Subsequently, one may also ask, where is the crankshaft pulley?

The crankshaft pulley is bolted to the harmonic balancer and turns the belt, or belts, to operate other engine components like the alternator or air conditioning compressor. It is located at the end of the crankshaft near the bottom of the engine.

Beside above, how do you remove crankshaft pulley? Disassemble the crankshaft pulley You just have to place one end on the bolt-removing tool and slacken the bolt using an impact wrench. With the bolts included in your tool, you may now tighten the bolt remover tool. Keep doing this step until the crankshaft pulley is finally released.

Beside this, how do I know if my crankshaft pulley is bad?

Bad Crankshaft Pulley Symptoms

  1. 1) Engine Vibrations. The first symptom that will likely come up are engine vibrations.
  2. 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator.
  3. 3) Power Steering Pump Failure.
  4. 4) Transmission Damage.
  5. 5) Irregular Idle Engine Speed.

Is the crankshaft pulley supposed to turn?

The camshaft and crankshaft pulleys are directly attached to the engine (camshaft and crankshaft) and will only rotate if the engine is running or manually rotating the engine by placing a socket and breaker bar to the crankshaft pulley bolt.

Can you drive with a bad crankshaft pulley?

Indeed, if it's the crank pulley and the harmonic balancer comes off with it and the engine continues to run that can damage the crankshaft. That would be very bad. Other pulleys could get distorted if a fastener is missing and in such condition could damage the drive belt riding on the pulley.

What causes a crank pulley to wobble?

Perhaps when they were installed (or re-installed following service), some dirt was trapped under the pulley and/or they were torqued improperly, causing the wobble. With the fan-belt pulley removed you'll be able to examine the harmonic balancer more closely for damage.

What does a bad harmonic balancer sound like?

A worn-out crankshaft harmonic balancer will also cause a lot of noise in your engine. You will feel this noise once you start to accelerate your car to higher speeds. If this noise is too loud, it is better to not drive the car and call a mechanic.

What happens if harmonic balancer breaks?

If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.

How do you test for a bad harmonic balancer?

Start your engine and check the harmonic balancer to see if it wobbles while the engine is running. Take a flashlight and shine it directly onto the balancer to see if it goes in and out while rotating. If it wobbles, the harmonic balancer is bad. Turn off the ignition.

Can you drive a car with a bad harmonic balancer?

It's not okay to drive with a bad harmonic balancer. The bouncing crankshaft will wear on the main bearings. It can also tear up drive belts and possibly come apart posing a danger to people and property.

Why do harmonic balancers fail?

If the rubber layer in the harmonic balancer dries or wears out, it can cause the entire harmonic balancer to completely fail by separating. If the harmonic balancer separates, the engine belts will usually come off and the vehicle will be left without engine accessories.

How do you balance a crankshaft?

The big end of the rods and the rod bearings rotate around the crankshaft centerline, and therefore represent the rotating mass. During the balancing process, bobweights are bolted to each rod journal to simulate the mass of a pair of pistons and rods.

What does the crankshaft look like?

Without crankshaft your vehicle won't even move an inch though your engine will be running. This is how a crankshaft looks like: This is how a crankshaft looks like: You will agree that due to combustion of fuel in the cylinder, energy is generated and due to this the piston moves downwards during the power stroke.

Can you turn crankshaft backwards?

When a motor is turned backwards, the timing relationship between the crank (timing mark) and the cam (distributor, etc) changes, so parts can be installed out of time, etc. You can turn it backwards, then just need to turn it back forwards enough to remove the slack, restore the timing relationship.
