Any feedback on the Jegs Universal remover/installer kit? http://www.jegs.com/i/JEGS-Performance-Products/555/W89711/10002/-1I bought one and it seems pretty nice, but I have not had to pull a really stuck damper with it? As Shoozy said, soak it, put tension on it, tap it a bit, and let it sit overnight. Then repeat. If your going to trash the damper, hit it with some good heat from a torch. On the aftermarket stuff (crank and/or damper), check the press fit of the damper to crank. According to my machine shop, it is fairly common to have to hone the damper a bit so it is not too tight? My ATI damper was honed at the machine shop to fit correctly. ATI says 0.002" for the aluminum hub units, and 0.0007" for steel. The Romac sheet on-line just notes 0.0005"? I have the same puller under the proform brand. It works great and is a great installer as well.

This is what happens when someone fails to hone the new damper to fit the crank. If you're lucky, you won't gall up the crank snout and the damper's hub. Seen it many times when someone crams a new ATI or Fluidamper onto a crank w/o honing them to fit first.

So glad I read this. I tried to install a new stock damper on my 383. Put the old one back on. Guess i'll get some new honing stones and take my time getting a proper fit. Anti-seize also a very good idea. Thanx, and a to you all.
I have mechanical Aptitude. I can screw up anything.

We live and learn. Crank snout has been machined and looks OK, has a few dimples but will be fine, will be fitting an old ATI that I have, will do a fine film of anti seize and locktite the bolt. Cheers

44 years of building engines and I’ve never used lock-tite on a mopar damper bolt.

These aftermarket balancers are often too tight. I think the manufacturers think if it's too loose you will return it but if it's too tight they can just tell you to hone it. If it's that tight then it needs to be honed. You can't properly hone it with a regular hone because it has a keyway. And even if you could you don't have accurate enough measuring equipment for this job. (We are dealing in tenths here.) Most automotive machine shops have a Sunnen rod hone and a keyway mandrel. The B/RB spec is .0005"-.0015" with .001" preferred. Nothings easy any more.

ATI instructions say to NOT to hone their hubs I've used a bunch of their dampeners without honing them, they all went on fine I haven't remove all of them after using them but I did and do use antisieze on all new dampeners regardless of brand I believe the ATI instructions to not hone are for the aluminum hubs. They are supposed to have 0.002" press fit from what I was reading. Also agree w/ what Rickseeman said above too. I have never had an ATI or Fluidamper that did not need honing to go on correctly.
