Okay i first posted this on a local site but, i believe there running outta ideas. So here it is i went to pull my Harmonic balancer off the other day.
*First off the pulley was stuck then we got that off.
*So we moved to the Hub
Tried and tried with the pulley. '

Then the worst happened. On the hub you have 3 flanges.
ONE F*CKIN BROKE. My car has been in a wreck so i just wounder if the crash cracked it. But any how. I can't get the hub off. I have found one localley.
So that isn't the prob. THE PROB IS gettin it off.

day 2 I tried to use the pulley and pry aginst it. Did not work needless to say.

Worked on it for 3 hours today. Tried to pull it off with the balacer puller but it just pulled the opposite direction of the broke flange.

Went and got a 2 Jaw puller from a buddy who should be ASE Certified but can't pass the test. he helped me today. The two Jaw just could not get latched. Or get a good bite. Came up with all kinds of crazy ideas to keep the Jaws together. Tie strapped it and a few other none worked tho.

So tommarrow i'm gonn atalk to a local shop and see what they have to say. I am all out of ideas.

I found it easiest to pull the hub with the balancer still bolted onto it.

 

Heat it up with a propane torch and beat on it or try to get the puller on it.

 

DO NOT do that propane torch idea.....metal expands when heated as we all know, which means the crank snout will end up most likely being just as tight, you will risk deforming other parts or possibly melting timing cover seals....

anyway....go to advanced auto or autozone, whatever is there where you live and get a 3-toed pulley puller!!!!

even with only 2 good flanges, i would assume you could get the hub off...the only reason it is being so hard is because it is such a ridiculously tight fit on the crank snout, thats all

so dont do anything ridiculous and just approach this calmly...oh and make sure the crank bolt is out!! i believe it is a 7/16" fine threaded grade 8 bolt inside housed inside of the hub

 

You need to find someone who has a kent-moore J-39046. This LT1 crankshaft hub remover and installer. If that does not take it off, nothing will. I would say buy one, but they are kind of pricey (249.00). Best birthday present ever.

 

Again, my 3-toed pulley puller was $20, your decision...it got the hub off in about 2 minutes of wrenchtime...$249 is bit steep

 

I suspect that you broke the hub by improperly trying to remove it. Did you use something down the crank bolt hole to push against with your balancer puller? If not, that is where you are going wrong and you will never get it off if you you are still doing it the same way.

If you did it correctly, disregard paragraph above.

 

If it was mine I would heat the hub up cherry red with a oxcy acetoelene sp? torch and pull it off using your puller. The propane torch idea was good but that would not get it hot enough. If it burns up your seal....just replace it...who cares.

 

Can you email me at shoebox@swbell.net ? I want to ask you a question. You don't have your email posted in your profile.

 

Use a pully puller that you rent for free from auto zone (make sure the bolts they give you arent stripped


If you must, use a MAP gas torch and light her up real quick, propane is too weak and a lot of people can't afford an acetyline torch

If you can get the puller for free then you might not even have to mess with the torch, You actually tried getting that thing off without the puller tool???!!

cool?

 

I used a 3 claw rented from Autozone and a hacked off piece of all thread to push against. The hub came right off this way.

 

Ok for one thing i am 18 years old and can fulley assemble a motor. That includes the bottom end i have did to 3. and they and are all still running.

*I also know how to use a harmonic Balancer pulley correctly. to clear this up. Let me repeat my car has been in a wreck was hit in the front end. So i don't know if that had an effect on it or not, put i think the impact may have weakend the metal. Cause i had the pulley perfectlt stright. Like i have said i have pullied numerous balancers.

And My own car is the ownly one giving me trouble. We don't have a autooZone yet. (In the process of being built) But we have a Napa and Advance so i'll just go buy a 3 Jaw puller and see if it will come off that way.

But thanx for your all help tho i appriate it. I'll update it later this evening.

I ended up having to cut mine off with a oxy torch. Cut it down three sides of the pulley and it finally made a loud POP and it fell right off. It was seized really badly, and I broke about 80 dollars worth of pullers that I was having to buy in the process. I was taking it off correctly also, as I had done this before. If they are really stuck, the ear will break off if you put too much pressure on it. My ears were all bent inwards when I got done trying to pull it with a puller.

 

No need to get defensive when someone is trying to help. Lots of people that have pulled balancers before have made a mistake with the LT1, because it is different than an SBC. Maybe you have pulled lots of LT1 balancers, maybe not (you did not say). You cannot take it off exactly the same way. Your problem fit the mold exactly like someone who did not understand the solid nature of the center of the LT1 hub. Sorry that you think a constructive suggestion that has helped many people is insulting to you.

Weld the ear back on and try pulling it again.

 

I didn't see it mentioned yet but did you notice that looking down into the hub it necks down to just a half inch so you cannot get the jackscrew on your puller to go all the way down to the crank snout itself? On LT1's I usually leave the crank bolt in there but backed out several turns and run the end of the balancer puller onto that. When it pulls out a little bit then I back out the crank bolt some more and go back at it.

No need to feel bad about it as most of us have been there before.
