Ring replacement can be made in two ways. At removal by the first way make the following:
– Remove a transmission;
– Remove a drive flywheel/plate;

– Replacement of a sealing ring can be spent, without removing the oil pallet and a back cover of the block of cylinders (fig. 3.46
). 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. A screw-driver edge take an old sealing ring from a nest. Clear a nest of a sealing ring and a neck of a cranked shaft. Grease with engine oil a working edge of a new sealing ring and a neck of a cranked shaft and, pressing, establish a sealing ring. This work is necessary for carrying out very carefully as it is easy to damage a working edge of a sealing ring.
The second — the basic — the way of replacement of a sealing ring demands removal of the oil pallet and a back cover of the block of cylinders. For ring replacement on 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 of the rests of an old lining привалочные surfaces of a back cover and the block of cylinders;

– Establish a back cover on two wooden бруска
, a hammer and a screw-driver beat out a sealing ring (fig. 3.47
– Establish in a back cover a new sealing ring for what use flat wooden брусок or tubular the mandrel, with external diameter a bit smaller external diameter of a ring;
– Grease with engine oil a working edge of a new sealing ring and a neck of a cranked shaft. Establish a new lining on the block of cylinders;
– Slowly and cautiously establish a back cover with a sealing ring on a cranked shaft, to прилегания it to the block of cylinders. Fix a cover bolts, having tightened their moment 13 Nm. Be convinced that the bottom plane of a cover does not support привалочную a surface of the block of cylinders on which the oil pallet is established.
The further installation spend to sequences, return to removal.
