- Remove panels of finishing of a cover of a head of cylinders.
- Remove nozzles (Y76).
- Uncover a head of cylinders (12).
- Turning a bent shaft in the normal direction, bring the engine into the provision of VMT of the piston of the first cylinder, - tags on bodies of camshafts and covers of bearings have to be combined (shooters).
- Block the inlet camshaft (2), having passed a special core (3) through a cover of the bearing and having entered it into an opening (A) of a driving gear wheel (5).
- Remove a natyazhitel of a chain (10) (see the Section Removal and installation of components of the GRM drive).
- Remove a forward cover of a head of cylinders (see the Section Removal and installation of covers of the GRM drive).
- Remove the top guide of a chain (see the Section Removal and installation of components of the GRM drive).
- Mark the provision of a chain on an asterisk of the drive of camshafts (6).
- Otboltite an asterisk (6) also remove it from a pin of the final camshaft (1).
- Previously having marked, uncover bearings of camshafts (8).
- Carefully take camshafts (1 and 2) from a head of cylinders.

- Details of installation of face covers of camshafts are shown on an illustration to which all references which are found in the text belong.
- Remove camshafts (1 and 2) (see above).
- Having hooked the suitable screw-driver, take a cover (3) from a face part of a back pin of the camshaft, - try not to damage walls of a landing nest.
- Clean and degrease a nest under installation of a cover.
- By means of a suitable mandrel put in a shaft pin a new face cover on the required depth.

- Disconnect the air distributor.
- Disconnect an inlet sleeve of a path of pressurization of air from a head of cylinders and a turbocompressor and wring out it aside.
- Uncover nozzles.
- Remove nozzles (Y76).
- Uncover (2) corresponding heads of cylinders.
- Remove bypass a sleeve of a path of pressurization of air.
- Remove the vacuum pump (4).
- Having turned a bent shaft in the normal direction, bring the engine into the provision of VMT of the piston of the first cylinder, - tags on bodies of camshafts and their covers have to be combined.
- Block the inlet camshaft (6), having passed a core (7) through a cover of the first bearing and having filled it in an opening (A) in a driving gear wheel (8).
- During the work on the right head, working through a window in a forward cover, put the holder on an asterisk of the drive of camshafts (10). On the left head the special holder fastens on a head of cylinders, is put on a driving asterisk (10) and fixed by bolts (14) of a cover of a head of cylinders.
- Separate a driving asterisk (10) from a pin of the final camshaft (12).
- Uncover (13) bearings of camshafts (6 and 12) and take the last of a head of cylinders, - an asterisk leave recorded in the holder.

Alternatively pushers can be taken from a bed of shaft, however it is not necessary to use a magnet for this purpose, - magnetization of pushers is fraught with accumulation on them metal sawdust! |
- Take a bed of camshafts (10).
- Installation is made upside-down.
- Start the engine and check it for existence of signs of development of leaks.
- In conclusion make cleaning of memory of the module of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).
