Okay, I am finally able to sit down and type this up. Keep in mind
that it's been a week since I worked on my sunroof. Hopefully, I
haven't forgotten anything important. **Please remember that this is
concerning a '74 Super**; I believe the Supers are a little different
from "normal" Beetles. A Bentley manual will help you out, although
their procedures did not exactly match my sunroof. But, it did give
me a basic idea of what I needed to do. Oh, and I'll use the
perspective of sitting in the driver's seat facing forward (front
means toward the front of the car, left means toward the driver's
side, etc....). The best advice I can give is just to pay attention
to the way things are as you take them apart. Draw pictures or write
stuff down if you have to. Once you understand how the whole thing
works, it will make it much easier on you when you have to put it
back together.
Alrighty, then. Here goes nothin'.....
- Open the sunroof about halfway.
- The first thing to do is to remove the headliner panel from the
sunroof itself. The panel is held on the front edge of the sunroof
only, with clips kind of like those used on the door panels. It's a
little hard at first. I ended up using a small screwdriver I use
when working on my computer. I wrapped a small bit of rag around the
screwdriver (so as not to scratch the paint on the sunroof), and used
it to pry one corner. Once you get one clip loose, then you can use
your hand, and gently pull the others loose - just like if you were
removing a door panel. There are a total of 5 clips, again, along
only the front side of the sunroof. Once they're all loose, slide the
headliner panel as far back as it will go. (The panel cannot be removed
until later on.)
- Now, close the sunroof until it's open only an inch or so. With
the headliner panel off, look at the sunroof itself. You should see
4 brackets attached to the sunroof, 2 on each side. First, you want
to take off the front 2 brackets. These brackets slide along the
tracks on each side. They should be held on by 2 screws each. Just
remove the screws, and the brackets should come right off.
- Now, look at the 2 brackets at the rear of the sunroof. These are
connected to the sunroof cables. Again, each bracket has 2 screws
holding it on. Going across each bracket, from front to rear, should
be a thin strip of metal, maybe 3 or 4 inches long. The front end is
held to the sunroof by a tab, and the back end should be sitting on a
round piece that looks like a roller. Pull down on the back end, and
rotate it towards the center of the car. At about 90 degrees, the
front end will clear the tab, and the piece will fall out. Do this
for both pieces. Now, you can remove the screws holding on the rear
brackets. When the screws are loose, you will notice that there is a
spacer between the screws and the bracket itself. Remove these
spacers, also.
- Okay, the sunroof should now be free. It'll be easier to remove
the sunroof if someone pushes it up from inside the car; then you can
get a good grip on it from the outside, and get it completely out of
the car. Carefully set it on a pile of rags or something, as not to
scratch it at all.
- Now look at the opening from outside the car. On each side of the
opening you will see a track. If you look at them close enough, you
should be able to see where the cables are. Along the front edge of
the opening you will have a chrome piece, with I think 8 screws in
it. This will be the next piece to come off. Remove all the screws,
and lift the piece out. (you may have to carefully pry it up with a
screwdriver, until you can get your fingers underneath it) You
should now see the cables. In the center you should see a clip
covering the cables. Directly under the clip, is the gear that is
connected to the crank handle. The clip holds the cables tightly
against the gear so nothing slips. The clip should easily pop off;
again, use a screwdriver if necessary.
- Next, look at the tracks on each side, looking from above the
car. In the center of each track you should see 3 screws. Take out
these screws, and then pop out the rectangular pieces from the
tracks. Try to be gentle; after taking out these last screws, there
is nothing left holding them to the car. If you have reason to, you
should now be able to spread the tracks apart enough to get the
headliner panel out. I left mine in.
- Now it's time to remove the old cables. Look at one track. You
should be able to see where the track on the side meets with the
track that goes along the front edge. You want to lift up the side
track at this point, grab the cable, and gently pull it along with
its bracket out of the track. Do this for both sides. With the
cables out, you may want the check the gear. I had gotten a new one
for mine, but decided the old gear looked just fine. If you need to
replace it, you just need to pop of the e-clip that holds the gear
on.
- Before re-assembly, inspect the tracks and gear, and remove any
old grease build-up that you see. Then apply new grease to the
tracks. I just used general all-purpose black grease. Just be
careful not to get it all over the roof or worse, the headliner.
- Assembly is, as you might expect, pretty much just a reversal of
dis-assembly. One thing I didn't realize is that the crank handle
has built in stops. If you crank it one direction, it will eventually
stop, and then when you crank it the other way, it will stop too. It
didn't know this, and when I was all done, the sunroof stopped
opening with about 2 inches to go. I think what you should do is put
in the new cables, and put the side pieces and screws back in. (make
sure you have the headliner panel back in if you took it out)
Adjust the cables so that when you look across the roof of the car,
the cables line up with each other. Make sure they're forward far
enough so that you will be able to attach the brackets back to the
sunroof. Make sure the cables are in their tracks, pop the clip back
on over the gear, and (this can be tricky), put the track cover piece
back on. Attach the cover with maybe 2 screws on each side, as you
will have to take it back off again. Now put the sunroof itself back
in, and connect all the brackets. Don't forget the long metal
springs too. Now, crank the sunroof open. Open it until it is just
completely back in the roof, or until it is open as far as it will
go. Now, take the chrome cover back off the front edge, and pop the
clip back off. With the cables away from the gear, crank the handle
counterclockwise (as looking from above the car) until it hits its
stop. If the sunroof hadn't gone back all the way, now you can push
it back manually. Now, put the cables back down in their tracks, and
put the clip back on. Finally, put the cover back on, using all the
screws. Now try the sunroof again. It should close all the way, and
open all the way, and should stop before the sunroof goes back too
far. Now, close it until it's got about 2 inches to go, and pull the
headliner panel up, and reattach it onto the sunroof. Finally, close
the sunroof all the way. If the crank handle is not in the right
place, just remove the screw that holds the handle on, pull off the
handle, line it up where it should be, and put the screw back in.
That's all!! You should now have a perfectly operating sunroof.
