How to determine exact cylinder VTM. Installation of the first cylinder in VMT (Lada Largus). The ignition is incorrectly configured
Often on autofors of newcomers, motorists are looking for an answer to the question - how to find tags on the flywheel? At the same time, rarely meet the right recommendations on this topic. Let's try to figure it out specifically, give valuable advice.
ATTENTION! Found a completely simple way to reduce fuel consumption! Do not believe? Auto mechanic with 15 years old also did not believe, until he tried. And now it saves 35,000 rubles per year in gasoline!
The label to set the moment of ignition or VTT on the flywheel is thin, as if scratched intoxid. There is a label not on the crown, naturally, and on the mirror of the element (smooth plane). Unfortunately, this label often rusts, and the motorist is useful occasionally clean it with a screwdriver or seer.
Simultaneously with this label, wells or recesses are provided on the mirror. These are also special risks intended for the competent installation of the flywheel on the tip of the crank shaft.
See the labels on the balancing of the crank shaft, if nothing is disassembled from the car (the box is not dismantled), it will be possible through a special hatcher. Of course, you need to use the help of the assistant, without this in any way. One person must rotate the crankshaft quietly, the other is to follow the labels. It is necessary to watch under good lighting so as not to miss the desired label. If the lighting is not enough, use the flashlight.
The label of the flywheel is more correct to call the risk. There are several types of labels, and risk cannot be confused with the rest.
For example, on the 8-valve engine of the domestic "eight" and later auto industry models there are Tags of the following type:
- on the camshaft star (the label resembles the protrusion);
- from the back side of the lid of the drive belt (more reminiscent of the mustache);
- on flywheel (risk);
- on the rear side of the clutch crankcase (similar to the triangle);
- on the pulley of the crank shaft (reminds of the point);
- on the lid of the oil pump (triangular cutout).
The last two labels are visible only after removing the pulley of the generator drive. Triangle-cut cutter clutch is better viewed after removing the checkpoint.
But on the 16-valve power installation The domestic 21126 tags, except the above, are still in the following places:
- on stars of both camshafts in the form of protrusions;
- from the back side of the lid of the camshaft drive (triangle cut).
Reference. Car flywheel - this is a special detail mechanical typeMade in the form of a disc. It is fixed by bolts to the rear tip of the crank shaft, serves for the most part To preserve inertial energy.
Why do I need a label of flywheel
In particular, for this label, it is possible to set the VMT, which, in turn, helps competently install, for example, the timing belt. Inclinence of marking labels leads to disastrous consequences - it should always be remembered.
A step-by-step algorithm for setting timing marks looks about as follows:
- the desired toolkit is prepared, which includes a flat screwdriver, the "top ten" key and the lift;
- then the right side of the car rises using a jack;
- the protection of the GRS mechanism is removed under the hood of the vehicle;
- the wheel rotates until the camshaft does not coincide with risks on the GBC and the crank shaft pulley.
That's where the "flywheel time" comes. If its label does not coincide with the housing (block), then all the manipulations performed above are the price. To see the label will turn out through the hole, it will be necessary to remove the plug in advance with the gearbox.
The label of the flywheel must coincide with the block. The assistant must rotate the crankshaft, the car owner - look carefully.
Adjust the same label, if torn drive belt Or setting up after the repair of the GBC.
Installation of labels on the power unit of the car helps to properly set uzov, coordinate the work of the GRS mechanism and the injection system.
A couple of important nuances
That's what I would like to pay attention to:
- to turn the crank shaft is followed exclusively for the bolt of the pulley fixator (in no case for the pulley itself!);
- you can also turn the crank shaft and so: put one of the gears of the checkpoint (better than the 4th), push the car before combining the labels, or hang one of the wheels - and twist.
Balancing
Of course, the element label (risk), put up by the mind, will become effective only in the case of an ideally smooth flywheel. If an element imbalance is observed, it will have to carry out balancing. The Balancing Task List will also find the flywheel radius.
Unfortunately, the stand balancing is not available in every city. On such a machine it is easier to adjust the crank shaft and flywheel.
Balancing either on a special mandrel, or on the shaft itself (not removed). The main action that is carried out at balancing is relief. Some metal layer is removed from the flywheel to adjust the correctness of its mass. You can only remove the layers from the edges, the center of the part must remain integer so that the strength characteristics of the part are not to be reduced.
Important moment. Before you begin balancing the flywheel, you need to perfectly balance the crank shaft.
Excess weight with flywheels is removed by drilling. The layers are removed in several goals until the correct rotation is adjusted.
Watch out for the cleanliness of the flywheel. If it is possible to remove the item, then do not be lazy to carefully examine it on defects. The risk of the flywheel regularly clean from dirt so that in the future it would be clearly visible.
The piston of the 1st cylinder of Lada Largus is set to the NMT position (top dead dot) of the compression tact in order for the operation associated with the removal of the camshaft drive belt, the installation of the phases of gas distribution is not disturbed. In case of violation of the phases of timber distribution, the engine will not work normally. On the engines of cars Lada Largus, unlike engines of most car brands, the countdown of cylinders is conducted from the flywheel, and not from pulley crankshaft. Exhibit VMT by tags on pulleys distributional shafts (When set to labels on the crankshaft pulley in this position, the piston of either 1 -th or 4th cylinder may be located.
The crankshaft turns to check the coincidence of labels for the attachment bolt to the actuator pulley auxiliary aggregatesAfter removing it to access it the upper part of the right mudguard of the engine. 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):
1) Include any transmission (better than IV) and slowly ride the car before combining labels;
2) post one front wheel, Turn on any gear and then turn the wheelchair until the labels are aligned.
