Are you trying to remove the crankshaft pulley bolt without an impact gun? The task sounds complicated but is not impossible, especially if you’re faced with a lug nut. There are multiple alternatives you can use.

One of the simplest ways is to use a breaker bar and a socket to unscrew the nut. Similarly, you could use an impact tool if the car is small.  Find more details about this below.

Which Way Does the Harmonic Balancer Bolt Come Out?

Most engine nuts move clockwise, but companies like Honda and others have them moving in the anti-clockwise direction.

You can figure it out quickly by checking the course of the fan connected across the engine; both move in the same direction. That is important because the resistance will cause the breaker bar to move opposite to pry the nut loose.

How Do You Loosen a Crankshaft Pulley Bolt?

To loosen a crankshaft pulley bolt, you need the right tools. Although using an impact wrench is the easiest, most efficient method to get the job done, a breaker bar can do the same work if used properly.

Impact gun makes the entire task faster and works by producing sudden rotations to move the lug nut every few seconds. It uses both sources: electricity as well as the air motor. Using an impact gun with electricity is feasible, but an air motor offers quick and seamless output. It can pull open every type of lug nut, irrespective of how hard it may be stuck.

Meanwhile, using a breaker bar is better, especially if you’re a beginner. You can get it from any local warehouse or online. However, if you can’t arrange a breaker bar, a ratchet could also come in handy.


  1. Fit the right-sized socket in the bolt and place the bar in it. Before moving the bar, check the rotation of the bolt. The wrench will move in reverse rotation of the bolt and loosen it.
  2. Once you’re done, wedge the wrench to any strong part of the engine, either by a rope or by sticking it in the axle since it’s pretty firm. That’s because the starter gives a jerk which could cause the bar to fly if not fastened tightly.
  3. With everything in place, turn the ignition, and the engine will give a sudden jolt. The force delivered from the engine will cause the crankshaft to vibrate and move the breaker bar. Since the breaker bar was tightly attached, it will repel the movement, and the nut will come out. Even if it doesn’t come out itself, it will be loose enough to be pulled out.


The average breaker bar might not fit in a pulley bolt if you’re dealing with a large car. So, it’s better to get a special crankshaft puller. If the nut is in bad shape and the task requires more time, you might want to remove the motor from the engine and work on it separately.

It will save you the backaches from leaning over the car for hours. That is the most convenient method and works every time on every vehicle.

Next, remove the crankshaft pulley once you’re done removing the bolt. It is pretty easy to remove when using the main pulley and bolts to turn it out. But you can take it out even without the right tools. All you need is a belt and breaker bar or a ratchet.

How Do You Remove A Crankshaft Pulley Without A Tool

Secure the belt somewhere near the groove by tucking it in or fixing it against itself. After this, attach the breaker bar and look out for the direction of rotation. When the belt is settled in its place, move the bar multiple times until the nut budges. Use a wrench to loosen the nut and remove it.

The belt used might get a slight kink in it because of the immense resistance it had to put up with. But that should not affect its usefulness since the bolt is what has been holding the pulley in place. Upon removing it, the pulley becomes loose. You have removed the crankshaft pulley without spending a penny or using any tool.
