Should the crankshaft pulley move?

The camshaft and crankshaft pulleys are directly attached to the engine (camshaft and crankshaft) and will only rotate if the engine is running or manually rotating the engine by placing a socket and breaker bar to the crankshaft pulley bolt.

Is it normal for a harmonic balancer to wobble?

Noticeable Harmonic Balancer Wobble When the rubber isolator begins to deteriorate, the balancer usually begins to separate, creating a noticeable wobble when the engine is running.

How do you know when a crankshaft pulley is bad?

Bad Crankshaft Pulley/Harmonic Balancer Symptoms

1. 1) Engine Vibrations. The first symptom that will likely come up are engine vibrations.
2. 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator.
3. 3) Power Steering Pump Failure.
4. 4) Transmission Damage.
5. 5) Irregular Idle Engine Speed.

Can you get a harmonic balancer off without puller?

If you don’t have a puller or you don’t want to buy it, you can use a durable strap in pulling it. Simply insert the strap in the space and around to position the strap firmly around the center of the balancer. Then secure and pull the strap to remove the pulley.

What is a harmonic balancer pulley?

A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. The purpose of the harmonic balancer is to reduce engine vibration and in many cases, serve as a pulley for drive belts.

How much does it cost to replace a 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.

Is harmonic balancer the same as crankshaft pulley?

Is a crankshaft pulley and harmonic balancer the same thing? – Quora. No! They are two different things. The harmonic balancer slides onto the front of the crankshaft which has a keyway on it to keep it from slipping and a bolt and wide washer holds it in place.

Why is my harmonic balancer squealing?

if the squealing only occured when the car started it would be more likely a water pump bearing. If it only occurs when you enage the AC then it is a compressor issue. A harmonic balancer reduces vibration by allowing some slipage between the belts and the engine. It also absorbs woble.

How do you inspect a harmonic balancer?

Start your engine and check the harmonic balancer to see if it wobbles while the engine is running. Take a flashlight and shine it directly onto the balancer to see if it goes in and out while rotating. If it wobbles, the harmonic balancer is bad. Turn off the ignition.
