I have to check into the installation tool.

Can I use a generic install tool like this one, or do I need a specialized tool for this?    https://www.autozone.com/p/oemtools-engine-harmonic-balancer-kit-57144/391373?searchText=harmonic+balancer+puller

As long as a 9/16-18 adapter is included with the set, most of those damper installer tools will work with the car and pickup Ford Y dampers.  Due to the recessed depth of the Thunderbird dampers, I had to machine a spacer to work in conjunction with the installer tool to facilitate the damper installing process.  Here’s a picture of my Thunderbird damper installation tool.

I tried the correct tool from Hills Thunderbird.   I was using the crank shaft bolt for a contact point for the tool to press against.  The end of the tool keeps walking off the crank bolt, at one point the tool bent (see picture below).   I was able to straighten it with heat.   Now I inserted the tool directly into the crank, which is what Hill's recommended.  I ground off the treads on the end of the tool to keep them from galling the threads on the crank.

I am using a breaker bar and socket to turn the tool.   The pulley doesn't want to budge.  I am going to try an impact wrench, maybe the jolts will help it break free????    To do this I have to move the AC condenser for the impact wrench to fit. 
 Any problem using the impact wrench?
 

Ross, I'm sorry that you're having difficulty removing the dampener; mine was easy. Although it's been a while, I only remember using an impact wrench to remove the bolt. However, I've experienced difficulty on other things that also should have been easy. I think we all have. 

Merry Christmas.

You also have to consider the quality of the tool. 

Most likely off-shore junk sold for big bucks.

An impact wrench typically helps with the damper removal process.  Here are pictures of both a homemade damper removal tool which requires a spacer to help with using the shorter bolt and also the factory damper removal tool for the Thunderbird dampers.

When a part of the tool bends out of shape the tool cannot be removed from the pulley and must be cut out (I'm still working on that).   I ordered a new tool It looks like this, the end swivels, last one did not have this feature.   If this one doesn't work should I try heat????

I could not remember what my puller looks like, so I just retrieved it from my toolbox. It's the same as the TL7 tool that Ross posted. Neither the tool nor my dampener was damaged during removal. I don't know where the tool was made, but I paid about $40 for it.

I straightened  it as best I could.   I had to heat it up a few times.   The shaft bent again (maybe the heat weakened the metal?)  that's why I ordered the tool from Casco.   With the shaft bent the puller cannot be removed from the pulley......   I have to figure out a way to cut it without any collateral damage.    New Tool should be here tomorrow