Tools for installing the first cylinder of Lada Largus in VMT
You will need: end keys (heads) "on 10", "at 18".
Operations for the installation of the first cylinder of Lada Largus in the VMT
To install the piston of the 1st cylinder of the K7M engine to the NMT clock position, follow the following.
1. Remove the right front wheel. Weaken the tightening of the wheel fastening bolts only on the car standing on the ground. If you work on the viewing ditch or overpass, put stubborn bars under the wheels, slow down the car at the parking brake and install the front of the car on a reliable support.
3. Remove the drive belt of the auxiliary units (see "").
4. Remove the right support suspension power aggregate (cm. " ").
5. Remove five fastening bolts top cover The drive belt of the gas distribution mechanism ...
6. ... And remove the lid.
7. Turn the crankshaft clockwise per pulley attachment bolt ...
8. ... Before combining the label on the gear of the camshaft with a label on the cover of the cylinder block, made in the form of the Dacia logo. In addition to labels on a pulley, a risk A, which, when installing the gas distribution phases, should also be combined with a label on the pulley during the installation of Thase distribution.
9. Remove the bolt attachment of the pulley drive auxiliary units ...
10 ... and remove the pulley
11. Check the coincidence of the labels on the crankshaft pulley and on the cylinder block. If the labels 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 set to VTC). In this case, it is necessary to remove the camshaft drive belt and turn the crankshaft until the labels are aligned.
To install the piston of the 1st cylinder of the K4M engine to the NMT position of the compression clock, follow the following.
You will need: the end heads "at 15", "on 18", TRX 14, the key "on 13", a screwdriver with a flat blade ...
crankshaft latch
and fixture of distributional shafts.
Fig. 1 Lada Largus crankshaft lock
Fig. 2 Captation Valley Fixer
In the absence of special fixtures, you can make them according to the sketches shown in Fig. 1 and 2.
1. Remove the right front wheel.
2. Remove the top of the right engine right mudguard
3. Remove the drive belt of the auxiliary aggregates (see "Replacing the drive belt of the generator and pump").
4. Remove the right support suspension of the power unit (see "Replacing the right support of the suspension of the Lada Largus power unit").
5. Remove the three bolts A and unscrew the two nuts used the top cover of the gas distribution mechanism.
6. Remove the top cover of the drive belt of the gas distribution mechanism.
7. Rotating the crankshaft clockwise for the pulley attachment bolt ...
8. ... Install the labels on the plugging pulleys with the "Renault" logo so that they do not reach the top point.
9. Remove the TRX E14 head plug hole for setting the crankshaft clamp. The cork is located on the cylinder block in front of the movement of the car, in the area of \u200b\u200bthe 1st cylinder.
10. Screw the crankshaft lock in the hole.
11. Blast the engine crankshaft until it stops.
In order to fix distribution shafts in VMT, perform the following operations.
1. Remove the inlet noise muffler (see "Replacing the air filter filter element").
2. Patty a screwdriver with a flat blade of the plugs of distribution shafts ...
3. ... and email them from the back of the head of the cylinder block. Distributional shaft plugs When assembling, replace new.
4. Ply proper installation Piston 1 -to cylinder to the NMT position of the groove compression tact at the ends of the camshafts should occupy a horizontal position and be shifted down relative to the axis of the distributional shafts.
5. Secure the camshafts in this position by the distribution shaft fixture. If the grooves occupied the wrong position and install the lock is impossible, 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 reinstall the drive belt of the gas distribution mechanism.
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 an alternative setup method. 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.
Check timing timing on one video
1. The top dead point (NTT) is called the highest point of the piston stroke in its cylinder. In 4-stroke engines in the process of rotation of the crankshaft, this position is achieved by each of the pistons twice within one working cycle: once at the end of the compression tact and the second - at the end of the graduation cycle. Determining the position of the piston at the end of the compression tact (usually the first cylinder) is important for many work performed further, for example, to replace the toothed belt, checking the phases of gas distribution and replacing the cylinder head gasket. Sometimes NMT compression tact is also called the point of ignition.
Note: Cylinder numbers are considered in a sequence of 1 to 4. The first cylinder is located on the drive side of the auxiliary aggregates / GD drive.
2. In this section, the installation procedure of the first cylinder of the engine 1.6 L Z16XEP is most fully described. For other engines, only the features of NMT setting are given. When working, some special tools and devices of Opel will need, make sure that all the necessary accessories are available and are at hand.
3. To bring the piston of the first cylinder to the VMT, it is necessary evenly and slowly rotate the crankshaft so that the labels of the NMT are coincided. Depending on the conditions, the rotation of the crankshaft of the engine can be performed in the following ways:
- Post and install the front of the car on the stands. Turn on the 5th gear - when moving one of the elected wheels, the engine crankshaft will be rotated (models with RCPP). To turn the wheel when conducting adjustments, use the assistance of the assistant.
- If there are no fixtures for improving the car at hand, choose a smooth largest platform and turn on the 5th transmission. When moving the car by pushing the crankshaft (models with the RCPP) will turn.
- In stationary conditions, the twist of the crankshaft is carried out using a ratchet key and a shift of the head, which is installed on the central bolt of fastening the crankshaft pulley, it must be enabled neutral transmission And crushed parking brake. The crankshaft should be rotated clockwise (if you look from the timing side of the timing).
