5.8. Installation of the piston of the first cylinder in the provision of VMT of a step of compression

The piston of the 1st cylinder is installed in the top dead point (TDP) of a step of compression in order that at work, the chains of the drive of the gas-distributing mechanism connected with removal, installation of phases of gas distribution was not broken. At violation of phases of gas distribution the engine will normally not work.
Expose VMT on tags on a pulley of a bent shaft and a cover of a chain (at the same time in VMT there are pistons of the 1st and 4th cylinders), turning a bent shaft for a bolt of a pulley of auxiliary units.
After that be surely convinced that tags on gear wheels of camshafts are located horizontally at the level of the top plane of a head of the block and are sent to the opposite sides, for this purpose uncover a head of the block of cylinders. After installation of the piston of the 1st cylinder in VMT do not turn distributive, cranked and intermediate shaft.
If tags on gear wheels of a bent shaft do not coincide, so installation of phases of gas distribution is broken (the piston of the 1st cylinder is not installed in VMT). In this case it is necessary to expose VMT on tags on drives of the gas-distributing mechanism and to turn a bent shaft before combination of tags.
You will need a cap key "on 36".
1. A cap key turn a bent shaft for a bolt of a pulley of auxiliary units …
2. … before coincidence of tags on a cover of a chain and a pulley of the drive of auxiliary units.
3. Uncover a cylinder block head (see. "Replacement of laying of a cover of a head of the block of cylinders").
4. Check coincidence of tags on camshafts.
