How To Remove Crankshaft Pulley Without A Puller?

Have you ever imagined what a bad crankshaft pulley can be like in your vehicle? It’s horrible right? Since the crankshaft pulley is connected to the harmonic balancer, which is responsible for absorbing vibrations of your car’s engine during faster acceleration while you drive, a bad crankshaft pulley will alter the harmonic balancer’s ability to absorb your car’s engine vibration as you accelerate faster while driving.

Suppose you have also experienced power steering pump failure, alternator failure, and irregular idle engine speed. In that case, these are signs that you need to replace your vehicle’s crankshaft pulley, which is most likely responsible for those challenges.

Among many components of your car’s engine, the crankshaft pulley is a vital component due to its responsibility of distributing engine power to other systems of your car. If you have a bad crankshaft pulley that needs to be replaced and you don’t have a pulley removal tool, sufficient information has been provided on how to remove crankshaft pulley without a puller.

Step 1: Take off the serpentine belt

First of all, you need to remove the serpentine belt, also known as the drive belt or accessories/ alternator belt, to access the harmonic balancer. To do this, take off the car’s engine cover, and the shrouds or plastic guards used to cover the engine working area. Then, locate the serpentine belt beneath the spring tension to exert pressure on the belt, which helps ensure that it is secured.

After that, use a wrench socket to push the tensioner towards the opposite direction of the spring to enable its release. Shift the belt off the pulley closest to it. Then proceed to remove the drive belt from the pulley at the bottom and other pulleys. This is also the first step on how to remove harmonic balancer.

Step 2: Identify the center bolt

The center bolt can be found in front of the crankshaft. It is responsible for holding the harmonic balancer in its position. The center bolt is very tight, and you would need some other tools to enable you to loosen it.

Step 3: Loosen/remove the center bolt.

Use a socket to loosen the center bolt by breaking free the bolt with a hammer after placing the socket on the bolt. If this isn’t working, you can as well place the socket on the bolt tightly and start the car’s engine to rotate and loosen the bolt. This strategy works faster when the bolt is very tight.

Step 4: Remove the crankshaft pulley

Although most people use a crankshaft pulley removal tool or a puller for removing a bad crankshaft, you can also use a cheater bar and a socket to remove the crankshaft pulley. Fix the socket on the bolt inside and stick the cheater bar on the end of the socket. Then, snap it in. Turn the cheater bar in the same direction as the engine. Ensure to find out which way the car’s engine turns.

Endeavor to wedge it against a solid metal in the engine compartment. As you crank the engine, the bolt will start to turn since the bolt holds the crankshaft pulley as a right-hand thread. After that, put your car key in the ignition and turn it. By doing this, it will loosen the crankshaft pulley bolt. You can take the bolt off by hand once it loosens.

You can now use a big screwdriver behind the crankshaft pulley to carefully drag it out. You may also use a ½” or ¾” powerful impact gun to hammer it out.

You can also follow the step-by-step guide above if you are wondering how to remove a harmonic balancer without a puller. The information above also provides a glimpse of how to remove a power steering pulley without a puller.
