Step #1: Remove the Alternator/Serpentine Belt

Firstly, remove the alternator belt, also called the serpentine belt. For his, you’ll have to stand in a proper position and reach the crankshaft damper/harmonic balancer. Then, unscrew the car engine cover screws with the proper ratchet.

Secondly, find the alternator belt underneath the tensional springs to apply pressure on the belt, which helps to make sure it’s firm. Next, use your torque wrench socket to press the tensioner toward the opposite direction of the tensional spring to release it. Lastly, pull off the belt from any pulley closer to it.

Step #2: Locate and Remove the Crankshaft Pulley Bolt

The crankshaft pulley bolt is located in front of the crankshaft, and it holds the crankshaft to the harmonic balancer. You can only remove the bolt with the correct socket size. Dropping some penetrating oil on it will help loosen it, and turning the bolt by force can damage your car oil pump. Once the bolt is finally released, carefully pull off the harmonic balancer and place it firmly on a smooth surface.

Step #3: Remove the Crank Pulley

Today, modern car engines feature a pulley that keeps the harmonic balancer away from the center bolt. So, remove the crank pulley by rotating the center bolt slightly with a screwdriver, and then pull it out with a pickle fork. Although you can use your bare hands in place of a pickle fork, it is safer to use a tool in order to avoid getting injured.

Step #4: Remove the Crankshaft Pulley

Most people prefer to use a crankshaft pulley tool to remove a bad crankshaft. Yet, you can use a socket and a cheater bar to remove your vehicle’s crankshaft pulley. Also, opt for this route whenever you don’t have access to a pulley tool.

Then, fix the socket into the bolt and stick it in the cheater bar at the end of the socket. Ensure to set it in firmly. Afterward, move the cheater bar parallel to the car engine’s direction.

Make sure to wedge the bar on a hard surface in the engine compartment. When the bolt starts to move, turn on your car ignition to help loosen the pulley bolt. You can use a strong screwdriver behind the crankshaft to carefully pull it out.

Final Words

Trying to manage your damaged crankshaft can cause severe damage to your vehicle. For example, a bad crankshaft pulley can cause a power steering failure, faulty timing belt, alternator failure, engine vibration, irregular idle speed, etc. Therefore, instead of ignoring the problem, replace the crankshaft pulley as fast as possible with the right tool. Prolonging the time before taking action leads to a bigger risk of an accident taking place.

Some cars may have different serpentine belts, depending on the model. Regardless, follow the first steps of this guide since they’re mostly universal. When doing so, make sure you identify each part correctly before meddling with it. However, if you feel too inexperienced for such a task, perhaps consider heading to the nearest auto repair shop.
