5.5. Top Dead Point (TDP) of the piston of the first cylinder


Use of a drill with a diameter of 4 mm for check of correctness of installation of the camshaft

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 compression step, then again at the end of an exhaust step. For the purpose of installation of the mechanism of gas distribution of the engine VMT of the piston of the first cylinder is used.

Arrangement of adjusting tags on the engine at installation of the piston of the first cylinder in the top dead point
And – placement of curved cores (1) in adjusting openings;
In – the tag on a pulley of a bent shaft is combined with a side side of an arm, the sensor of an angle of rotation of a bent shaft

Removal of a hose of ventilation of a case from a cover of a head of the block of cylinders on models with system of injection of CIS fuel

PERFORMANCE ORDER
1. Note position of the plug of a high-voltage wire of the first cylinder on a distributor cover.
2. Uncover a head of the block of cylinders.
3. For a bolt of fastening of a pulley of a bent shaft turn a bent shaft of the engine clockwise, the following tags will not be combined with indexes yet (see rice. An arrangement of adjusting tags on the engine at installation of the piston of the first cylinder in the top dead point, Removal of a hose of ventilation of a case from a cover of a head of the block of cylinders on models with system of injection of CIS fuel):
a – the tag on a pulley of the camshaft has to be combined with a side side of an arm for the sensor of an angle of rotation of a bent shaft;
b – adjusting openings in forward flanges of camshafts have to settle down outside of and at the level of the top plane of a head of the block of cylinders;
c – the rotor of the distributor of ignition has to be combined with the plug of a high-voltage wire of the first cylinder.
4. After combination of all tags the piston of the first cylinder is in the top dead point in a compression step.
