The sequence of operations is made proceeding from the assumption that the distributor of ignition is established correctly. If it is necessary to define the top dead point for distributor installation, establish the piston of the first cylinder in the top dead point in a compression step, then expose ignition labels.
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 a gazoraspredeleniye 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 all-important at carrying out many works, for example, at removal of a camshaft, a gear belt and a pulley of a camshaft and the ignition distributor.
Before the beginning of 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 hand brake will tighten. Disconnect ignition system, having taken out the central wire from a cover of the distributor and having earthed 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 economy 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 to the top dead point by turn of a cranked shaft for a bolt of fastening of a pulley of a cranked shaft.
