I posted this on benzworld so I am putting the link below. Hopefully I am not violating any forum rules. If I am, please delete this with my apologies. I know many of you do not go to both forums. I am hoping someone will be able to give me some help!

Cut & paste...

Sounds like the system is low on fluid OR the emergency opening screw on the pump is backed-off & not allowing for enough pressure to move the top.

Ok, here is the copy and paste: BTW, M.B. DOC-thanks for the torsion bar info on the w163. A buddy and I changed out the cat on the family vehicle a couple of weeks ago.

Everything is pretty much in the movies, but here it is also:

When opening, the shelf will not raise itself. I have to manually do it. The "wings" on the side usually get caught on the roll bar and so I have to make sure they are clear. You can also see that the "wings" stay up and that there is a large space between the shelf and the trunk lid. I attached a picture. I might be missing a cable or the cable is in the incorrect place.

When closing, the same thing with the shelf. It need to be manually moved. Also on the passenger's side, the hinge gets caught on the metal bar that moves down. You can see me fonze it to get it to clear.

If you can help me out with this, I would really appreciate it. I rarely put the roof down because of this and that makes so sense when owning a slk. Sorry about the shakey video and the grunts of disgust!

Hydraulic fluid is full and all movable parts have been sprayed with silicon spray.

Am I correct in assuming the only place to fill is the reservoir located in the trunk?

I straightened out the long metal piece in the picture last night. The shelf would then not move. This morning I figured out it was because the shelf was catching in the area I indicated in black. The cable (yellow arrow) seems very loose and slips out from between the 2 pulleys. It seems like the entire system needs adjustment, but there is one part that is not working at all. The second part of the shelf is not raising up at all (in blue). Does anyone know what moves this? Am I missing a cable???

I just check this. Both look good.
