The top dead point of the piston is a point through which there passes each piston at a provorachivaniye of a bent shaft. Each piston reaches the provision of 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.
The piston arrangement precisely in the top dead point is extremely important when carrying out many works, for example, at removal of the camshaft, a gear belt and a pulley of the camshaft and 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 is tightened. Disconnect system of ignition, having taken out the central 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 bent shaft one of the methods described below. At the same time rotate a bent shaft of the engine clockwise.
The most preferable method is a provorachivaniye of a bent shaft of the engine for a bolt of fastening of a pulley of a bent 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 bent shaft for a bolt of fastening of a pulley of a bent shaft to the top dead point.
