A different motion profile was already successfully tested. There were some repairs still needed though and here it still sits.

It's because the current Yeti generates unacceptable forces for the structure if it is repaired, which means the structure has to be fortified OR you have to build an entirely new Yeti that is both impressive and light enough that it doesn't generate too much force. Both are expensive, and the latter doesn't yet have technology that will fully achieve the desired effect.

I'm still confused how the yeti is generating unacceptable forces for the structure. The yeti itself is not generating any forces, but the sled/arm it's on is. Are you saying that the arm itself is moving too much for the base? If so why not just create an animation profile that moves slower/uses less force?
I'm under the impression that you could do your B option of a whole new Yeti due to the fact that the Yeti's AA skeleton is basically already busted. It just makes more logical sense to me for a repair of the damaged arm, and run a reduced/slowed motion profile. @NormC chime in anytime more, you seem to know a thing or two I'd like to hear about.
I remember reading somewhere years ago (maybe even here) that there was a lighter Yeti that had been designed using carbon-fiber, and all that was needed was the funding and managerial desire to make it happen. And since the strobe light is still fully functional...

To be fair, Disney IT can’t even find “the Google”. But they have top men working on it.
The best insiders say Yeti is generating too strong a force for its own internal structure, i.e., its skeleton. The pistons, or the rods attached to them, are being torqued too much. That's why a revised movement profile that is less strenuous is a possibility... once certain repairs are made. Otherwise, they'd have to put in a brand new Yeti and also conform to tougher safety regulations for giant things above guests' heads that try to take a swipe at them.
But what do I know, I didn't sit in the meeting with Iger when this was being discussed.

The force the mechanism generates is reportedly more powerful than a 747 engine. This was explained in the TV special available on YouTube and discussed in the Yeti thread. This force has damaged the equipment. Exactly where is speculative but the top theory is the bearings or joints were not designed to handle that thrust repeatedly every day with every train that passes. The parts were replaced in the past but the stresses are too great and damage has occurred. When the main joint fails the stress gets applied to the next one which was never designed to handle that. It is a cascading issue.
A new profile has been programmed and tested but repairs need to be made nonetheless.
The various theories have been discussed in the never-ending Yeti thread.

Regardless of authenticity, it's a shame OP was bullied away. For a group that loves to dissect and converse on topics that pertain to a company that is inherently a family oriented brand, that's very sad. Ironic it's National Bullying Prevention Month. Forums like this should be all about inclusion, but too many view this as their personal space. To be fair, there are many comments on this thread that are constructive criticism and skepticism and those comments are completly important and needed for balance and gathering a fuller scope of topics discussed. But the bullying comments are just unnecessary and unfortunate, considering how rigid these forums are moderated sometimes. 2 cents.

I had been aware of everything both of you had written other than what I had underlined. I was just looking for more clarification on the new profile and what that would entail but I figure that's all you can add. Sorry for the confusion! When I was asking about my confusion on the forces being too great, I thought that it was being said that the structure was being harmed, which added to my confusion. Now that I see this is still not the case, all is well.

The structure of the Yeti was being harmed by its own forces. The structure of the coaster was not.

Oh. Didn’t see that he quit the thread. Nevermind then.

The biggest issue is that the Yeti, as currently designed, in A Mode generates enough constant force that it actually damages the overall structure over time via poor distribution of force through a central 4-story tower. You have to consider that the Yeti would typically run more than 12 hours a day, creating constant stress on the structure. At this point, there are so many things wrong due to lack of use and time, that the animatronic would need massive repairs to even get it in show shape again... but the design itself is flawed. If constant stress results in weakening of parts of the Everest structure, the whole thing would have to be shut down and major repairs would follow with huge costs and significant downtime (plus bad PR).
And to further clarify, that's because the central tower the Yeti is bolted to shares the same foundation with the rest of the structure.

This makes sense. Can I get some more concurrence on this? Do you have any background or insight into how the poor stress distribution was discovered? It can't have been something catastrophic like missing bolts or cracks in the tower or EE would have already been shut down. Additionally, I'm trying to find some sort of rough sketch or diagram on how the tower really is laid out with the distribution of the 3 layers; Mountain, Coaster, and Yeti. As it had been explained before each of these three layers were separated. But the idea of the Yeti sitting on something that shares a foundation with the coaster isn't a ridiculous proposition.
EDIT: I'm especially trying to figure out how the Yeti has been taken out in the third shift. Is there a door within the attraction built specifically to transport the Yeti in and out? I've been trying to find any record of such a thing but to no success.
There's a thread about the Yeti...

I'm not an expert on it, but I have friends who worked on the issue. I'm also related to a nuclear and mechanical engineer expert who explained the issues once I chatted about what friends and acquaintances had said. What I was told revealed the problem originally was that sensors kept being tripped at Everest early one, which then resulted in WDI being brought back in to run tests along with other departments. That's when they discovered what we call a "whoa-sh*t". It's fun when people talk about Disney code words, because the actual lingo we use in text messages is something along the lines of: "So I heard Yeti is being put in B Mode... what's up?" "It's a whoa-sh*t." "Oh God, what'd they do this time?"
And to really fix the Yeti as is, you gotta figure out a way to remove a 46 foot (I think that's right, it might be 45 and change) concrete tower, and then reinstall said 46 foot tower a new. Or you've got to fortify the existing structure, plus get a better designed Yeti on top of there.
