How do I know if my crankshaft pulley is bad?
Bad Crankshaft Pulley/Harmonic Balancer Symptoms
- 1) Engine Vibrations. The first symptom that will likely come up are engine vibrations.
- 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator.
- 3) Power Steering Pump Failure.
- 4) Transmission Damage.
- 5) Irregular Idle Engine Speed.
What happens if 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.
When should I replace crankshaft pulley?
Signs that your crankshaft harmonic balancer needs to be replaced include: The engine is loud and you feel vibrations coming from your engine. The pulley belt may slip causing your vehicle to backfire or misfire. The vehicle’s ignition timing will be off.
Is crankshaft pulley and harmonic balancer the same thing?
But, they are technically not the same thing. The pulley is bolted onto the harmonic balancer. This pulley’s purpose to provide a place for the drive belts to ride and in turn they spin around all the components that have pulleys. The harmonic balancer’s purpose to counter act the crankshaft’s imbalance and vibration.
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. Other pulleys could get distorted if a fastener is missing and in such condition could damage the drive belt riding on the pulley.
What does a bad pulley bearing sound like?
If your idler pulley is worn and the grooves do not hold the belt firmly, you will hear a squeaking noise from the engine. When the bearings are worn, they make a rattling noise. At this point you should stop your vehicle and diagnose the problem.
What causes crankshaft pulley wobble?
The pulley is pressed on to the hub between a thick rubber dampener. Once it gets bent it’s going to wobble. It may have been in an accident or maybe some debris got caught in there.
What are the symptoms of a broken crankshaft?
Symptoms of a Bad Crankshaft Position Sensor
- Your “Check Engine” Light is Blinking.
- It’s Difficult to Get Your Vehicle to Start.
- Your Vehicle is Stalling and/or Backfiring.
- The Engine is Making Your Vehicle Vibrate.
Should the crankshaft pulley spin freely?
The air conditioning compressor has a clutch on it that should spin freely as well but it will not be rotating the internals of the compressor. That you cannot rotate either cam or crankshaft pulleys by hand is completely normal. If you were able to rotate them bare handed, THEN you would have a problem.
What does a bad harmonic balancer look like?
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.
What kind of noise does a bad harmonic balancer make?
A faulty balancer can result in a knocking, rattling, or squeaking sound that corresponds with engine speed. In some cases, the noise is bad enough to be mistaken for an internal engine problem.
Can you drive 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.
How much does it cost to replace the harmonic balancer?
Cost of Harmonic Balancer Replacement
On average for most vehicles, it can cost about $200 to replace a harmonic balancer. The cost of replacing the harmonic balancer varies mainly due to the type and model of the vehicle and the type and brand of parts used.
What makes a harmonic balancer 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.
Can a harmonic balancer leak oil?
If the balancer is worn where the seal rides, it can cause an oil leak.
