The engine should be hung out from above on the winch or a beam.

2. On models remove coupling assembly from RKPP (see the Head Stsepleniye and power shafts). At once check a condition of components of coupling and the directing bearing. On models with AT it will be a high time to check a state and to replace a forward epiploon / a sealing ring of the pump.
3. Mark with a marker or paint the provision of a flywheel / a driving disk concerning an end face of a bent shaft.
4. Turn out bolts of fastening of a flywheel / a driving disk to a bent shaft. If in the course of weakening of bolts the shaft begins to be turned, jam the screw-driver or mount between teeths of a wreath of a flywheel (RKPP), or pass a long drift throughout one of openings of a driving disk, having rested it against a ledge on the block (AT).
