GRM incentive - the general information, service of components

Waves of curves can proworatschiwatsja without risk of collision of gates with pistons in case the bent shaft is given to situation 45 ° in front of the WMT piston of the first cylinder.

The gas chain of the switch can be replaced without motor discussion. By means of mentioned below tools the new chain can be included too as before, is passed around starlets and satschekanena (watch office compensation of a chain of an incentive of GRM)

At wrong installation collision of gates can happen by means of lands of pistons!

General information

For execution of procedures of removal and the device of elements of an incentive of GRM will demand the following special tools:
  • Pencil of blocking of a wave of curves h4 - No. 111589031500;
  • Key of a wave of curves - No. 119589000100;
  • Tiskalshchik of plug / glass of a bent shaft - No. 103 589 003 300;
  • The tool for blocking of flywheel / priwodnogo Disk - No. 116 589 014 000;
  • The tool for the device of members of a gas chain of the switch - No. 000 589 584 300;
  • The offer of schtampoderschatelej for the device of members of a gas chain of the switch - No. 103 589 016 300;
  • Attenuators of a gas chain of the switch - No. 110589035900;
  • The tool for glass blocking - No. 603589004000.
    • If the next moments pay attention:
  • If it down especially, the motor does not remain only to proworatschiwajte in the normal direction;
  • Pay attention to the efforts of a delay of strengthening reserved by target figures;
  • At the corresponding complete set you do not forget to designate Einstellage of a sensor of CKP before removal;
  • Not proworatschiwajte a bent shaft for starlets of waves of curves, and also other starlets of an incentive of GRM;
  • Not proworatschiwajte of a wave of the handle and wave of curves at the accepted gas chain of the switch.

    • Service of components of an incentive of GRM

    Details of the device of elements of an incentive of GRM

    1 — Einstelzeichen for the management of the motor in position of WMT of the end of a step of compression of the first cylinder
    2 — kernels of diameter of 6.5 mm for fixing of waves of curves
    3 — During the chain device you pursue that superiority of the regulator of a wave of curves (3) were in situation "delay".
    4 — if blocking of a wave of curves from proworatschiwanija can be made by means of a key.
    5 — removal of installation of natjaschitelja of a chain


     EXECUTION ORDER

    1. Exclude the negative line of the battery.
    2. For the purpose of simplification of proworatschiwanija of the motor you pull out all spark plugs.
    3. Bring a bent shaft into situation 45 ° in front of the WMT piston of the first cylinder.
    4. Prodente in waves of curves blocking kernels (2) diameters of 6.5 mm.
    5. During the chain device you pursue that superiority of the regulator of a wave of curves of access (3) were in situation "delay".

    At wrong installation collision of gates can happen by means of lands of pistons!


    Before beginning execution of procedures of repair you accept installation of natjaschitelja, - you do not incline installation during removal.

    The final wave of curves of the right head of cylinders has to be blocked by a blocking kernel before removal of natjaschitelja.


     EXECUTION ORDER

    1. Blocking of a wave of curves from proworatschiwanija can be made by means of a key (4).
    2. Necessary repair of restoration fills, you establish natjaschitel into place.
    3. Tighten NEW bolts of the regulator access and starlets the termination of waves of curves with effort of 18 Nanometers (bolts of type I with the separated glass) or 20 Nanometers + 60 ° (bolts of type B with the established glass).

    During execution of works of repair it is necessary to replace it is necessary for bolts of type I with a unique bolt as watt

    4. On the motor 119.97 you replace a regulator feather if its volumes of requirements of specifications do not correspond.
    5. Tighten the NEW bolt of the regulator of a wave of curves of access with effort of 7 Nanometers (bolts of type I with the separated glass) or 5 Nanometers + 90 ° (bolts of type B with the established glass).


    During execution of works of repair it is necessary to replace it is necessary for bolts of type I with a unique bolt as watt


    On edition models to 07/94 you forget to grease in front of the device the central bolt of glass of a bent shaft and its glass () is not present.
