What happens when crankshaft pulley fails?

Spread the love

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 causes crankshaft pulley damage?

A crankshaft pulley is designed to last the lifetime of the engine. However due to wear and tear, high temperatures, exposure to coolant or engine oil (due to leaks), the rubber ring can become damaged. The rubber ring works as a vibration dampener which holds together the internal part to the outer part of the pulley.

Can you use a damaged crankshaft?

Crankshafts are manufactured from hardened steel. Once they are damaged, there is no approved repair available. Damaged crankshafts need to be replaced.

Can you drive with a wobbly crankshaft pulley?

Furthermore, the tension increases from driving all the components off the single pulley. If the crankshaft pulley starts to wobble, it will eventually throw off the belt. Not only that, but other components that depend on the pulley’s drive power will ultimately fail.

What is the function of crankshaft pulley?

A damper pulley, commonly known as a crankshaft pulley, is a pulley mounted at the front end of the crankshaft. It drives the acces- sory belts, which in turn drive the alternator, air conditioning compressor, power steering pump, water pump etc.

How do you diagnose a noisy pulley?

Pulley noise Bearing damage can often be detected by continuous grinding noises that increase as an engine’s rpm is increased. To locate the noise: turn off the engine, remove the belt, then hand spin all the pulleys to see if any are hard to turn, feel rough or rattle.

How do I know if my belt or pulley is squeaking?

How do you stop a pulley from squeaking?

Is a crankshaft worth fixing?

How do I know if my harmonic balancer needs replacing?

  1. Cracked, bulging or missing rubber.
  2. Harmonic balancer wobbles.
  3. Separatation between the hub and outer ring.
  4. Timing marks slipped. Timing error code or mis-fire.
  5. Excessive wear on main bearings.
  6. Oil pump failure.
  7. Broken crankshaft.
  8. Loosening or broken bolts.

What causes the harmonic balancer to wobble?

The wobble in the balancer can also be due to looseness or misalignment between the balancer’s inner hub and outer ring. The hub and ring should each be securely adhered to the thin rubber ring between them but sometimes they loosen. When this happens, the outer ring can shift and wobble.
