Harmonic Damper replacement
Hello all,
I'm getting ready to swap out the dancing pulley on my car and thought I had read somewhere on here that you can push the motor up a bit with a jack and the crank bolt and pulley without removing the power steering rack. Is it possible? I did a search and all I've been able to find was the cost when people took theirs to the dealer and the procedures in the TSB for the loose bolt.
Thanks,
Ryan

IDK how you get the pulley off that way, no room for a puller. Don't forget to index the pulley to the crank and weight the new pulley the same way as the old. The rotating assembly is not balanced all that great during assembly and they use the pulley and flywheel to get it into spec.

Got it done. Rack came out to do it. No weights to transfer from the old one.
No more chirping or smell of burning rubber from the engine any more.
Rex, I haven't ordered a pulley for anyone. I'll see how this one holds up. Don't need the 8 rib at this point and won't need it until the car is paid off.

There was an article that shows some pictures of the process.

The guys at A&A have alson done a great job at writing the steps for removing the power steering rack. You can find it in the install instructions on their website.
Good luck. It's a fun job.

I also did it the way of droping the front cradle a couple inches instead of pulling the steering rack.
Steering rack WOULD be simple IF the P/S lines wouldn´t run around the brake lines which is really soo stupid! Barely accessible and a major PITA.
Also a big b*tch was
1. to remove the center screw. I had one sat in the car, pushing the brake, tranny in 6th and a looong breaker bar to crack it open
2.to pull the pulley off the CS. It was stuck big time.. My puller almost gave in to it.
Also I still don´t understand how I should orientate the new damper on the crank regarding balancing. The old one was separated already and there are no weights, just holes in the outer ring.
Besides: How would I balance it with an e.g. Fluidampr? Not at all, right?

You would have had to mark the old pulleys orientation and line the new one up.

Ok, maybe I am just a little retarded here but I still don´t get it right:
The old balancer was apart already, meaning the outer ring with all the balancing holes was freely rotating resp. separated from the inner ring.
So marking the old pulley (inner ring) is meaningless or am I wrong?!
And the new pulley had AFAIR no marking which could have been used as an orientation compared to the old pulley..
And still: How is it when installing an aftermarket pulley? I guess they are balanced to zero by themselves so can´t do anything to "fine-balance" the crank assembly. Or am I wrong again?
Thanks for helping me out here...
