3.4.4. Top dead point (VMT) of the piston of the first cylinder

GENERAL INFORMATION

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 compression step, and then again at the end of an exhaust step. For the purpose of installation of the mechanism of a gozoraspredeleniye of the engine VMT of the piston of the first cylinder in a compression step is used. The N1 cylinder is from a gear belt. The cranked shaft of the engine rotates clockwise if to look on the right side of the car.

PERFORMANCE ORDER

1. Remove a weight wire from the accumulator. For improvement of access to a pulley of a cranked shaft tighten the hand brake, lift a forward part of the car and fix on supports.
2. To check an arrangement of cams of a camshaft, uncover heads of the block of cylinders or remove the vacuum pump of brakes, thus an opening for installation of the mechanism of a gazoraspredeleniye it will be visible on distributive to a shaft.
3. Turn the engine a wrench for a pulley of a cranked shaft before combination of an adjusting label on a pulley of a cranked shaft with the index. Thus pistons of the first and fourth cylinders become in the top dead points.

4. To define, what piston is in a compression step, check the provision of cams of a camshaft. If the piston of the first cylinder is in a compression step, cams of the first cylinder of a camshaft (are specified by shooters a photo at the left) will be directed up and the opening of installation of the mechanism of a gazoraspredeleniye (it is specified by an arrow a photo on the right) on the left side of a camshaft will be in the top situation. If cams of the first cylinder of a camshaft are directed down, turn a cranked shaft of the engine on 360 °.
	5. Remove the sensor of provision of a cranked shaft from the block of cylinders of the engine.
	6. For fixing of a cranked shaft in situation when the piston of the first cylinder is in the top dead point in a compression step, establish a pin through an opening of the sensor of a cranked shaft on a forward part of the block of cylinders.
