3.1.1.2. Installation of the piston of the 1st cylinder in MWT of a step of compression

GENERAL INFORMATION

Prevention

At the description of an order of performance of procedure it is meant that the distributor of ignition is correctly established in advance. In attempt to find VMT for the purpose of the correct installation of the distributor, it is necessary to check compression existence at the end of a piston stroke of the 1st cylinder through an opening for a candle then to combine labels of the moment of ignition, being guided by item 8.


The top dead point (VMT) is the highest point which the piston reaches, making back and forth motion in the cylinder. Each piston reaches VMT – at the end of a step of compression and at production of exhaust gases twice, however VMT is meant as VMT of a step of compression more often.

Piston installation (or pistons) in VMT of a step of compression is an integral part of many procedures, for example, removals of a gear belt and a conducted gear wheel or removal of the distributor of ignition.

PERFORMANCE ORDER
1. Before performance of procedure be convinced that the selector of transmission is established in the situation "Neutral", put the car on the hand brake, or block back wheels. Besides, completely exclude ignition operation for what disconnect a high-voltage wire of the coil of ignition from the central conclusion of a cover of the distributor and connect to weight on the block of cylinders by means of a crossing point. Turn out candles (see subsection 2.8.2).
2. For installation of any piston in VMT it is necessary to turn the crankshaft one of specified below ways. The normal direction of rotation of the engine - clockwise if to take a detached view of the engine of a gear belt.
3. It is preferable to rotate the crankshaft the face head dressed on a forward bolt of the crankshaft, by means of the extension piece – graggerses. Effort to apply only in the direction clockwise. It is forbidden to rotate a bolt counter-clockwise.
4. Ask the assistant to switch on and off quickly a starter and by that to establish the piston in the situation close to VMT (thus it is not necessary to use the remote switch). Final доворот the piston in VMT of a step of compression comes to the end, according to the previous point, a face head with a graggers. Previously ask the assistant to leave the car.
5. Find on a distributor cover the provision of a high-voltage wire of a candle of the 1st cylinder. If this conclusion is not numbered, determine it by a wire from a spark plug.
6. With a piece of chalk or a marker put labels on the distributor case, directly under a conclusion of the 1st cylinder.
7. Uncover the distributor (if necessary see subsection 2.8.3) and put aside.

8. Turn the crankshaft before label combination a pulley with figure "0" on a scale of installation of the moment of the ignition, cast in a forward part of the block of cylinders.
9. Check position of the distributor – the begunok should indicate a label put on the case of the distributor. If orientation a begunka corresponds described, the piston of the 1st cylinder is in VMT of a step of compression.
10. The bottom bolts of fastening of a case of coupling to the block of cylinders.
11. If the begunok specifies to the opposite side (situation differs on 180 °), the 1st cylinder is in release VMT.
12. To establish the piston of the 1st cylinder is in VMT of a step of compression, turn the crankshaft on one complete revolution clockwise (360 °). Now the begunok should indicate a label put on the case of the distributor. If the begunok is turned towards a conclusion of a candle of the 1st cylinder and the label of a pulley is combined with zero on a scale, the piston of the 1st cylinder is in VMT of a step of compression.

Prevention

If the begunok indicates a label put on the case of the distributor, and a label on the crankshaft and on a scale are not combined, or the gear belt is incorrectly established, or teeths of a belt slip on gear wheels.


13. After installation of the piston of the first cylinder in VMT of a step of compression it is possible to expose in the same situation and other pistons, turning the crankshaft and observing an operating procedure of cylinders. On the case of the distributor put the labels corresponding to high-voltage conclusions of candles of other cylinders, in the same way, as well as for the 1st cylinder, then number labels according to numbers of cylinders. At crankshaft turn the begunok will rotate too. If the begunok indicates a label on the distributor, the piston of the corresponding cylinder will be in VMT of a step of compression.
