  4. Turn the engine in the normal direction (shooter) so that the inlet camshaft (1) could be blocked a core (4), - fill a core.
  5. If the pulley (2) belts of a drive of auxiliary units at the blocked shaft (1) appears displaced more than on 11 ° after VMT of rather adjusting label (3) (see the scale put on a pulley), it is necessary to replace a gas-distributing chain.
  6. Installation is made upside-down.
