2.2.25. Installation of a back epiploon of a cranked shaft

 PERFORMANCE ORDER

  1. At first it is necessary to establish a cranked shaft, then to tighten bolts of covers of radical bearings. Then in the holder establish a new epiploon and tighten bolts of fastening of the holder to the block.
  2. Before installation of a cranked shaft very carefully check a surface of contact to an epiploon about scratches and jags which can damage a fillet of a new epiploon and cause leakages of oil. If the cranked shaft is damaged, the unique alternative is other or new cranked shaft if in a mechanical workshop will not offer a way of repair.
  1. The old epiploon can be taken from the case by means of a hammer and a punch, influencing from the back party. Do not forget to pay attention before extraction, on what depth the epiploon is established in the case; the new epiploon should be established on the same depth. Be very careful not to scratch or put other damages to an opening in the case, differently there can be a leakage of oil.
  1. Be convinced that the holder pure, then put on the external region of a new epiploon a thin layer of impellent oil. The epiploon follows plainly задавливать in a case opening therefore application of a hammer is undesirable. If the press is inaccessible, clamp the case and an epiploon between two smooth whetstones of a tree and press an epiploon into place between sponges of a big vice. Whetstones of a tree should be rather thick that the effort was distributed evenly on all circle of an epiploon. Working slowly, being convinced that the epiploon plainly enters into a case opening.
  1. Before putting on the epiploon/holder a cranked shaft and to tighten bolts, it is necessary to grease fillets of an epiploon with universal greasing or pure impellent oil. Establish new laying - hermetic is not required, and before installation of the holder be convinced that directing pins are on the places.
  1. Gradually tighten nuts/screws of the holder while they will not be hardly wrapped up, tighten them with the effort specified in the Size table and adjusting data at the end of the Management.
