Hydraulic compensators for VAZ-2107: design features and installation method
To ensure efficient operation of the engineit is possible to install hydraulic compensators. At VAZ-2107 installation of such devices is quite problematic, and expensive - the cost of rework is simply transcendental. But the noise decreases when the engine is running, all the knocking on the valve side goes away. But most importantly, you do not need to adjust the thermal gaps anymore. And on the "seven" and the machines of the "classic" series it is a disease - you need to adjust every 10-15 thousand km, otherwise the engine will die after warming up.
How Hydraulic Compensators Work
Hydraulic compensators on the VAZ-2107 allow forengine work to eliminate thermal gaps in the valves. The operation is in fully automatic mode, correction and any other adjustment is not required.
When repairing the timing mechanismjust change the valves and make them lapping. There are no washers or adjusting nuts in the structure. The engine oil moves to the hydraulic compensators, due to the pressure, the dimensions of these elements change. The valve moves under the action of a hydraulic type pusher on one side and a spring on the other.
Advantages of Hydraulic Compensators
If you install hydraulic compensators on VAZ-2107 car, you will get such advantages:
- The high-frequency sounds that appear when the engine is running out will be completely lost.
- The total noise of the motor decreases several times. Of course, the sound of the moving chain will still not be lost.
- The noise level from the engine in the cabin is reduced. If you drive at a speed of less than 80 km / h, there is almost no sound.
- The wear and tear of the elements of the gas distribution mechanism decreases, and significantly. Continuous shock loads that occur when there are gaps in the elements are lost.
- The integrity of the cams and rockers is preserved,regardless of the mileage. It is necessary to know how to check the hydraulic compensators yourself - this will improve the efficiency of their work.
- If you mount the hydraulic pushers on the timing mechanism, in which the rockers and cams on the camshaft are worn out, all the surfaces are gradually leveled.
- All motor parameters remain the same - powerand the acceleration does not change when installing the hydraulic pushers. But due to the fact that there is no difference in valve clearance, the engine runs as evenly as possible.
- If there is enough lubricant, all the elements of the hydraulic compensators have a huge resource - there is practically no wear.
For 20-30 thousand km of run after installation of hydraulic pushers, lapping of bushes and plungers occurs, their contacting surfaces acquire a mirror image. Subsequently, production does not appear, the dimensions do not change.
Disadvantages of using hydraulic compensators
The disadvantages of installing hydraulic compensators onVAZ-2107 is practically nonexistent. But one point should be taken into account - you need to use only quality oil and filters. When small particles enter the hydraulic pushers, a complete or partial failure occurs.
The size of the gap changes, which leads tothe appearance of loads of impact type. And they are the reason for reducing the resource of the mechanism. Similar consequences will occur in the event that the oil pressure in the system decreases. Therefore, if you decide to install hydraulic compensators on the VAZ-2107, you will only need to buy quality oil and filters, and also monitor the level.
What will be required to install the seven
In order to independently install the items on the "seven", you need to have tools and devices at your fingertips:
- Dynamometer wrench.
- A set of spanners (union, end heads, carobs).
- Drills and electric drill.
- Copper and steel wire.
- New gasket under the cover of the gas distribution mechanism.
- Angle grinder or several files.
- Rags.
- Fine abrasive grinding wheel.
- Set of hydraulic expansion joints.
- Frame for the head washers of the head.
- The mechanism for replacing the plungers.
Even before checking the hydraulic compensators, you need to prepare a special tool - without it, all the work is quite difficult.
Preparatory work
Preliminary preparation includes such manipulations:
- Dismantle the air filter housing and the element.
- Removal of a cable of a drive throttle заслонки. It is mounted on the cover of the gas distribution mechanism. It is possible to mount the hydraulic compensators on VAZ-2107 (carburetor). Not only they are put on the injector motors.
- Cranking the crankshaft so that the distributor is installed in such a way that the marks on the sprocket and body are aligned.
- Expand the washer under the sprocket of the camshaft sprocket.
- Unscrewing the fastening bolt.
- Unscrewing the fixing nut of the camshaft pastel, then dismantling it together with the rockers. Be sure to mark in which places they were installed - when assembling, mount them in the same way.
- Complete dismantling of the camshaft, unscrewing the adjusting cams.
After the preparatory work, it is necessary to cut down the tide, which is near the second valve - it will interfere.
Mounting of hydraulic compensators
It will be much easier to get in assembly of cylinder head with hydraulic compensators on VAZ-2107. But if you decided to do it yourself, then you perform such actions:
- All channels, through which oil is supplied, must be closed for the duration of the work.
- Install the bushes of hydraulic tappets.
- Press the washers of the block head.
- Press the O-rings into the hydraulic pusher plate.
- Fit the entire mechanism on the head.
- Install the springs and plungers, then put the actuator levers 4, 6, 7, 8 valves.
- Check the progress of the plungers and make corrections if necessary.
- In the pastel of the camshaft, you need to make a hole and put a tube in it.
- Install the hydraulic system so that all tubes are oriented correctly.
Typically, complete with hydropushers, there is a detailed instruction, which indicates the layout of the tubes for each type of engine.
