Why does a crankshaft pulley go bad?
Another way a pulley can fail is during the fitting process there has been an interruption with the assembly press or the friction bearing has been incorrectly pressed in. This can occur during the making and installation of the part with the vehicle.
Can I drive without a 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.
Does crankshaft pulley affect timing?
When a crankshaft pulley fails (or the timing belt due to a badly maintained crankshaft pulley), the timing of the engine is completely thrown off. Even a rotation or movement of a few millimetres can start to cause problems in a system so precise.
What happens if the crankshaft pulley breaks?
When a crankshaft pulley fails (or the timing belt due to a badly maintained crankshaft pulley ), the timing of the engine is completely thrown off. Even a rotation or movement of a few millimetres can start to cause problems in a system so precise.
How much does it cost to fix a crankshaft pulley?
The average cost for a crankshaft repair runs between $50 and $105, with the labor generally being between $130 and $165. Although the crankshaft repair is for smaller issues, it definitely is a lot cheaper than a total crankshaft replacement.
How long does a crank pulley last?
How long does a crankshaft pulley last? They should last 70k ish, trouble is when you buy a new one its not a new one, its one that has been sitting on a shelf in a FGP warehouse for ten years.
Where is the crankshaft pulley located?
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.
Can a car run without a harmonic balancer?
And because the belts that go around the crankshaft pulley run all of the car’s accessories, without the harmonic balancer you’d have no air conditioning, no power steering, no alternator and no water pump. And without it, you can do damage to the crankshaft and the engine bearings. So you really do have to replace it.
What causes a harmonic balancer to go bad?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. If this happens, the crankshaft may develop cracks and ultimately fail.
Does the weight of a harmonic balancer matter?
No matter what anybody tells you, size does matter when it comes to the harmonic balancer you use on an engine. Putting an incorrectly-sized balancer on an engine will do more than just cause it to not reach its full performance potential … it will cause serious damage to the rotating assembly.
What happens if you drive with a bad harmonic balancer?
It’s not okay to drive with a bad harmonic balancer. 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.
