Fitting new reFittingar quarter window seals

Fitting new reFittingar quarter window seals

I really struggled installing these seals, they are a real barsteward to fit and there are a few tricks that are not immediately obvious.  So, I have decided to share "my" method, it may differ from your method, but it works, so please if you've done it a different way, that's fine, so long as it works for you.

 

Firstly tools I used:

 

Nylon hammer

Razor blade

Plastic trim tool set (Ebay - less than $2)

Sharpie pen

Hole punch tool

 

Plastic trim tool set

 

Nylon Hammer

By far the most difficult and most important part of this installation is getting the 'kink' part of the frame installed correctly.  If you don't do this, it will fail, when you install the interior 'U' trim, as the pressure will pull it back out of the frame and you'll have to start over !!  Not funny, trust me, I know...... it really pisses you off !!

 

So, the basic method is as follows:

 

I won't go into removing the old glass in detail, but if you haven't yet done this, beware of the retaining pin, that holds it in behind the B pillar rubber seal, if you go pulling and then pull harder because it won't budge, it will eventually shatter.........I know.......I just know OK.  There is just one pin and it is towards the top of the B pillar.

 

If you have fitted the metal B pillar glass channel, remove it.  You will see why later.  Take the seal and first, fit the lower horizontal portion into the chrome trim, this is generally a good fit and shouldn't need trimming, just ensure it is a nice fit and you have pushed it into the recess of the chrome trim.   DON'T TRIM THE SEAL AT ALL YET AT THE B PILLAR END.

I found the next bit crucial if you want the seal to remain in place.  You need to take the razor blade and trim the seal, on the inside edge, where it sits in the kink, otherwise when you bend it to fit, the inside edge splays out and makes it virtually impossible to fit into the frame.

 

Just mark the area where it kinks, and shave off the edge.  Don't worry, it won't affect the seal, or be noticeable once installed.

You are now ready to start installing the seal into the frame.  Don't do this in isolation, push the interior 'U' trim into place on the inside, at the same time, working a few inches at a time, this will ensure the seal fits correctly and means you find out right away, if something isn't right, rather than wait till after you thought you'd finished !!!  Use your plastic trim tool, to start pushing the seal into the frame, starting at the very bottom.  Work a couple of inches and you'll almost be up to the kink area, then stop and go about 3 inches above the kink and start working back down towards it, pushing the rubber into the kink at the same time.  It is vital that you now ensure the interior 'U' trim, is fitted correctly and snugly and as it should be, use your nylon hammer to tap everything into place and don't move on until you're happy that this area is fully fitted and won't pull out later.

 

 

                                                I used this tool, it takes quite a bit of force to push the seal behind the frame.

 

 

                                                                   You should now have something resembling this

 

So, now you're happy with this area, go ahead and work the rest of the seal into the frame work up towards the B pillar.  Just work it slowly and remembering to also fit the interior trim as you go.  Stop every 6 inches and give the seal and trim a few taps with your hammer, to settle it into position.

Once you get to the B pillar, you'll need to trim the seal.  I just used my razor blade for this, it was easy.  You need to judge where to cut for yourself, but for obvious reasons - don't go cutting I too short !!!!

 

 GEDC2062.JPG

 

Once you have the seal in place, pat yourself on the back, go and make a coffee and rest your hands, because they'll most likely be killing you from all that pressing in of the rubber !!!

 

The next bit might differ from other people's methods, but trust me, it works and it makes life easier.

 

Basically, rather than fit the B pillar glass channel and rubber to the car and then fit the glass.  Fit everything TO the glass, then the whole lot to the car in one hit.

 

So, take the metal channel and temporarily refit it to the frame, with a couple of screws, then fit the new rubber piece and centre it between the other seal, you'll notice the outer bit of rubber will need to be trimmed, do it later when the glass is fitted, so you know it's correct.

The reason to fit these now, is to mark for a new hole, for the glass retaining pin, as the holes in the new rubber are most likely not in the correct place !!!  So, go ahead and mark where the pin would go through the rubber.

 

Then take your hole punch tool and punch a couple of new holes for your new split pin (not supplied).

Now fit everything to the glass, including the opening handle (if it was removed).  The pin is inserted from the inside, as shown, but I don't think it would matter too much which way !!

 

                                                                                 Scuse the grubby fingers !!

Now carefully push the glass into position on the B pillar, paying attention to the rubber seal sitting correctly. Once inserted, whilst holding the glass, reattach the opening handle to the C pillar (thus ensuring the glass won't fall out).  I did mine without a rear window, so it was simple, but if you have a rear window installed, you might need someone in the car to help out.

Now, on the inside of the car, pull back the B pillar rubber trim to reveal the metal channel and the holes to secure it, using the self-tapping screws.

              Refit the four screws and push the rubber seal back into position, then trim off the excess rubber on the outside.

 

                                                                                            Hey Presto.....You're done.... Congratulations !

Does anyone use a little spray silicon lube on the rubber to make things easier ?

 

On seals that slide into a groove such as at the back of the hood it make a tremendous difference in the effort needed to slide the seal into place

Silicone spray is my standard routine for rubber gasket installs.  I found it much easier to install the pinchweld ("U" trim) after the the rubber gasket install.  The pinchweld holds the gasket in place.  And finally the gasket will distort much less if it is installed first at the kink and worked to both ends--the same procedure used by first installing door gaskets at the upper corners and working towards the bottom.

Thanks for that.

This is great...thanks for the detailed pics.  I started this project recently but gave up when I couldn't get the seal inserted in the top horizontal run torward the B pillar.  I was doing well until then.  Any particular tricks or advice about that section?

Hi Tim.  You need to buy some of the plastic trim tools.  It gets really tight along the top edge, you just need to keep pushing the rubber in behind the frame.  It is so tight there, that your hands will be hurting by the time you've finished.  You'll also need to trim the rubber before you hit the B pillar or it will be virtually impossible to do.  Just use you best judgement when trimming.

Thanks for the guidance.  My hands sure were sore when I tried before!  Question- Will the rubber edge nearest the headliner only be held in by the push on trim?  In other words, will it hang down until I push on the trim?  Thanks again for your help.

It shouldn't hang down.  It should be sitting in the frame.  As long as you've pushed the 'lip' in, from the outside, then you should be able to easily push the rubber up into the frame on the inside edge and then yes, the U trim will hold it in place.

Great.  New genuine BMW seal on the way from BluntTech, so I will soon give your approach a try. Thanks again.

Thanks for a detailed and thorough article!

Have you ever removed the chrome strips that sit immediately below that window? I'd appreciate any information on that subject.

Thanks again.

Hi Larry,

 

Yes, I removed EVERYTHING off the car during a full resto.

 

The chrome strips are simply riveted on.  So, just drill them out and use new rivets to replace it.  Don't forget to put a smear of body sealant over the new rivets afterwards and also a good splodge in the bottom inside corner of the B pillar, is probably a good idea too.

I'm having a devil of a time with these seals. I tried Dawn liquid and Silicone spray, but can't get past the kink/corner. After trying to push the lip into the flange from the outside of the car I reversed my method and tried pushing the seal in from the inside of the car after I had rolled the seal lip into the flange. I have the tool pictured in the article. These seals just don't want to fit down in that frame. Very frustrating. Shouldn't be THAT hard. I already did the door seals so I thought I had a leg up on this job.
