block of cylinders (0,08–0,15 mm). 14. To check up a difference between the measured values for points of measurement and for separate sleeves (0,05 mm are maximum). The prevention If sleeves new size change выступания sleeves and differences выступания by turn on 180 ° or installation site change in the block of cylinders is possible. 15. To designate (from outside the index of level of oil) sleeves of cylinders from 1 to 4 (1 from outside a flywheel).
