2.1.15. Replacement of a back epiploon of a cranked shaft

 PERFORMANCE ORDER

  1. Remove a flywheel or a driving disk (see. Section Removal and flywheel installation / driving disk).
  1. Give bolts and/or nuts of fastening of the holder of an epiploon to the block of cylinders. Do not forget to give two bolts (in the bottom of) fastening of a back part of the pallet of a case to the lower part of the holder of an epiploon.
  1. Carry out a thin sharp knife between laying of the pallet of a case and a forward cover, separating thus laying from a cover. Be very careful not to damage and to soil laying that you could use it again then.
  2. Destroy laying hermetic between the holder and the block of cylinders, обстучав a cover a hammer with rubber brisk or a usual hammer, having put wooden whetstone. Do not push anything between a cover and the block not to damage a laying surface.
  3. Using a scraper, remove all traces of a material of old laying from interfaced surfaces of the holder and the block of cylinders. On sale are available, and there can be useful, special solvents for removal of laying. After complete removal of a material of laying of a surface of laying it is possible to degrease, having wiped them a rag moistened in suitable solvent.

Be extremely careful not to damage and to scratch soft aluminum surfaces. Besides, try not to damage and not to soil laying of the pallet of a case.


  1. Prop up the holder two wooden whetstones and beat out an epiploon from the back party by means of a hammer and a screw-driver.
  1. Be careful, trying not to damage in the course of work an opening for an epiploon.
  1. Cover external diameter and sponges of a new epiploon with universal greasing and establish an epiploon in the holder by means of a hammer and wooden whetstone.
  1. Apply a thin film RTV type hermetic on a surface of laying of the pallet of the case, interfaced to the holder of an epiploon. Put more hermetic on regions where laying adjoins to the block of cylinders.

If laying of the pallet of a case is damaged, instead of complete replacement of laying you can try to cut off its forward part where it adjoins to the block of cylinders, then to cut off a forward part of new laying that it was just the same size. Cover an internal surface of the pallet a piece of rags, then clean off all traces of a material of old laying from interfaced surfaces. Attach a piece of new laying to the pallet by means of special gluing substance, then put RTV hermetic as it is described at the beginning of this paragraph.

  1. Grease both parties of new laying with RTV hermetic, then connect laying to the holder of an epiploon. Establish the holder on a back part of the engine, then get bolts and tighten them with demanded effort. Tighten bolts one by one according to the crosswise scheme to make it evenly.

At first tighten bolts of fastening of the holder to the block of cylinders, then bolts of fastening of the pallet of a case to a cover. If laying acts over connection of a cover with the block or forms folds in connection of a cover with the pallet, cut it that it stood correctly.


After RTV hermetic drawing assembly should be finished within 10 minutes to be in time before hermetic hardening.
