What is a crankshaft damper 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. The simple pulley has a damping effect on crankshaft stresses.
Can a sheet metal pulley be retrofitted to a damper pulley?
This damper pulley can be retrofit to earlier engines like the MGA. Aside from the weight and risk of rubber failure, the damper pulley is also thicker that the sheet metal pulley (same diameter). This may interfere a bit with the steering rack during installation of the engine in the car.
How does an isolator pulley work on a crankshaft?
A crankshaft isolator rubber effectively eliminates these vibrations directly at source. At the same time, the torsional vibration damper in the isolator pulley reduces torsional vibrations within the crankshaft. The vulcanized rubber spring provides an elastic connection to the belt drive.
What does a harmonic damper do to a crankshaft?
Yes, the Crank Pulley with Damper is often called “Harmonic Balancer”, but it doesn’t really do any balancing (like adjusting wheel weights). It does damp out some harmonic vibration in the crankshaft, but not the kind of vibration you could ever feel. With each power stroke the crankshaft speeds up slightly.
How does a torsional vibration damper in an isolator pulley work?
At the same time, the torsional vibration damper in the isolator pulley reduces torsional vibrations within the crankshaft. The vulcanized rubber spring provides an elastic connection to the belt drive. A dry bearing enables relative movement of the pulley. Torsional Vibration Dampers absorb rotational vibrations in internal combustion engines.

Where is the pulley located on a crankshaft?
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. The pulley is attached to the balancer using bolts that can loosen over time.
What happens when the crankshaft pulley goes bad?
But if the balancer starts to go bad for any reason, the vibrations won’t be absorbed anymore. This will cause the engine to shake profusely the faster you go. 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator. So naturally, if the crankshaft pulley goes bad, then you can expect the alternator to stop working.
