What happens if your 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 replace a pulley crankshaft?
The crankshaft pulley replacement cost is between $350 and $400, depending on the car model and labor costs. You could spend $200 to $240 for a new crankshaft pulley, plus about $150 for labor. If you purchase an aftermarket crankshaft pulley, you could save yourself a little money.
What causes crankshaft pulley failure?
All components come with a recommended torque, this should be checked before the parts are tightened. Similarly, if the belt tension is too strong or the auxiliary equipment has failed the pulley will also fail. The cause is linked to the coupling having made contact with the flywheel rim.
Can a crank pulley be repaired?
With the proper tools, removing and replacing a crankshaft pulley is a straightforward process that shouldn’t take more than an hour or two if you’ve had some experience working on a car.
Can you drive without crankshaft pulley?
If it was the crank pulley, such could fall off (eventually) and if it does cause a fair amount of damage if it happens while the engine is running. 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.
Can a bad pulley cause no start?
Can A Bad Pulley Cause Car Not To Start? As your alternator may not properly charge from the failing idler pulley, then the battery would get dead, which in turn could lead to starting your engine off.
How long does it take to replace a crankshaft pulley?
between 1 to 1.5 hours
A typical crankshaft pulley replacement usually takes between 1 to 1.5 hours.
How is a crankshaft pulley removed?
Many people try to remove it using a puller, but this often leads to damage to the pulley or the crankcase. The easiest way to remove a crankshaft pulley without a puller is by using a strap wrench. The more secure way is to use a pipe wrench in combination with other tools, like using a breaker or cheater bar.
How much does it cost to replace a pulley?
The total price to replace an idler pulley can range between $80 and $200. This range includes the cost of the new part as well as the cost of labor. Typically, the auto parts cost ranges from $40 to $90, and the labor costs about $40 to $110. Moreover, the cost also depends on the vehicle model and parts needed.
How much does it cost to fix an engine pulley?

How do you fix a broken crankshaft?
All you got to do is cut off the end of the crankshaft. Nice and flush and try to get a center punch mark as close to the center of the crankshaft as you can.
What would cause a harmonic balancer to break?
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.
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.
Can a faulty harmonic balancer cause a crankshaft to break?
What Happens When a Harmonic Balancer Fails. Although the harmonic balancer may seem simple enough, if it fails, it can cause major problems. Without the balancer dampening unwanted crankshaft vibrations, engine failures, such as worn rod bearings and a broken crankshaft, may result.
Can a car run without a harmonic balancer?
The harmonic balancer is essentially part of the crankshaft pulley. 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.
Can you repair a harmonic balancer?
The good news is, the harmonic balancer can easily be repaired with a kit that usually retails for under $10.
Is a harmonic balancer necessary?
A harmonic balancer sounds like a crucial part on a spaceship in some pulpy 1950s sci-fi story, or something you need so you can play music with hobos when you’re ridin’ the rails. However, it’s actually an important part on your engine that helps your crankshaft last as long as possible.
