Need some ideas on a vibration dampner that I can NOT get to budge!!
trying to tear down a 408 stroker for a friend, and I cannot get the vibration dampener on the crank to move. I tried my slide hammer, but I couldn't get a good attachment point to it with the crank pulley bolt holes. might have to fabricate a plate to pull it. hope not though, that's a lot of time and effort just to pull it off!
tried beating the outer ring with a hammer, but...I think the dampener is, well...dampening the hammer blows!
I'd like to add some heat to it, but A--I don't want to hurt the crank at all, and B--my torch hoses are dry rotted and cracked after just 4 years, despite being inside the whole time!!

I ASSuME that the dampner is junk and that's what you are beating on it wit ha hammer ??? You need a balancer puller , BOLTS to the hub of the dampner and pushes against the crank snout to pull it off .

When I spun the cam dowel off my 496, I found out that the damper that was hell to get on was even "heller" to get off!! We used a oxy/acet torch to gently warm the damper, but after numerous tries, it still wouldn't budge. So...off to the fridge for a bottle of "ice" water.....heated the damper up again and shoved the open bottle of water right onto the snout of the crank and gave it a good squeeze while we had a lot of tension on the puller. SNAP.....it cracked loose and off it come...albeit slowly but it came off. Next damper was honed a bit to get the fit right.

If you don't want to bring the heat, bring the ice! Get some of that freeze off, or cheaper, some dust off and invert the can while you spray the snout down. The white stuff coming out is liquid CFC (freon type stuff) and is some cold stuff. get as much on the snout as possible before your hand freezes to the can, and then use slide hammer or way better, a 3 bolt puller on the pulley bolt holes.
This sounds like a logical approach.

DUH! forgot about a pulley puller type tool with the big center threaded cone to pull with. probably because I don't have one!
I've never had a dampener give me this much trouble before!
and, on this motor, not much is going to be saved. his throttle body lost a threaded stud, which got sucked down the intake and beat the snot out of a head and piston. all he plans on keeping here are the camshaft, crankshaft, rods, and block. everything else is already stripped off the block. (I think now I understand why it was stripped down to the short block and he said 'hey, can you do the rest for me?!' HA!)
but again, I've never had a dampener give me this much trouble coming off!

Yep, borrow a puller from Autozone. Make sure you lubricate the threads on the puller to keep them from galling(especially if it is plated or you are using an impact wrench on it). Tighten the jack bolt in the center pretty tight and then smack the end of the bolt with a good size hammer. The damper should move. Just keep tightening and smacking the bolt everytime it gets loose and the damper will be off in no time.
In theory, there is no difference between theory and practice. In practice, there is.

Is there any other tool to remove a PRESSED ON dampner ? You can get one , called a steering wheel puller , albeit CCJ , at Vatozone for 20 bucks ....

You can also borrow the tools from AZ and O'Reillys. Maybe the brute force aspect is the military coming out in him.

And please use the install tool when putting on the new damper. Don't drive it on with the crank bolt if we see a thread asking on what size tap to use on a crank we know what you did 
Good point the first time I used a puller I didn't put the crank bolt back in when removing the washer that was preventing me from doing the job, and got the puller stuck in the crank. Turned out the block was cracked so no real damage, but leason learned.

Some of the nicer pullers come with a insert to put into the crank so this doesn't happened.

Good point a fair amount of aftermarket dampers can bee too tight or too losse depending on the brand. To tight is not a bad as you cam hone it slighty to get a better fit.

Yeah mine is a cheap one, but it had a button that goes on the end.
It was lost in the crank cuz I removed the washer, then didn't replace the bolt.  Ruined the crank but I still use the puller just need to remember to replace the nut after removing the big washer. We live we learn.

I got that topped. My friends dad who was a mechanic showed me how to remove a damper with the proper tool. So after using the PRY BAR i learned fast how not to pull a damper

I just used mine this morning to remove a flywheel from a 12 HP Briggs on a old riding mower. It's one of the first tools I ever bought for working on motors, I'm on my 3rd one. I ruined one trying to pull a welded on hub off a racing hemi. Got one at home and at work.

All the aftermarket Dampners I have purcahsed come wit ha sheet telling the end user that the dampner must be honed to size , this is why they are hard to install.
I guess because a damper must be firmly installed on the crank to absorb vibration.

Um... Just buy the tool... The good puller/installer is $100. You're hammering directly on the crank. You might as well be throwing the hammer from the slide hammer at the crank... It's not hard to bend the crank doing that. Especially a cast crank...
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

BETTER for the dampner to be a little tight ...than loose for the dampner to be effective. B U T ... as tight as some of these are(as some are describing it) .....  How the HELL did they get the dampner ON the crank in the first place ? ...... ...WITH a BFH ??

One thing to remember: any impact on the damper is transferred directly to the crank and thrust bearing.
If it's an engine you don't plan on rebuilding, don't hammer on (or off) the balancer.

Man that thing is going to be a pain in the ass to get off 
Maybe it was written in a language you couldn't read ... like CHINESE ...
If you have an aftermarket crank you can't count on them being in spec eiter definitley should have done some measuring.
I would have stopped and not went all the way on with it if it was fighting all the way on.

It seemed like a precision operation to me so I thought I'd leave it to a trained professional , plus he only charged me 20 bucks. I'M like you though and I try to do as mauch as possible myself , which is why I rarely finish anything I think.

It is a precision job, for sure. I have a dial bore gauge and a set of mics, No different than fitting bearings.
yup finishing stuff is the toughest unless you got a guy waiting to drive it, story of my life.

Consider that a gift. Mine hit the timing tab before it even touched the crank when I tried to fit it...before I found it didnt fit the crank.
Onto the "shelf of stOOpidity" it went!

X2. ATI recommends .008"-.0011 interference fit. I mic'd the crank and dropped the balancer off at the shop. As it turned out the balancer was within spec as delivered.
These are the instructions that came with a buddy's CCJ balancer:
question on the spec, .008 OR .0008 ??? .008 you would need to use a 100 ton PRESS to get that on ...

Maybe a smear of anti-seize next time?
