Frequently Asked Questions (FAQs)
1. How do I know if my harmonic balancer is bad?
You can identify a bad harmonic balancer by several signs. These include engine vibrations, noticeable wobbling of the harmonic balancer, unusual noises, an illuminated check engine light, and visible wear or damage. If you experience any of these symptoms, it may indicate a problem with your harmonic balancer.
2. How do you know if your crankshaft is damaged?
Crankshaft damage can be recognized by certain indicators. If you hear a clacking sound that matches the engine speed, it could be a sign of a defect in the connecting rod bearings. Additionally, if you hear a rumbling or grumbling noise from deep within the engine, it may be an indication of crankshaft bearing issues.
3. What causes crankshaft pulley to go bad?
The crankshaft pulley is designed to last the lifetime of the engine. However, wear and tear, high temperatures, exposure to coolant or engine oil due to leaks can damage the rubber ring of the pulley. The rubber ring acts as a vibration dampener and holds together the internal and outer parts of the pulley. When this rubber ring gets damaged, it can lead to a faulty crankshaft pulley.
4. How long does it take to replace a crankshaft pulley?
Typically, replacing a crankshaft pulley takes around 1 to 1.5 hours.
5. Can a car run with a bad harmonic balancer?
No, it is not recommended to drive a car with a bad harmonic balancer. The vibrations from the engine can become too much for the crankshaft to handle, potentially causing it to fail. This can result in the car not running and requiring expensive repairs.
6. What happens if crankshaft pulley is loose?
A loose crankshaft pulley can cause various symptoms such as a loss or change in vehicle performance, knocking or increased vibration from the engine bay, and even metallic tapping as engine parts slip out of sync. These issues are noticeable while idling or under load.
7. What happens if your crankshaft pulley is wobbly?
A wobbly crankshaft pulley can lead to drive belt edge damage. The misalignment caused by the pulley can result in damage to the edges of the drive belt, as well as potential harm to the idle rollers and non-metallic pulleys.
8. What happens if you drive with a bad crankshaft?
Driving with a bad crankshaft can lead to various issues. The engine may stall unexpectedly, which can be dangerous while driving. It may also result in the engine not starting at all after being shut off, or the engine running rough, misfiring, or hesitating.
9. What are the two most usual causes of failure of the crankshaft?
The most common causes of crankshaft failure are installation faults and wear. Softening of the bearing journals due to previous bearing damage or improper modification work, such as excessive regrinding, can also contribute to crankshaft damage.
