2.3. Top dead point of the first cylinder

GENERAL INFORMATION

Prevention

The sequence of operations is presented in the assumption that the distributor of ignition is installed correctly. If it is necessary to define the top dead point for installation of the distributor, install the piston of the first cylinder in the top dead point in a compression step, then expose ignition tags.


The top dead point of the piston is a point through which passes each piston at a provorachivaniye of a cranked shaft. Each piston reaches situation VMT at the end of a step of compression then again at the end of an exhaust step. For the purpose of installation of the mechanism of gas distribution of the engine the top dead point of the piston of the first cylinder is used.

Arrangement of the piston exactly in the top dead point extremely important when carrying out many works, for example, at removal of a camshaft, a gear belt and a pulley of a camshaft and the distributor of ignition.

Before works on installation of the piston of the first cylinder in the top dead point, be convinced that the lever of gear shifting is in neutral situation, and the emergency brake will be tightened. Disconnect system of ignition, having taken out a main line a ny wire from a cover of the distributor and having grounded it on weight. Unscrew spark plugs.

For installation of any of pistons in the top dead point rotate a cranked shaft one of the methods described below. Thus rotate a cranked shaft of the engine clockwise.

The most preferable method is a provorachivaniye of a cranked shaft of the engine for a bolt of fastening of a pulley of a cranked shaft.

For saving of time it is possible to use a starter for a piston supply to the top dead point. Exact installation of the piston is carried out by turn of a cranked shaft for a bolt of fastening of a pulley of a cranked shaft to the top dead point.

PERFORMANCE ORDER

1. Note position of the plug of the first cylinder on a distributor cover. If the tag is absent, determine it by the high-voltage wire going from a candle of the first cylinder.

2. Using chalk or a felt-tip pen, put the tag located under contact of the first cylinder on the distributor case.

3. Uncover the distributor and move it aside.
4. Turn a cranked shaft of the engine until the tag on a pulley of a cranked shaft is combined with figure 0 on a plate of the installation of the mechanism of gas distribution located on the forward party of the engine.
5. Check the provision of a rotor of the distributor which has to be directed on the tag applied on the distributor case.
If the rotor of the distributor is sent to the opposite side, the piston of the first cylinder is in the top dead point in an exhaust step.
For installation of the piston of the first cylinder in VMT in a step of compression turn a cranked shaft on 360 ° clockwise. Thus the rotor of the distributor has to be combined with a tag.
