Replacement of a ring can be made in two ways. At removal the first way make the following:
– remove the transmission;
– remove a drive flywheel/plate;

– replacement of a sealing ring can be made, without removing the oil pallet and a back cover of the block of cylinders
. However it is not recommended to use this method as a working edge of a sealing ring very rigid and its damage to installation process is possible. An edge of the screw-driver take an old sealing ring from a nest. Clear a nest of a sealing ring and a neck of a bent shaft. Oil engine a working edge of a new sealing ring and a neck of a bent shaft and, pressing, establish a sealing ring. This work needs to be performed very carefully as it is easy to damage a working edge of a sealing ring.
The second — the main — the way of replacement of a sealing ring demands removal of the oil pallet and a back cover of the block of cylinders. For replacement of a ring by the second method make the following:
– remove the oil pallet. Turn out bolts and remove a back cover of the block of cylinders. A firm plastic or wooden scraper clear privalochny surfaces of a back cover and the block of cylinders of the remains of old laying;

– establish a back cover on two wooden whetstones, the hammer and the screw-driver beat out a sealing ring
– establish a new sealing ring in a back cover for what use flat wooden whetstone or a tubular mandrel, with outer diameter a little smaller the outer diameter of a ring;
– oil engine a working edge of a new sealing ring and a neck of a bent shaft. Install new laying on the block of cylinders;
– slowly and carefully establish a back cover with a sealing ring on a bent shaft, to its prileganiye to the block of cylinders. Fix a cover by bolts, having tightened their moment 13 N • m. Make sure that the lower plane of a cover does not support the privalochny surface of the block of cylinders on which the oil pallet is installed.
You carry out further installation to the sequences, the return to removal.
