  2. Remove a forward cover of a head of cylinders (see. Section Removal and installation of covers of a drive of GRM).
  3. Having turned a cranked shaft in the normal direction, bring the piston of the first cylinder into situation 30 ° after VMT, - in this position of the engine camshafts can be turned without risk of collision of valves with pistons.
  4. Make sure of correctness of base installation of shaft (see. The section Installation of base provision of camshafts), then with a marker mark the provision of a gas-distributing chain (73) concerning asterisks (75 and 76) camshafts.
  5. Remove a natyazhitel of a chain (14) (see. Section Removal and installation of components of a drive of GRM).
  6. Remove an asterisk (76) final camshafts.
  7. Lift a chain (73) and remove an asterisk (75) inlet camshafts.
  8. By means of a rozhkovy key (1) develop camshafts (77 and 78) so that as much as possible to weaken effort developed by klapanny springs, - cams should be developed by heels to pushers.
  9. Mark covers of bearings of camshafts, then turn out fixing bolts and remove covers.
  10. Carefully take camshafts from a head of cylinders.
  11. Installation is made upside-down, - track correctness of an arrangement of bearing covers.
