Installed one
Heated it up for a bit 10-15 mins
Then out over the balancer and used a hammer to tap in. Went in but did get bent a bit at the top (should have taken pic)
Is it ok for the top to get bent a bit ?
Installed it but work up this morning thinking about it
 
The top part that you are pounding on needs to go through the seal. So make sure it’s smooth and lube it up before installing. When installed the seal is riding towards the middle of the sleeve and that should have stayed in good shape.

Thank you for the insight very very helpful so I’m going to put a picture to give you an idea of what got damaged just double check

thanks first time doing this wanna get it right at least

The lip mostly got damaged going in with the hammer but the neck went in smooth as no damage or bend there
 
The ideal way to do them is to place the sleeve in an oven at about 250 degrees for about 30 minutes. At the same time the dampener could have been placed in a freezer for about an hour. With that being done there would have probably been no pounding needed.

Wow freeze and heat not needed for a harmonic balancer at all. Sad to say this but if you have a groove where the seal rides replace the harmonic,

So you never parked a car outside in freezing weather, I didn’t say the heat the balancer just the sleeve so it didn’t need pounded on.

Grew up in the cold weather still dont know what you ask the repair sleeves for these are not a good way,
 
I was a industrial Millwright for 46 years and repair sleeves are used in hydraulics, pneumatics, shafting and all wear surfaces. Heating and freezing is used to expand and shrink materials and it’s a economical way of repairing usable parts that have flaws. The sleeve was a good recommendation and I’m sure the OP appreciated the savings. There is also a product called Belzona that is a two part aerospace machinable product used in industry every day. I stand by my recommendation 110% because I have done it hundreds of times and have saved hundreds of thousands of dollars.
 
You do NOT need to heat the sleeve to install. The sleeve is about 0.010" thick, and depending on how you heat it, you can damage it. If you are worried about the installation, you can purchase an installation tool which is made of nylon to protect the sleeve. The other thing is NOT to use a metal hammer to install. All you need is a plastic hammer, and lightly tap in on. dress down any damage down with a file, and carefully install. The main thing is to drive it on as straight as possible as any out of alignment will pooch the sleeve out. If it does get pooched, you can carefully use the plastic hammer to flatten it out the best you can.

If it’s heated in a uniform even way it won’t hurt the sleeve at all which is why I recommended an oven, we used electromagnetic heaters. If it’s done right it shouldn’t need taped on, it should drop onto the shaft as long as the shaft has been dressed and there are no burrs. Please keep in mind that the temperatures I am talking about are NOT beyond normal operating temperatures but not at the same time for each part.

I agree with Red63440, slow even heating of the sleeve, 30 min and the damper in the freezer for 1-2 hours. The sleeve will drop right on, no tapping or force needed.

The issue is the lip it hot banged when o used a piece of wood to get it in and tapped that with a hammer

so should I just toss this abd get another harmonic ? Or proceed ?

Easy fix is not always the best fix.
