The crankshaft pulley bolt is one of the most important bolts on your engine. If it comes loose, the engine will not be able to function properly. The crankshaft pulley bolt must be tightened to the correct torque in order to keep the engine running smoothly.
Here is a step-by-step guide on how to tighten a crankshaft pulley bolt.
- Park your vehicle on a level surface and set the emergency brake
- Place a block behind one of the rear tires to prevent the car from rolling when you loosen the crankshaft pulley bolt
- Locate the crankshaft pulley at the front of the engine
- The crankshaft is the shaft that the pistons connect to and it rotates as the engine runs
- The crankshaft pulley is usually made of aluminum and has grooves machined into it for each of the accessory drive belts
- Wipe any dirt or grease off of the center bolt that secures the pulley to the crankshaft with a clean rag before proceeding
- Insert a 3/8-inch drive ratchet into one of the holes in either side of
How to Tighten Harmonic Balancer Bolt
If your car has a harmonic balancer, then you know that it’s an important part of the engine. The harmonic balancer bolt can sometimes come loose, which can cause serious engine problems. If you notice that your harmonic balancer bolt is loose, then you’ll need to tighten it as soon as possible.
Here’s how to do it:
1. Remove the old bolt and washer from the harmonic balancer. You may need a wrench or socket to do this.
2. Clean the threads on the harmonic balancer with a wire brush. This will ensure that the new bolt will have a good grip.
3. Place a new washer over the threads and screw on the new bolt.
Tighten the bolt until it’s snug, but don’t overtighten it.

How Do You Tighten a Crankshaft Pulley Bolt Without Impact Gun?
Most crankshaft pulley bolts are torqued to between 18 and 30 foot-pounds of torque. To properly torque a crankshaft bolt without an impact gun, you will need a torque wrench that is calibrated in inch-pounds, rather than foot-pounds. You will also need to be sure that the bolt is lubricated with either motor oil or anti-seize compound before attempting to torque it.
To begin, attach the appropriate size socket to your torque wrench. Next, position the socket over the crankshaft bolt head and insert the ratchet handle into the square drive of the socket. Slowly turn the ratchet handle clockwise until you reach 18 inch-pounds of torque.
At this point, continue turning the bolt another 1/4 to 1/2 turn to ensure that it is properly seated. Finally, remove the socket and ratchet from the bolt head.
How Do You Tighten a Camshaft Pulley Bolt?
If your car has an interference engine, the camshaft pulley bolt must be torqued to a specific value. If it isn’t, you risk damaging the engine. To properly torque the bolt, you’ll need a torque wrench and either a socket or an open-end wrench that fits the bolt.
The first step is to remove any oil or grease from the threads on the bolt. Next, thread the torque wrench onto the bolt and turn it until it clicks. This is your starting point.
Now, using either the socket or open-end wrench, turn the bolt clockwise until it’s tight. Finally, use the torque wrench to ensure that the bolt is tightened to the proper value. With an interference engine, this value is usually between 20 and 30 ft.-lbs.
How Do You Loosen a Tight Crankshaft Pulley Bolt?
Over time, crankshaft pulley bolts can become extremely tight, making it difficult (or even impossible) to remove them. However, there are a few methods you can use to loosen a tight crankshaft pulley bolt.
One method is to use an impact wrench.
An impact wrench is a power tool that uses compressed air or electricity to generate a high amount of torque, which can be used to loosen stubborn bolts. If you don’t have access to an impact wrench, you can try using a breaker bar. A breaker bar is simply a long handle that gives you more leverage than a regular ratchet wrench.
Simply attach the socket onto the bolt and then turn the breaker bar in the direction of loosening.
Another method is to heat up the bolt with a torch before attempting to remove it. The heat will help expand the metal and break any rust that may be holding the bolt in place.
Just be careful not to overheat the surrounding area as this could damage other components.
If all else fails, you may need to resort to drilling out the oldbolt and replacing it with a new one. This should only be done as a last resort as it will permanently damage the crankshaft pulley.
How Do You Fix a Stripped Crankshaft Bolt?
If you have a stripped crankshaft bolt, the first thing you need to do is remove the old bolt. This can be done with a drill and an extractor bit. Once the old bolt is removed, clean out the hole in the crankshaft with a tap and die set.
Next, insert a new bolts into the hole and tighten it down. Finally, torque the new bolt to specifications.
