harmonic balancer change help
My harmonic balancer is not good. so I can not do the proper timing.
because of this I buy new harmonic balancer. also read and watch a lot of video in .
how to change and install harmonic balancer
I find out that i need a special puller tool to get it out, also special installer tool to install
so I get the two tools. in order to be preper for the job.
now I have new harmonic balancer in box
new puller tool
and new install tool.
I went to the car just to find out there is a bar in from side to side in from of the harmonic balancer that prevent me to use tools also the rack amd pinon is in the way.
after that Iam thinking I will have to dismatel all the fromt of the car just to have good space to work.
so I was wondering. if any body have done this job. and what is the best way to do this.??????

If you search for replacing the opti on an LT-1 you will find a number of good write ups with this procedure.

I am in the process of this and it's so much easier than it looks! Unbolt balancer then like the other guy said beat on it from underneath.. have a good light so you know youre hitting the crank pulley not the hub! Hit one side then hit the direct opposite side to "work" it off. From start to off and out took me about 40min and mine was pretty seized on the hub.

A universal steering wheel puller (ava. anywhere) will pull it quick, sometimes you have to loosen the rack pressure line (on my 84 you do) or slighty raise the engine.
The installer is harder to find, don't use the bolt to pull it back on. You'll strip the snout.

I had to remove the harmonic balancer when changing the opti on my '95 recently. After taking the serpentine belt off I used a hammer wedged under the balancer while removing the three mounting bolts. I also put a dab of white marker paint to indicate where the balancer was positioned. When the bolts are removed, crawl under the car and use a strong piece of wood with a 2lb mallet. Position the wood on the back of the balancer, alternating from side to side, and beat the damn thing off with the mallet. It takes awhile but it will eventually come off. You can also spray the inner part of the balancer with PB Blaster to loosen the rust between balancer and crank hub.

I just changed mine.
Before removing the belt, loosen the bolts on the lower crank pulley.
There are 3 bolts holding the pulley to the balancer and the center bolt holding the balancer to the crank.
I loosened the 4 sway bar mounting bolts to drop the bar down a bit and disconnected the line on the top of the rack.
Doesn't take long and makes the job much easier.
I wouldn't hit anything with a hammer. That can't be good on the crankshaft. You already have the correct tools to do it right.

I think the sway bar is not that big of a problem but the bar on top going from side to site. is right in front of the lower pulley....

Having a hard time finding my pics, but I used the puller you pictured and the threaded bolt just fit between the rack and the metal fluid line coming out of the rack. I will look again after work, time to eat.

If the motor runs I suggest leaving the belt on and backing out the three bolts two complete turns. Then run the motor for a few seconds. Remove the belt and the three bolts and see if the hub pulley/balance slides right off.

You guys need to know that lt1 engines have a different type of set up(2 piece) then the older engines. The OP has a 86.
If you loosen the p/s line you'll loose some fluid, thats all, refill when your done.
