The Clamshell Bent Today.
 

While trying to lower the top earlier this week, as I've done a hundred times before with no drama, apparently the right side's motor mechanism failed in some manner.

But the left side kept trying to raise the clamshell, with the end result shown below:

OK, an update.

The drive mechanism has been repaired, and the top / clamshell now go up and down as they should. (Side note: Failure was due to a broken cable end which disabled the drive on the passenger side).

Now my attention shifts to getting both ends of the clamshell to sit flush to the rest of the car.

Driver's side:

Compared to the passenger's side, which is pretty close:

In addition, the front "point" of the clamshell is also off on the driver's side. Here's the correct-looking passenger side:

While the driver's side looks to be shifted:

The situation now is that, looking at the underside of the clamshell and the linkage between the motors and the bracketry, I see no indication of adjustment capability. Certainly there must be some means to fine-tweak the fit of the clamshell, but I see nothing.

Any hints? (A Search of this Forum for this info came up empty - can I be the first person to have ever encountered this?)

Thanks - DM

Minute 10:30 onward they give you some hints:

This is indeed a very good video.

If there is a permanent twist in the clamshell
the arms that raise it or the mounting points to the body.
You will probably never adjust the twist out.
I would take everything apart and make sure there is no twist present in any of the parts.
Once your sure there are no twists in anything then you have a good baseline to start with.

Update, with thanks for the earlier posts and recommendations (and yes, the video in Post no. 3 was very helpful!):

While removing the clamshell, confirming that yes, indeed, it has a twist in it, I found this item in the driver's side clamshell mechanism. Part number shown. There wasn't a similar one of these on the passenger's side.

Anyone recognize it and know what it (they?) is supposed to do?

Grateful for any clues!

Google revealed it in .0087656 seconds. ;)


***** = sierra madre collection (with no spaces).

I just revealed the first Google result. Personally I purchase my parts from Pelican, but the Sierra site describes what the part is for.

Pelican... if you can hide the name of your competitors, surely you can provide a description for your parts. Up your game.

I found the same part on Auto Atlanta's website with a diagram showing where the part goes. I agree with Starter986 totally.

Thanks, guys, for the reply. And I can now see what happened.

Before I posted the pictures, I too did a web search on the part number via my (non-Google) search engine. The difference was that I broke the 9 digit part number into 3 groups of 3 digits, separated by the pair of periods, exactly as shown on the part and on the paper as you can see. This search came back empty. But then, based on your reply, I went back and repeated the search using this same search engine, now as a single 9 digit number w/o periods. And yup, lots of hits! So, Lesson Learned, with my thanks to you all for the insight.

In any case, the various parts diagrams which are contained on some of these pages clearly show a pair of these parts are to be used. But in my case, there wasn't one on my passenger's side - thus my question.

The shape of the parts makes me think that they might be intended to be inserted as a bushing/spacer after the fact on an as-needed basis? If not, why not just make it in a conventional simple round washer configuration?

I'll be ordering a pair today, and I will install them as the final step, when and if I end up seeing a gap which they need to fill.

Again, thanks - DM

If memory serves, it is a cam that you rotate to hold the foam tray liner down and out of the way of the transmission arms.

Ahhh - That makes sense!

You should be able to get the twist out (or most of it) by twisting it back the other way.
Heat the clamshell with a heat gun before you twist it back.
Heat it slowly get it good and warm so you can feel it with the palm of your hand.
This will encourage the metal to go back to its proper shape and will also greatly reduce any chances of paint cracking.

That's an EXCELLENT idea - Thanks!

No problem
When you twist it back twist it a little then let it come back then twist it again but a little more.
Then let it come back again keep twisting and letting it relax but twist a little farther each time.
You should eventually get to the point that you think you have twisted it to far.
But metal has memory and spring back so doing it this way along with heat you should be able to get it very close to what it was before it got twisted.

Let us know how it works out.

For sure, will do. But it'll likely be a while since the car is now off the road for the winter.

So I have a couple of months ahead of me to leisurely sort it all out.

Cheers - DM
