How to set the upper dead point without labels. Location of VMT marks on VAZ cars
The upper pulleys were not fixed, and now it is not clear how to exhibit them. Tags on the pulleys "watch" not quite in one direction. Maybe it's easier to trust all the pulleys for the provision of NMT in the cylinder 1? If we are talking about 16 valves, the setting of labels on the VAZ-2112 I know: I performed this operation on the timing of 21124. Well, I have a motor with a volume of 1.5. Are there any differences?
Exhibit timban tags correctly - otherwise you dampen the valve!
The VAZ-21124 engine has a feature: no matter how the pulleys would not be twisted, it is not. FROM Such jokes will not pass! If the positions of the pulleys are not bad, try to wear a belt and trust the mechanism to the "NTC 1 and 4" position. And now always use the instructions:
In theory, on the VAZ-2112, the settings of the labels are carried out equally, about what kind of motor it is not about. Here are a photo for the engine 21120.
How everything looks in reality and in the instructions
Do not be lazy to find the viewing window on the CATER CARTER. There is another label under the plug.
The last action is optional. And then perform it, so as not to redo all the work "from scratch".
Additional information:
- The number of belt teeth between the tags of the "upper pulleys" - exactly 16;
- The label on the crankshaft pulley is sometimes chips - use control by the "1" method (photo 1) or "3" (bottom photo).
Clarifications for VAZ-21124
On the motor with a volume of 1.6 all actions are performed in the same way as described above. There is one exception - the pulley of the generator drive is set on the label on the housing (see photo).
Moderator Drive Pulley, Motor 21124
However, if this label is not, use the proven method: 20 teeth are counted from the DPKV body. Instead of the 21st, there must be a "skip".
The timing pulleys can rotate, anyhow - the pistons in any case will not run for the valves. Compare how the pistons look two different motors - It will become clear what we are talking about.
Two different 16-valve
For those who do not understand
The number of teeth on the crankshaft pulley - 21, on the camshaft pulleys - 42. When the crankshaft is scrolled by 360 degrees, the camshafts rotate at 180. In general, the full cycle of the engine work consists of two crankshaft revolutions (720 degrees).
In theory, you can apply alternative method Settings. Let the labels of the camshafts look strictly down. Then the label on the crankshaft pulley should be drawn up (NMT 1 and 4).
If there is no fixing device, you can make it yourself. Even the reminder is suitable for (see photo).
They took and recorded
We wish you success.

A warning
The sequence of operations is presented in the assumption that the ignition distributor is set correctly. If you need to determine the upper dead point for setting the distributor, Install the first cylinder piston into the upper dead point in the compression tact, then set the ignition tags.
Top dead piston point - this is a point through which each piston passes when turning crankshaft. Each piston reaches the NMT position at the end of the compression tact then at the end of the exhaust cycle. In order to install the engine gas distribution mechanism, the top dead point of the first cylinder piston is used.
The location of the piston exactly in the upper dead point is extremely important when carrying out many works, for example, when removing distribution Vala, Promotion belt and camshaft pulley and ignition distributor.
Before starting work on installing the piston of the first cylinder into the upper dead point, make sure that the gear lever is in a neutral position, and hand brake tightened. Disconnect the ignition system by driving the central wire from the distributor cover and grounding it to the ground. Slide the spark plugs.
To install any of the pistons in the upper dead point, rotate the crankshaft with one of the methods described below. At the same time, rotate the crankshaft of the engine clockwise.
The most preferred method is to rotate the crankshaft of the engine for the crankshaft pulley mounting bolt.
To save time, you can use the starter to supply the piston to the top dead point. The exact installation of the piston in the upper dead point is carried out by turning the crankshaft for the crankshaft pulley bolt.

Installing the piston of the first cylinder to the NMT position of the compression tact
In order to carry out works associated with the removal of the camshaft drive belt, the installation of the gas distribution phases is not disturbed, the piston of the 1st cylinder is set to the NMT position (the upper dead point) of the compression tact. In case of violation of the phases of timber distribution, the engine will not work normally.
