Jesus. It seems like the same behavior that caused this problem is at work again, with wanting to put the pulley back on. Apparently, people don't appreciate the forces, speeds, vibrations, and destructive potential about the crank.
So maybe the financial loss on this f-up is deserved, and the coming ones, as someone didn't learn.

Noticed how I said: For those who have done this kind of stuff before.
I never said I was going to just jump on it and do it for the fun of it.

I didn't know it was a sin to ask a question...sorry for that...I'll never do it again. I may as well just fork over $30K or whatever and buy a new engine from MB and avoid asking questions in the future.

And you'll get few who will either:
1. Admit to putting on a crank pulley on a crank snout they've already damaged, now with nothing to keep it keyed into place
2. Never have done such a thing, since they realized they ****ed up enough, and that would be obvious as something that would **** more up than fix.

That's harsh. Some peope may not know better but may be going by someone telling them "it's easy - you can save a few bucks and do it yourself" or something. You never know the whole story and he may just be trying to salvage what is unquestionably a bad situation. My opinion is that no one "deserves" to f-up, just like no one "deserves" to be born to an impoverished family in Africa and no one "deserves" to be born into millions. Sometimes s*** happens, man, and it looks like the owner and the tuner are working - very publicly, to their credit - to resolve the issue quickly and transparently.
Good on them.

The OP is a grown man and doesn't need another to request sugarcoating.
On top of that, it's fairly ludicrous for you to compare the owner of an E55, who damaged his crank, to impoverished families in Africa. That's quite silly. The tuner has nothing to do with this. They are covering their end to make sure no rumors start going around that their product was not made right and led to this.

Well, I know of a few that have had problems with the key on SRT-6's. I don't know the details but Waldig put a new key on the snout and as far as I know it was assembled and is running without issues. He's a curious man and an inventor of sorts. Perhaps you could send him a PM and he could give you some advise. Here's the link. http://www.crossfireforum.org/forum/...-survived.html

I've done everything from full engine builds to automatic tranny rebuild to turbo/supercharger kit builds by myself. I've also done crazy azz things that most people would look over their shoulders at me for doing them and they've worked great.
The big difference here is that I've never had such an expensive car before ( when new, not what it cost me used since my VW GTI cost me as much as my E55 did...even though the GTI was new ). I don't wish to sound like I know everything, but I just don't want people to shoot down ideas just because they are "different" or because it's not "by the book".
If everyone says "NO WAY" then I won't try it....but please give me good reasons not to try it. Don't just say "NO WAY" and not have a clue as to why you said it.

I wonder when the world started expecting that everything should be delivered, nice, sensitive, and even sugarcoated.

Anybody know what the keyway is used for other than timing mark alignment? I mean once the keyway is not there, the pulley should go all the way back then you should be able to torque it up, no?

I know what I'd be doing. I'd dig the key out, clean it up as much as possible and try it again. What can it hurt? The crank is already damaged. Not saying I'd rush this, but I'd make an attempt.
This was caused by the pulley and keyway not being aligned correctly. I don't care what anyone says, the pulley was spinning slower than the crank causing the scarring on the snout. If the key was lined up correctly, this would not have happened.

Eventually, wear between the surfaces will increase, the heat treatment and properties of both parts will change. Fractures can occur over time, then fail suddenly. Accessories won't run optimally, at the least.
I've seen a broken snout on a V8 BMW due to a faulty repair some time in the past, and it really was not nice, what happened to the front of this engine, radiator, core support, brackets, and accessories on the front of the engine.

Thats what I was thinking. Maybe your faulty wrench made it SEEM like it was on, when it was really still off the key way, and causing a wobble. you gased it, the crank spun, and the pulley did too, just not as fast, causing the scarring. Try Turbo 6's idea and buy a new tq wrench and a new key and put it back on. If theres already damage, why not see if it still runs properly with a slight problem.

The key is there not just alignment for the markings but as a "holding force" (lack of a better term) on the snout. It keeps any slop from ever happening (and also screwing up the crank snout.) Apparently torquing it alone isn't enough. That's also why it's such a PITA to remove a broken key. People even do ghetto jobs of welding a new woodruff and then they end up snapping off again and destroying the snout.
Sounds like your TQ wrench failed you. Sorry to hear it.

That's the way people learn about things. By asking and doing. Or not doing. Nothing wrong with it. Imagine all the blown motors the AMG engineers went through before getting it right. They asked themselves "dumb" questions and never said "no way." Nothing wrong with asking.

If the bolt was not torqued to spec and it started to loosen up, I guess the bolt could have come out enough to let the pulley get free from the keyway and cause the damage spinning and ultimately walk off completely...

It can break the end of the crank off, take part of the block and everything on the front with it. Not to mention sending a crank pulley flying through an engine compartment.
Eventually, wear between the surfaces will increase, the heat treatment and properties of both parts will change. Fractures can occur over time, then fail suddenly. Accessories won't run optimally, at the least.

The only time I've ever broken an engine...and it was a biggie. I even snapped the crank shaft...lol. This was my 2003 Infiniti G35.

I think it's the pressure the bolt puts on the pulley and crank that keeps it from spinning...not the key. Assuming my torque was too weak ( which apparently was the problem ) then the key would take the force and snap off. Make sense?
I just bolted on the pulley and slightly torqued it ( about 20ft-lbs on my screwed up wrench ) and it was very tight. It was so tight as a matter of fact that it took two pry bars for me to get it back off.

I saw the key inside the pulley keyway with my mirror ( it was the only way I could so it to begin with since it's way in there ) before I installed the bolt.
