help with harmonic balancer
im trying to swap out the harmonic balancer for a 8 rib setup but the stock one wont budge. im literally out of ideas, i tried heating it up, tapping it with a sledge hammer( probably not a good idea), spraying wd40, but it wont budge. i bent 2 3 jaw pullers, and i went to auto zone and i found a better 3 jaw puller, but it still isnt budging, i even used my impact gun. i was hoping to finish this install sometime this week, but now im not sure. oh, and to make matters worse i broke the metal piece in the power steering pulley trying to take it off, so tomorrow im going to take it to a machine shop and have them take the ps pulley off the pump. everything was going so smooth until it came time to remove the harmonic balancer. does any one have any ideas. thanks in advance.
here is the tool i was using, with a socket at the end, but i ended up breaking the socket
and here is my nemesis
and the power steering pulley

no im not the original owner, but however i did swap a cam in there almost 2 years ago and i did not pin it. one of the reasons it has chunks missing is cause i got a bigger 3 jaw puller and put the jaws on the outer pulley to try it that way, but it ended up breaking some pieces off as you can see in the picture. its funny, when i did the cam, that thing came out so easy with the puller. btw, i only was able to torque it down to around 210ft lb when i originally installed it.

I'd refrain from using a sledgehammer......that can only make things worse.
If you used a jaw puller on the PS pulley, that's why it broke. There is a special puller for that pulley......relatively inexpensive too.

All I can say is use a TORCH and heat the "HUB" of that balancer till it gets about 200 deg. I heated mine and I was able to use a 3/8 drive ratchet to get it off. Regardless if it pinned or not, it should come off. Unless someone has drilled thru the damper and crank and inserted a long pin thru BOTH, it should come off and heat will really help. Get cooking!

You certainly won't get anywhere pulling it from the outer diameter. If you are going to use an impact, then you should use impact sockets.....as you can see....regular sockets will crack....even the good ones.

i actually bought the special tool that goes around the metal ring for the power steering pulley but it literally shattered it as you can see

YES!! Jack it up! Remove the radiator/fan assy. You DO NOT need to fully remove the rack. You can disconnect it, and unbolt it,, slide it part way out and push the passengers end foward.
That will allow you you to do all you need to do. Been there DONE that;

Hey thanks for the input. What is the big wrench for? Did you have to deal with balancing the new HB?

At the time of removal, I had a severe oil leak from the main front seal. I didnt have any way to hold the old damper from turning durng removal. The pipe wrench worked excellent!!!
I found a nice used strap wrench that works OUTSTANDING for removal/reinatall.
I can remove and install the damper my self.
Note the home made install tool!!!!
You will need something like that also.BC

IF,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, you install an OEM damper,,,, and have a manual trans,,,,, your supppse to mark the position of the old damper and transfer the OFFSET WEIGHTS on the old damper to the new damper.
I installed a POWERBOND Damper (has NO provisions for weights) and I had ZERO issues.
Purchase and read the service manual...