Set the VTM by a label on the camshaft pulley (when setting up the labels on the flywheel or the crankshaft pulley in this position may be a piston of either the 1st or 4th cylinder). After that, be sure to make sure the labels on the flywheel or the crankshaft pulley (if the pulley of the generator drive is removed). If the labels on the flywheel or pulley of the crankshaft do not coincide, it means that the installation of the valve distribution phases is broken (the piston of the 1st cylinder is not installed in the NTC).
In this case, it is necessary to remove the camshaft drive belt and turn the crankshaft until the labels are aligned.
A WARNING
Machine the crankshaft only for the attachment bolt to the pulley it (it is forbidden to turn the crankshaft for the pulley of the camshaft).
HELPFUL ADVICE
Since it is inconvenient to turn the crankshaft for the pulley attachment bolt, it can be done in the following ways:
1. Include any transmission (better than IV) and slowly ride the car before matching the label on the camshaft pulley with a label on the rear cap of the camshaft drive belt.
2. Enable any transmission and post one of the front wheels. Then rotate the posted wheel before matching the label on the camshaft pulley with a label on the back of the camshaft drive belt.
Tagged VMTs are applied on the gear of the camshaft pulley (protrusion) and on the back cover of the camshaft drive belt (mustache).
In addition, the labels are applied on the flywheel (risk) and on the clutch crankcase rear panel (triangular cutout). For clarity removed the gearbox.
Additionally, the labels are applied on the gear of the crankshaft pulley (dot) and the oil pump lid (triangular cutout).
These labels are visible only when the generator drive pulley is removed.
You will need: the "on 17" key key, the "on 10" key key.
1. Disconnect the wire from the minus terminal of the battery.
2. Install the gear shift lever to the neutral position, put the anti-digit shoes under the wheels of the car.
3. Remove the right front wheel And the right mudguard of the engine compartment.
4. Open the hood and remove the three screws for fastening the front cover of the camshaft drive belt. Note: Wiring holders are also fixed by screw mounting screws. Remove the front cover.
5. Turn the crankshaft for the fastening bolt to the generator drive pulley before matching the labels on the camshaft pulley and the rear lid.
6. Remove the plug out of the hole in the clutch crankcase and check the match match on the flywheel.

Exposing the labels, it should be borne in mind that the camshaft makes one turn for four engine clocks, and the crankshaft makes two turns.
Therefore, when combining the labels on the crankshaft pulley and the well on the cylinder block in the VMT, both the first cylinder and the fourth can be located.
You need to set the VMT by a label on the camshaft pulley (when setting up the labels on the crankshaft pulley in this position, the piston may be either the 1st or 4th cylinder).
After that, be sure to match the labels on the crankshaft pulley (when removed pulley Drive auxiliary aggregates).
If the labels on the crankshaft pulley do not coincide, it means that the installation of the phases of the gas distribution is broken (the piston of the 1st cylinder is not installed in the NWT). In this case, it is necessary to remove the camshaft drive belt and turn the crankshaft until the labels are aligned.
The crankshaft turns to check the coincidence of the tags for the attachment bolt to it by the pulley drive of the auxiliary units, removing the upper part of the right mudguard of the engine to access it.
In addition, it can be done in the following ways (especially when adjusting the gaps in the valve drive, when the check of the labels on the crankshaft pulley is not needed):
Enable any transmission (better than IV) and slowly ride the car before combining labels;
Remove one front wheel, turn on any transmission and then turn the woofer before combining the labels.
The label should match the label on the camshaft pulley with a label on the cylinder head cover made in the form of the Dachia logo.
And on the timing belt, the paint label is also applied, which should also coincide with the labels.
The label on the crankshaft pulley must be combined with the label on the cylinder block.
This label can be seen only after removing the pulley drive auxiliary aggregates.
To install the NTT, remove the right front wheel.

