harmonic balancer removal

Well, I feel pretty dumb right about now being stuck on a balancer removal but whatever. Here's a link to show the basic idea.
http://shbox.com/1/pull_pulley.jpg

I've got the puller on and everything but the tip going into the socket is circular so it just spins inside. Am I supposed to have a square tip that fits securely into the socket, which would allow it rotate the socket, thus pulling the balancer away from the block?
 
looks like they are using the socket over the bolt head to hold the puller straight.
they are pulling the dampner off the hub. just tight the big bolt on the puller to remove the dampner
 
I am not sure why they are using that socket on the crank bolt. The removers I have used simply have a flat "hub" on them to push on the crank as you tighten the center bolt, thus pulling the balancer off the crank.

With that being said, you want the main screw to be able to spin, that is why they have ball/socket fitting on the crank side. Also, that crank bolt has to be off before the pulley can slide off, and it usually has a large washer which is stuck on with RTV.

he is pulling the balancer off, not the hub

OP, just tighten the center bolt, it will pop off
 
Alright, one of the arms had to be repositioned because the bolt was in the wrong hole (made one arm slightly longer than the other two). My new problem is that the harmonic balancer is rotating now that it's tight.
 
do you have any longer bolts to screw into one of the 3 holes? not to tighten down but just to keep it from spinning? I assume its spinning on the hub?
 
Tried the screwdriver and that does work. I just don't understand why this thing is so tough to get off. The three bolts are off and it didn't appear to be hung up at all on the crank hub. I mean I'm TORQING on this thing.

Def make sure the 3 threaded bolts are threaded in the same amount/lenght. If not it will bind and be hard to pull.

Do you have room to hit it with an Impact wrench?

If not you will have to try and brace the Balancer. Are there any holes you can brace it with a pry or screw driver while you try and spin the Puller?


EDIT, guess I type slow! LOL

I might be able to install one of the 3 bolts back into harmonic balancer and use a 3/8 drive to counter act the puller. Let me give that a try. Or a screwdriver...lol...thx dave.

all that will do is break the puller, or the damper


is the damper turning on the hub, or is the crank turning?

that wont work. the bolt cant be tight.
you could stick a screw driver in the hole though
 
The center bolt is bottoming out because it's not long enough. I have to adjust it or something to give me more threads. autozone didn't have the smaller version so I got stuck with the 5 ton 3 prong puller. It sets it out further from the balancer thus making it use more threads to reach the contact point.

ok, to be clear here, the picture is on a LT1 damper/hub
are you working on a LT1?

Yes, it's an lt1 and the screwdriver method is working best at this point. I was able to take a link out of each arm which shorten up the unit. Hopefully, this will do the trick.

use a deep socket then
 
Well, I have enough threads now but I don't wanna put too much torque on this thing and break it since it's a rental. Does it require this much tq to remove it or am I missing something here. All 3 bolts are off and everything is lined up. I had it off probably a year ago and the car has had less than 10 miles put on it since then so I can't imagine it rusted on there sitting in the garage.

if the three bolts are out, and you are sure the legs are only hooked on the damper, not behind the hub, keep tightening it
