Can a harmonic balancer be used on a crankshaft pulley?
Can a harmonic balancer be used on a crankshaft pulley?
Pull the old crankshaft pulley out. Now it is time to install the new harmonic balancer. You will need to hold the crank pulley using the harmonic balancer tool. Next use a breaker bar and a cheater pipe/extension to loosen the bolt. The last step is to reinstall the serpentine belt.
What are the symptoms of a bad harmonic balancer?
This is a list of common symptoms of a bad harmonic balancer on a Mercedes-Benz. Crankshaft pulley excessive movement. Pulley outer ring separating from the center. Crack on the harmonic balancer pulley rubber. Noise from engine. Crankshaft pulley wobbles.
When did Mercedes Benz replace harmonic balancer pulley?
A service bulletin was issued in April of 2005. Several Mercedes model years including 1998-2001 Mercedes Benz MB C CLK E ML R S SLK were identified to have a defective harmonic balancer pulley. The dealers inspected the cars and replaced the harmonic balancer if defective.
How much does it cost to replace a harmonic balancer?
If you change the harmonic balancer yourself it will typically cost you around $150. You will spend around $50 for the harmonic balancer tool and around $100 for the crank pulley itself. You have a couple of options when it comes to replacing the harmonic balancer.
How to remove harmonic balancer from crankshaft?
When you have the tools above, you can start removing the device. 1): Gently pull out the serpentine belt to gain access to the harmonic balancer. 2): Second, remove the bolt at the center with a wrench or pliers. The center bolt supports the dampener.
Why is the crankshaft pulley and harmonic balancer important?
You may think that the crankshaft pulley is not as important as other parts of your car’s engine, but actually, it is vital to the proper operation of your vehicle. The crankshaft pulley comes with a harmonic balancer. Just from the name, the crankshaft Pulley/harmonic Balancer is a mediator between pistons and crankshaft.
What happens if you have a bad harmonic balancer?
If a malfunctioning harmonic balancer is installed, too much stress is applied to the crankshaft. If this continues, your auto will not start due to a cracked crankshaft. As mentioned in the introduction, the elements absorb and resist the vibrations’ acceleration. Hence, the harmonic balancer is an integral part of your car’s engine.
What to do if your crankshaft pulley is bad?
When you have the tools above, you can start removing the device. 1): Gently pull out the serpentine belt to gain access to the harmonic balancer. 2): Second, remove the bolt at the center with a wrench or pliers. The center bolt supports the dampener. It’s usually very tight. 3): Remove the equipped pulley.
What happens when the harmonic balancer goes bad?
The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.
What are the torque specs for a harmonic balancer?

What does a bad crankshaft pulley do?
Home » Blog » Mechanics » Bad Crankshaft Pulley/Harmonic Balancer Symptoms & How to Remove It The crankshaft pulley/harmonic balancer is a mechanical system that distributes power to other systems of a vehicle. This component is connected to the crankshaft, which is another part that transforms linear motion from the pistons to rotational movement.
What causes the timing marks on a harmonic balancer to shift?
Misaligned timing marks. The harmonic balancers found on many vehicles are constructed as two pieces of metal with a rubber layer in between to dampen the vibrations. If the layers separate or slip, the timing marks, which are usually stamped into the front of the pulley, can shift and thus throw off the placement of the timing marks.