The setting of timing marks to VAZ-2108, 2109 and 21099 is necessary for proper synchronization of the crankshaft and the camshaft of the engine. It depends on whether the engine will be taken at all. Since these cars establishes the same engine 4-cylinder 8-cylinder valve, then in its example and consider the entire procedure for setting timing marks.
Where are the timing labels on the VAZ?
On the 8th valve Motor. VAZ one camshaft, it is much easier to set the labels than on the two-way. We will discern everything possible methods Find the extreme position of the camshaft and crankshaft.
In the camshaft, as a rule, there is a label on the pulley, such a small risk, and on the GBC there is a squeeze, with which this label must match, or rather not even squeeze, and the protrusion on the shield, on the left side, if you look at the engine and camshaft. Sometimes these labels are not observed, about how to do in this case, it is described below.
The crankshaft is set on the label on the flywheel, on the gearbox, near the engine from above there is a hatch, covered with a rubber plug. If you remove the plug, then we will see the risks on the flywheel and the protruding rod from the engine that must match. But then there may be a problem: the fact is that if the engine disassembled and the flywheel was filmed, then the flywheel can be put in any side, that is, the label will be damn it knows where, but not in VMT. There is no guide on the flywheel, nor the eccentric, which side will put, that he will become, at least 180 degrees of expansion.
In this case, you can search the engine in front of the engine - on the pulley and the retaliatory tide on the engine pump on the engine. But it is not on all engines such, often this label is missing. How to do in situations when the labels are not detected? It begins the most interesting, in fact, the labels on this engine are not needed, you can do without them.
How to set timing tags on vaz 2108, 2109, 2199, if there are no tags?
If the timing belt is not yet removed and you just need to make sure that the timing tag is installed correctly, unscrew the ignition candle to start, so that it is easier to turn the crankshaft. Then put the car on the jack, turning the front wheel, turn on the transmission and rotate the wheel, is the easiest way to turn the crankshaft.
Looking into the candle hole, you can see in what position is the piston, and if you turn the crankshaft there and slowly turn the crankshaft, then you can easily catch the NMT, looking at the dismay.
When NMT is defined in this method, removing the valve cover and see how the camshaft is installed, how it should stand below.
If the timing belt is already removed and it is necessary to set the position of the crankshaft and camshaft, it should be started to make sure that none of the pistons are in the upper dead point. It is necessary in order for when the camshaft was turned, the valves did not rush into the piston and did not get off.
Now proceed with the installation of camshaft in the desired position. To do this, we need to remove the valve lid and watch, in which direction the cams are watching. In this case, we are not interested in all cams, but only those that are responsible for the first cylinder, since we will set the first cylinder VTM.
At the very case, we do not have a special difference, which cylinder will put a camshaft when there are no tags. But if you take it to exhibit on the first cylinder, we will put it on it, especially since it is closest.
Under the valve lid, we will see the crankshaft, and there are a lot of cams (only 8, 2 cams per cylinder). The first two cams are our first cylinder. And we need to set the shaft in such a way that these two cams are simultaneously pressed on the valve. It will be NTC, overlapping valves. At the same time, the futtles of the fourth cylinder (two distant cams) will not be pressed on the valve, and they will look up the letter V. This is NMT. The beauty is that the camshaft itself is properly installed at the desired point under the action of the springs of the valves and does not go anywhere. Now you can install the crankshaft.
Now it is necessary to install the piston of the first or fourth cylinder in the NTT, without any difference what of which look, they move synchronously. It is better to shine a flashlight into a candle hole, the piston will be visible there. When the piston allegedly reaches the upper dead point, you need to insert something long in the candle hole, for example, scolding. While turning into a few degrees the crankshaft there and here, you can catch the NTM, the dye will get out to the maximum value. All, labels are set, you can wear the timing belt.
The timing belt is put on first to the crankshaft, then on camshaft, pulls the side as right as possible with the right side, and on the left side it is tensioning the tensioner roller.
