This is really messed up (the thread or descrption whatever). You cannot push the damper too far back (towards its seated position). When you tighten the crank bolt with the damper in position, it is back as far as it can go, which is where it must be by design when engine runs. "Back" means flush against crank or back towards the rear of engine, right? So please clarify what you mean by "back." I think I'll just lurk.

I am not sure how the pressing of the clutch without the slave cylinder impacted the shifter. Well, the slave cylinder is toast - I will have to replace it before I sort out the shifter.

One step at a time.

can you post pictures of the damper??
From the info provided,
either there are parts missing on the front of the crank or the damper vulcanizing ring is indeed damaged.

Please report back your findings.
The vague postings will not give you the best return on the correct diagnosis

I put the harmonic balancer back on when I needed to turn the engine. I did not put the pulley on behind it. That is was cause the engine not to move clockwise. I looked at the HB, it looks fine now.

The harmonic dampener can be installed backwards. When that happens it will throw off the timing marks and the car will run like crap. AFAIK it will also rub if installed backwards. Please post pictures of your installation! We are trying to help here but your vague descriptions and lack of info is not helping.
Also the washer for the harmonic dampener should only go on one way. If installed backwards, you will get the correct torque, but it will come loose on its own and the pulley and dampener can fall off while driving. Others have had that exact occurance. WE NEED PICS!

Maybe I have not made this clear. Pulling the HB forward allowed me to turn the engine. All is right with the world except that somebody pressed the clutch in and I have to replace the slave cylinder.

I was clear about pulling the HB forward BUT this should not cause the engine to bind ..
UNLESS parts were left out of the assembly, , even if you did not install the AC pulley this alone would not cause the HB to bind the engine.

As has been previously stated posting pictures of your work will be a great way to evaluate your work ,
and possibly figure out if you have in fact assembled the front of the engine as it should be.
Other questions would be are the thrust washers installed and or are they installed correctly?
The things you have described make for concern as if the correct parts are not installed as they should be then the first crank of the engine could be catastrophic.
The clutch slave is easily replaced and hopefully will be bled to remove all of the air, that is a somewhat tricky to do

Mrmerlin hit the nail on the head. You CANNOT install the HB correctly and have it bind the engine up so it will not turn! The HB MUST be installed all the way aft against the crankshaft lip, and when done this way it will NEVER contact the engine block or the lower cover and it will not bind up the engine. If you have to pull the HB forward then how are you going to get the necessary torque on the bolt? Your doing something wrong.

For clarity - sounds like there's a reason it could bind.

Please shoot some photos and post them. There are some pretty well trained eyes around here...

If he -pulled the pulley away from the engine the how is his crank bolt torque?

Did you put the harmonic balancer on backwards, and leave off the AC pulley bracket? or did you bend the AC pulley bracket back? What did you pull? How do you know it looks fine?

Yeah well, this list is nothing if not zealously helpful

One last time then I give up. THERE IS NO PULLEY BEHIND THE HARMONIC BALANCER!!! There is a shaped washer that goes over the front and rear edge of the crank gear, but no pulley. All the pulleys go on the FRONT of the harmonic balancer. If things are installed correctly, even without the pulleys, nothing will prevent the engine from turning over by hand or with the starter!

Jim, I'm 99% sure he means the crankshaft timing belt gear.

He has multiple 928's, does his own work and has been on this list for 8 years. I figure he probably knows how to do it, and was just caught out by an unexpected binding that turned out to have a simple explanation

Anyway.. there is no more problem.

Same thing happened to me with the slave cylinder seal a few weeks ago.. only in my case the "someone" was me, forgetting the slave wasn't attached while doing something else under the dash. The slave cylinder promptly prolapsed and tore the rubber boot.

I had a complete new-in-box spare slave handy, but will buy just the seal kit to repair my old one, so I still have a spare for one of my other cars.
