Fixing cranked/distributive shaft and TNVD for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car

Do not undertake attempts of a provorachivaniye of the engine at blocked cranked/distributive shaft/TNVD. If the engine is left blocked for a long time, it is necessary to establish warning plates of the corresponding contents in salon and an impellent compartment of the car. Such precautionary measure will allow to avoid a casual provorachivaniye of the blocked engine a starter that is fraught with serious mechanical damages.


 PERFORMANCE ORDER

1. On all models in camshaft and TNVD cogwheels, and also in a flywheel the special drillings, allowing to make engine fixing in the correct phase of a gazoraspredeleniye excluding probability of hit of valves in contact to the bottoms of pistons in an installation time of a head of cylinders/belt of a drive of GRM are provided. Having achieved combination of these drillings with reciprocal openings in the head/block of cylinders, it is necessary to pass in them fingers of suitable diameter.

At combination of blocking openings the piston of the fourth cylinder appears in the provision VMT of the end of a step of compression. The detailed description of procedure of blocking of the engine below is provided.

2. Remove the top covers of a belt of a drive of GRM (see. Removal and installation of covers of a gas-distributing belt).
3. Turn a cranked shaft for a bolt of its pulley so that three drillings in camshaft and TNVD cogwheels (one in a wheel of a shaft and two in a pump wheel) were combined with reciprocal openings to a forward plate of the engine. For ensuring access to a bolt of a pulley of a cranked shaft release two clamps and remove a plastic cover from a podzor of the right forward wheel of the car. Where it is required, liberate also hoses of an okhladitelny path from clips on an arm. Remember that the cranked shaft should be turned always only in the direction clockwise, looking from the right board of the car. When openings will appear are combined, the engine is blocked by a prodevaniye in them metal cores of the corresponding diameter (see below).

4. Pass 8-millimetric a core/drill through an opening in the left flange of the block near a starter.

5. In case of need slightly correct the provision of a cranked shaft, achieving demanded combination of openings and free introduction of a core in flywheel drilling / a driving disk.

6. Pass three 8-millimetric bolts in drillings in camshaft and TNVD cogwheels and manually screw them in reciprocal openings in the engine.



7. Now both shaft and TNVD will appear blocked in safe provisions.
