Lifters on the VAZ-2107: design and method of installation

To ensure effective engine operation, you can install the lash Adjusters. The VAZ-2107 installing such devices is rather problematic, and expensive – the cost of rework is just insane. But reduces the noise when the engine is running, leave all the knock from the valves. But most importantly – don't need any more adjustment of thermal backlashes. And "sevens" and the cars “classic” series, it is a disease – the adjustment should be done every 10-15 thousand km, otherwise the engine after warming up will stall.

How do hydraulic lifters

The Lifters in the VAZ-2107 allow when the engine is running to eliminate thermal gaps in valves. The operation is fully automatic, adjusting any other configuration is required.

In the repair of the timing enough to change the valves and make them grinding. No washers or adjustment nuts in construction is not provided. Engine oil moves to the lifters due to the pressure change of the sizes of these elements. Is offset from the valve under the influence of a tappet of the hydraulic type on one side and spring on the other.

The Advantages of hydraulic

If the car VAZ-2107 install the hydraulic compensator, you will receive the following benefits:

1. Completely lost high-frequency sounds that appear during engine operation.
2. Total motor noise is reduced several times. Of course, the sound of a moving chain still does not disappear.
3. Reduced noise level from the engine in the cabin. If you drive at a speed less than 80 km/h, the sound is almost there.
4. Decreases, and significantly, wear of elements of gas distribution mechanism. Lost permanent shock loads, which occur if there are gaps in the elements.
5. Preserves the integrity of Cams and rockers, regardless of the mileage of the car. Definitely need to know how to check the lifters themselves – this will improve the efficiency of their work.
6. To mount the hydraulic lifters on the valve gear, which is worn rockers and Cams on the camshaft, all surfaces are gradually aligned.
7. All parameters of the engine remain the same – power and the throttle response is not affected by the setting of hydrotalcite. But due to the fact that there was no difference in the clearances of the valves, running the engine as uniformly as possible.
8. In the presence of sufficient amounts of lubrication all elements of the hydraulic lifters have a tremendous resource – virtually no wear.

For 20-30 thousand km of run after installation of hydraulic pushers is lapping bushings and plungers, and their contacting surfaces become mirror-like. Subsequently, the output does not appear, the sizes are not changed.

Disadvantages of using hydraulic lifters

Faults when installing the lifters in the VAZ-2107 are almost there. But one thing to consider – you need to use only quality oil and filters. In contact with small particles inside the hydraulic tappets, there is a complete or partial withdrawal.

Changes the size of the gap, which leads to loads of shock type. And they are the reason for the decrease of the resource mechanism. The same effect will happen in that case, if you reduce the oil pressure in the system. Therefore, if you decide to install lifters on VAZ-2107, have to buy only quality oil and filters, as well as to monitor the level.

What you will need to install a seven

To undertake the installation of the elements on the "seven", you need to have handy tools and devices:

1. Wrenches.
2. Wrench Set (cap, socket head, carob).
3. Drill and drill.
4. Copper and steel wire.
5. New gasket under the camshaft cover.
6. Corner sander or some files.
7. Rags.
8. Melkoabrazivnymi grinding wheel.
9. Set of hydraulic lash.
10. The Frame washers for the head unit.
11. A Mechanism to replace the plungers.

Even before checking the hydraulic lifters, you need to prepare special tool – without him to be quite difficult.

Preparatory work

Advance preparation includes the following manipulations:

1. Disassembly of the air filter housing and element.
2. Removing the cable throttle actuator. It can be installed on the camshaft cover. You can make the installation of hydraulic lifters on the VAZ-2107 (carb). Not only on fuel injected motors they are placed.
3. Cranking the crankshaft to the distribution established thus to the alignment marks on the sprocket and the housing.
4. Razvaltsovannye washers under the mount camshaft sprocket.
5. Unscrew the bolt.
6. Unscrew nuts of fastening of pastels camshaft, its subsequent dismantling, along with the rockers. Be sure to mark where they were mounted – when assembling mount them exactlythe same.
7. Complete removal of the camshaft, twisting the adjusting Cams.

After the preparatory work you need to cut down the tide, which is near the second valve – it will prevent.

Installation of hydraulic lifters

Much simpler would be to buy a cylinder head Assembly with hydraulic lash Adjusters on the VAZ-2107. But if you still decide to change, then perform the following steps:

1. All the channels, which receives the oil, it is necessary during the works to close.
2. Set drive hydrotalcite.
3. Press washer head block.
4. Press o-rings into the plate of the hydraulic tappets.
5. Mount the entire mechanism on the head.
6. Install the springs and plungers, and then put the drive levers 4, 6, 7, 8 valve.
7. Check the stroke of the plunger and if necessary make adjustments.
8. Pastels camshaft it is necessary to make a hole in it to put your phone down.
9. Make installation of a hydraulic system to all tubing has been routed correctly.

Usually bundled with hydrotalcites there is a detailed manual that specifies the routing of the pipes for each engine type.
