Hey Guys,

I need to replace my pulley or HB. I am not really sure. The pulley is wobbling and makes small chirps until the engine warms up. Which based on my research is a sign that is the issue. I have questions and concerns.

2006 Mustang V6 - 140K+ miles - never changed as far as I know.

1 - Is the crankshaft pulley and the HB together? Do you replace them and buy a new part as one?

2 - Ways to break the bolt without having to dismantle the front end.

3 - Do I need to replace the bolt or can I use the original with the new pulley?

4 - How do I secure the new pulley on? I assume since i need a tool to get it off more then tightening the bolt is needed to get it on.

5 - Any special steps for getting the key to line up (never done it before, just see in the pictures it has a space for it

6 - Any greasing/oils/etc. needed?

7 - tid-bits or suggestions?

Thanks guys.

Do you know if I can reuse the bolt?

Hey Guys,

I was going to buy a new crankshaft pulley/HB. When I got onto Rock Auto, there were several selections, but I have a concern. They all seems to have a different size gear (thickness and length) on each one. I was thinking the biggest one would be best but it has warranty of only 12 months while the smallest gear has a lifetime.

Here is the list:

Ultra-Power Brand: Cheapest, 12 month warranty, but the images don't look like there is much cuchioning for the HB.

ATP Brand: Close in cost, limited lifetime warranty, looks to be the best quality, but gear is the smallest.

Thanks for your opinions.

Since you are going to replace that, I would look for an Underdrive Pulley first. This will
free up a little more horsepower. They do not ADD it, they make more of it available to the
wheels by under-driving the accessory pulleys that are parasitic loss with HP. A kit will
come with a new belt, as a UDP will be a little smaller.

Like so:

You won't need to buy THEIR belt for that price though, that's rape...

Also, $15.99 on Amazon...

Not many options out there, and I could not find any for S197 on eBay....

Get a pair of Steeda underdrive pulleys and enjoy a 9hp boost in the process. They consist of a smaller crank pulley and a bigger water pump pulley, so you can reuse the stock drivebelt.
