3.3.4. 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.

Removal

PERFORMANCE ORDER
1. Remove a negative wire from the accumulator. Lift a forward part of the car and fix on supports. Remove the right forward wheel.
2. Remove the top casing of a gear belt.
3. Turn the engine a wrench for a pulley of a cranked shaft clockwise. Rotate a cranked shaft until the label on a pulley of a cranked shaft will not be combined with the index on the basis of the oil pump.
4. To define that the first or fourth piston is in the top dead point, check the provision of adjusting openings in pulleys of the fuel pump and a camshaft. When the piston of the first cylinder is in the top dead point in the compression step, both openings of a pulley will be combined with openings under the screw in a head of the block of cylinders.
5. At installation of the piston of the first cylinder in VMT if it is necessary, it is possible to fix pulleys of the fuel pump or a camshaft for what screw in bolt М6 (a photo at the left) through a camshaft pulley in a head of the block of cylinders and bolt М8 (a photo on the right) through a pulley of the fuel pump in the block of cylinders.
