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

GENERAL INFORMATION

The top is dead a 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 a gazoraspredeleniye of the engine VMT of the piston of the first cylinder is used.

PERFORMANCE ORDER
1. Uncover heads of the block of cylinders.
2. Turn a cranked shaft of the engine a wrench for a bolt of fastening of a pulley of a cranked shaft before combination of adjusting labels with indexes.
3. The adjusting label of a pulley of a cranked shaft should be combined with the index on a cover of a driving chain.
4. The groove on a forward flange of a camshaft should be combined with a ledge on a forward cover of the bearing of a camshaft.
5. After combination of adjusting labels with indexes the piston of the first cylinder is in the top dead point.
