How to remove the crankshaft pulley do it yourself

Alone, it is not only a reduction in expenses from the family budget, but also a great pastime. Each such motorist will sooner or later be faced with the problem of removing the pulley of the crankshaft of the car.

In most cases, the motorist thinks how to remove the crankshaft pulley, when it first faces the need to replace the sealing glands. Over the service life, they dry out, crack and begin to skip oil, and without removing the pulley, this task is not solved. At first glance, the task is not difficult to discharge, but as practice shows, in fact you may encounter some difficulties:

  • The pulley itself is deep in the engine compartment, behind the generator. At the same time, the work on the dismantling of the pulley is hampered by a small space, which is due to the design of the engine compartment of any car. In addition, when dismantling, you can damage other very important details, so you need to be extremely careful not to break anything else. In order to gain access to fastening and unscrew the crankshaft pulley, you need to loosen the tension bolts first, as well as remove the belts of the generator and GUR.
  • In the manufacture of a car at the plant, the pulley is very strongly tightened with nut or bolt. This is done for reliability of fasteners so that the pulley is accidentally unscrewed during operation. In addition, during the operation of the car, the pulley is tightened even more and the thread will deteriorate. Therefore, to unscrew it, you will need to make considerable efforts.
  • It should also be considered that when the clutch is turned off, the crankshaft freely rotates, which complicates the already difficult dismantling process. To unscrew the nut or bolt to which it is attached, it is necessary to secure it reliably. To do this, set the gearbox to the 4th speed and take care that under the wheels there is a reliable emphasis. In addition, it will not hurt to fix the handwheel of the crankshaft, the winding in his teeth.

As we have already written above, the crankshaft pulley can be fastened either bolt or nut.

We unscrew the Nut Shkiva

The nut is used mainly at the rear-wheel drive: classic VAZ 2101-2107 and Niva. To accomplish such a procedure, we will need an overpack or observation pit. First of all, stick the gearbox to the 4th speed and exit the handbrake. We will need the following tools:

  • the end key to 36 or 38 (depending on the construction of the fastener unit);
  • as a lever, you can use a mount or a piece of pipe.

If, using the lever, unscrew the nut still failed, we try the following:

  1. We put the checkpoint in the neutral position.
  2. We remove the povels.
  3. Remove the generator belt.
  4. We put the end key with the lever so that the end of him rests on the spar in the direction of rotation.
  5. If after that, then the short pulse must be rushing, why the nut must fly. If the crankshaft pulley does not work from the first time, you can try to do it another 1-2 times. Most often after this, the thread will weaken and the nut can be easily unscrewed by the usual key.

Remove the Bolt Shkiva

Bolt is used mainly in the design of front-wheel drive cars. In this case, the block is perpendicular to the axis. The process of unscrewing the bolt is a bit more complicated, because it is harder to get to it. To perform this operation, it is necessary:

  • jack, as well as a support element (peneta or goat);
  • face head (depending on the size of the bolt head installed on the pulley of your car);
  • the lever will suit the same as in the case of rear-wheel drive machines.

Now let's turn to the process of unscrewing the bolt, the order of our actions will be as follows:

  1. We raise the front part of the car by jack and install it on the "goat" (Penosek).
  2. Remove the front right wheel.
  3. We open the hood and remove all the details that prevent us from getting to the crankshaft pulley, namely the casing and air filter. You can also resolve other details that may prevent you from dismantling the pulley.
  4. Remove the generator belt.
  5. I carry the plug of the clutch block and insert the mount to the hole to join this the most teeth of the flywheel.
  6. Using the lever, we try to unscrew the crankshaft pulley bolt. If you lubricate it before this WD-40, then the process should go easier. In the case when manually unscrewed, it is not possible, you can try to perform steps with a short-term ignition on which we wrote above.

Dismantling pulley crankshaft

If you have already removed the bolt or nut from your crankshaft pulley, then further removal action will be much easier. In the absence of special tools, this can be made by the usual mount, alternately approaching it with one, then on the other hand. In this case, keep care and do not make excessive efforts so as not to damage the key and the groove.

Here we are with you and figured out how you can personally remove the crankshaft pulley. The process is not too complicated, but in any case, when you perform with your own hands, care must be taken. Be careful and attentive, and everything will succeed!
