What happens when the crankshaft pulley goes bad?
But if the balancer starts to go bad for any reason, the vibrations won’t be absorbed anymore. This will cause the engine to shake profusely the faster you go. 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator. So naturally, if the crankshaft pulley goes bad, then you can expect the alternator to stop working.
Where is the pulley located on a crankshaft?
A crankshaft pulley is a disk mounted to the end of your vehicle’s crankshaft. As the pistons fire and power the shaft, the pulley turns and operates a belt. This belt drives many of your vehicle’s accessory components: This part might also go by several other names, including harmonic balancer and crank pulley damper.
How can I tell if my idler pulley is frozen?
To find out if you have frozen idler pulley or a pulley that is hard to spin, you will have to slip or remove the engine drive belt from the idler pulley. Observe caution when removing the drive belt off the idler pulley. Make sure the engine is not running. Remove the car key from the ignition just to be sure.
How much does a new crankshaft pulley cost?
That’s because some pulleys also smooth out engine function and dampen vibrations, depending on the make and model of the vehicle. How much is a replacement crankshaft pulley? That’s why they can cost anywhere between $40-500 on average. Make sure to buy new drive belts to put in while you’re reinstalling your pulley.

How does an idler pulley keep the engine in place?
The pulley prevents this belt from ever slipping out of its position. The idler pulley may have a smooth outer wall, but the edges typically have retainers while some may have a middle groove to keep the drive belt in place. We know that an idler pulley rotates on its own shaft, moving the engine drive belt along its route.
What to do if pulleys don’t track properly?
Tighten mounting. Check level and alignment of pulley shaft or belt will not track properly. If bearing is excessively worn, replace with new bearing. Check fit of inner race to ensure against bearing distortion. Check level and alignment at pulley shaft. Check shaft for straightness. Remove pulley to replace shaft.
How much does it cost to replace a crankshaft pulley?
Replacement Cost. The cost to replace a bad crankshaft pulley is anywhere from $350 to $400. The cost of labor is around $150 to $180 and the cost of parts is around $200 to $220. It is not the most expensive replacement job, but it is not too cheap either.
What happens when the crankshaft position sensor goes bad?
If the computer detects a problem with the crankshaft position sensor’s signal, it will activate the Check Engine Light to alert the driver of the problem. A Check Engine Light can also be set off by a wide variety of other issues. Having the computer scanned for trouble codes is highly recommended. 4. Uneven Acceleration
What causes a crankshaft harmonic balancer to fail?
Separated harmonic balancer. 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.
What are the symptoms of a bad crankshaft position sensor?
Common signs of a faulty crankshaft position sensor include issues starting the vehicle, intermittent stalling, and the Check Engine Light coming on. Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on.
What are the symptoms of a bad crankshaft harmonic balancer?
Symptoms of a Bad or Failing Crankshaft Harmonic Balancer. 1 1. Engine vibration. One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is 2 2. Misaligned timing marks. 3 3. Separated harmonic balancer.
Is a crankshaft pulley the same as a harmonic balancer?
A harmonic balancer (sometimes crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator,…
What are the signs of a broken crankshaft?
The most common symptoms of a bad or failing crankshaft position sensor are that your vehicle may not start or your engine will stop while driving. You can also experience misfires and a Check engine light flashing on your dashboard.
What causes a crankshaft pulley to wobble?
What causes the crank pulley to wobble. A bad harmonic damper on the pulley would result in it wobbling and only solution is to replace the pulley, which should be done asap as failure of the pulley can result in the drive belts getting entangled and if the belts were to get to thr timing belt, it can damage the engine.
What is a crankshaft harmonic balancer?
The crankshaft harmonic balancer is a device connected to the front of an engine’s crankshaft, usually built into the crankshaft pulley. Its purpose is to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates, as harmonic vibrations at high engine speeds can cause accelerated wear and damage to the components.
What to do if you have a crank shaft fault?
A new procedure has been implemented to ensure: – greater visibility of failure modes in order to improve repair process and parts delivery. For any suspected crankshaft/bearing failure, please contact your local Dealer Technical Support or FRED team for details of the enhanced customer handling procedure.
What kind of car has a crankshaft pulley?
In both cases the car was a 96-2000 Civic. Mine is the third one. On the first car, the engine had to be pulled from the vehicle to get the bolt out, lucky for the owner. In the second case, they had to remove the crankshaft, take it to the machine shop to get the broken bolt out.
What should I do if my crankshaft pulley comes off?
A long rod should be welded to the nut and the pulley is then held stationary as the main pulley bolt is tightened. No other way around it. If your woodruff keyway is damaged in the crankshaft – you need an excellent machinist to remake this – dont let him weld on the shaft, ask for him to make a proper and larger woodruff key
Can a camshaft pulley fall off while driving?
The camshaft pulley and bolt is the only thing that holds, the timing belt pulley in place and I was extremely lucky it didn’t fall off while I continued driving. At home, I inspected the pulley, there is a notch in the pulley that has taken a slight beating, and the splines on the pulley look worn.
Why did the pulley come off my Honda engine?
Secondly this gen Honda engine spins anticlockwise – if the bolt is loose it will work itself loose. The only way to tighten this bolt is to make a tool with a huge nut – something like 50 mm – it should perfectly engage the pulley hex cut that is cast into it.
