C70 Hardtop alignment

Post by qcbob » Sun Jan 06, 2019 1:54 pm

I allowed my top to pause in the partially open position so I could more easily vacuum and clean some areas that are hard to get to otherwise. Now, when I close it, the pins at the front (above front windshield) do not exactly align with the holes and top will not close. Is there a place to adjust these in some way. Less than 1/2 cm off, but far enough that the pin does not slide into hole. I fear something bent very slightly under the weight of the top when I left it partially open. I do not want to "force" it closed for fear of bending something, but I'm sure I can get it closed if I need to. Any advice is appreciated.

with the front section stopped short of letting the panel drop those pins towards their ports grab that panel and manually move it to where it is squarely aligned. Now close it with assistance and help it if necessary. Once closed open it and let it go down and then put it back up. The hydraulic circuits that have two parallel cylinders in them can be manually moved an then it closes oddly. If the top continues to do this then a careful check should be made to see that nothing fell into linkage and causes a drag that makes it move repeatedly to a crooked positioning.

Thank you. I was able to help it into place and it closes fine. I have cycled it a couple of times, same result - pins do not line up. I see the cylinders, but am not sure how to adjust. Especially since they have some load on them when the top is not all the way up, after which the cylinders are not so accessible (or at least I can't see them with the headliner in place). The linkage is clear and clean. I have made an appointment with the dealer, but I am sure it will be a $145 minimum and hopefully they don't the tell me parts need replacing. Any other help is welcome. Thank You!

You can use 3in1 oil and lube all the hinging points where you see it has two pieces that bend.

Lube did not make anything move. Brought to dealer :( and they adjusted plates with pins at front of top just enough so they would slip into holes at above front windshield when top pressure applied. It works pretty good (almost 100% of the time, but not quite). To get it back to "like new", mechanic said it could range from 3 to 6 hours time depending on how many places needed to be adjusted. If you adjust one spot too much, it throws off the other section, and so on. Opted to just live with it because it would probably never really be right if we starting messing with it too much. Lesson learned is to not leave top partially open for any reason as the weight is just too much.

another thing to look for is the plastic head popping off the top linkage stop bolt. open dtop to mid travel point where it is ll up in the air. If you look at right and left sides just under edge of the rear inside upholstery trim panel for the rear seat sides (inside quarter panel trim?) you will see a stud with head and lock nut. If it veers left then the right one could have lost that stud's head cover or if it goes to right then the left is the one. The stud may not be available. If not then the nut is loosened and the stud adjusted out (to the rear of car) maybe 1.5 turns to make up for the thickness of the plastic stud cover/bumper.
