If the knowledge and experience of the motorist is sufficient, the temporary disassembly costs do not exceed 15 minutes. In the opposite case, this process can delay no time. In the absence of due information, significant difficulties arise. They are available even if there is information (instructions) on how to properly carry out maintenance.

How to unscrew the crankshaft pulley

Difficulties begin when establishing a crankshaft in a fixed position.

The dismounting process is quite time-consuming, the rotation of the part does not allow it to fix it.

Most get into the stupor at the stage of approach to the bolt, which determines the place of the pulley.

Difficulties when removing it adds its prolonged, contributing to the damage of the elements of the engine compartment and the coating of the body.

Both manufacturers and specialists of the technical center of nuts or bolts, depending on the model, is carried out with the ultimate rigidity.

The purpose of these actions has its own logical explanation.

If the elements are poorly twisted, then the likelihood of their spontaneous attenuation at the time of operation of the vehicle is large.

Thus, if the nut or bolt leaves its location, restore the performance of the vehicle, to continue the path, it is quite difficult.

The costs of recreating the previous state will not be small.

The operation of the engine, in the event of a prolongedness of the elements, acts as an additional fastening mechanism, since at the time of its operation, the tightening rigidity rises.

Fastening is enhanced when corrosion processes, sticking and coking occur.

Revealing Bolt Shkiva

Most bolts are fixed by the pulleys of cars that have front-wheel drive.

To get to the pulley, in such vehicles, it is quite difficult, because its location relative to the axis of the car perpendicularly.

To facilitate work and saving time, there must be the following elements:

-Complek car tools;

- "Penc", a means substituted under the vehicle;

-jack;

-Rechag and end head, selected by the size of the bolt.

Prepare the above devices, the following activities are carried out.

Nuts of the right wheel are unscrewed.

After that, the jack is raised the same side of the car. The rejected wheel is removed.

Then, "Penc" is used, which is led by the car.

The following is required to make a dismantling of the engine torch, providing protection against dust and dirt.

From the side of the hood, at the top of the generator belt and the air filter are removed.

In the clutch block area there is a plug that needs to be opened. With mounting, the mobility of the flywheel is eliminated, which will allow the crankshaft in a fixed state.

Fixing its position, you can start unscrewing the bolt.

If the process is not shifted from the place, then it is necessary to increase the length of the handle (lever).

Revealing nut pulley

It is more expedient to apply it, as an extension, a metal pipe of considerable length. Using a cape or end key, the diameter of which is 36 or 38 mm, for the means of the lever and the pipes are weakened by the nut. Mainly nuts are attached to vehicle pulleys that have rear-wheel drive.

It has special protrusions.

To dismantle the nut, we sit, with prepared tools, under the car.

Thus, the process of unscrewing is carried out.

If the process stalled, we take the following actions.

Neutral transmission is set, the adversals are dismantled, the design of the lever and the pipe is put in the position of the stop of the floor.

Here the impulse is sent by means of rotation of the ignition key. Having done it, the nut is usually easily unscrewed.

To simplify the task of removing the pulley there is a device.

It looks like a nut equipped with a hairpin.

It has three captures. So, in the process of work, the hairpin creates an emphasis in the central part of the shaft, three captures are attached to the edges of the pulley.

This allows without visible difficulties to remove the pulley from the shaft, rotating the device clockwise with a stud.
