Default What is a crankshaft pulley? Is it the same as a Harmonic Balancer?

I also need one of those for my 1995 Honda Accord LX. And where can I find this part? First I need to know the difference between the names or if they are the same. I am highly confused by all of this because my ,mechanic told me I need the crankshaft pulley but the people at the parts place called it a HARMONIC BALANCER. PLEASE HELP ME

Yes, they are usually the same thing.

The harmonic balancer is often keyed to the crankshaft, and may have a pulley on it. This pulley often is used for the alternator and often the water pump also. As accessories are added (AC and power steering) sometimes additional pulleys are bolted on to it.

So they are not always the same thing. But if you just need the pulley, a parts store is not the best place to look. Often a salvage yard is better. So get out the phone book and call around.

But most places seem to be calling it a Harmonic balancer, you can get billet ones off of ebay and under drive pulley set ups too. Here is a used one:

A under drive pulley will free up a few horse power by the way. But it will take a different belt to fit.

Let me clarify the two previous answers. The Harmonic Balancer is the crank pulley on the Honda. A parts store will call it a harmonic balancer. It takes and hour to replace it.

Technically, that is only a crankshaft pulley on the Honda (it is all metal) but on other cars it is a harmonic balancer, with a core separated from the pulley by a rubber ring. The rubber dampens the vibrations from the crankshaft. Go with the flow - the parts place has a harmonic balancer and you need a crank pulley, make the deal. Same thing for your purposes, even though Honda calls it a crankshaft pulley (part 20 in the first source). Good thing you didn't ask for a pop while you were waiting and all they had was a soda machine.

Curiousteen is right - a wrecking yard pulley is okay, but a wrecking yard harmonic balancer is asking for trouble... that rubber ring has a high failure rate.
