help with w124 rear hatch glass TRIM removal - Page 2 - PeachParts Mercedes-Benz Forum

looking at the cross section of the seals, i get it now. That's why I was asking if the rear glass is installed like the windshield...which doesn't use that system and is just sealed bonded in place, while the trim upfront is held by clips attached to the bodywork, and a rubber gasket/lip just attaches to the trim.
Only question now is: Is the trim installed LAST as a means of locking everything in place, it would be the most logical approach, as one can install the glass/rubber seal while the rubber part still has enough room to be adjusted via the cord.

Follow up question... what type of cord did you use? thanks

I think it was made clear by engatwork - install the seal on the glass, install the aluminum trim into the groove in the seal, install the assembly. I lube the seal with dish detergent - it is slippery and washes off easily.

I suggest a new, factory, not aftermarket, seal.

Any cord about 3-4 mm in diameter will work. I use some cotton cord that I coated with candle wax - it makes the cord slide easier. Pull the coed parallel to the glass.

Cool! thanks! I think that's all the info I need.

just have to source a seal before anything else. thanks again!

Just checked the price for these seals - p/n A1246701939 & A1246702039

Works out at £220 for both seals - that's $350 by my count

there are 2 seals?!

I think blage is referring to the rear side window seals (go back to his earlier post - #13). There is a single seal for the hatch window.

oh well, its an ill wind......lol
while i'm being helpful

50 on the diagram is the seal p/n A1247400078
17 is 'frame' p/n A1247400056
8 is 'window frame left' p/n A1247450155
11 is 'window frame right' p/n A1247450255

#50 is the seal for the hatch. #17 is the seal for the glass. M-B often calls this type of glass seal a "frame".

aaah - spotted

How obvious, calling a seal a 'frame', and also calling a frame a 'frame'....

cheers!

hmmmm... is the removal of the STEEL window frames (parts #8,#11) a destructive process? can they be removed/reinstalled on their own?

vince · #28 02-26-2011, 06:56 AM

I thought I had made this clear. Here goes again. Those parts can only be removed or installed as a unit with the glass and the rubber seal. Also, they are not steel; they are aluminum.

sorry... haha... as an industrial designer... it doesn't make sense to me that everything gets installed ON/WITH the glass... then the ENTIRE assembly fitted to the hatch. What does make sense to me, and if I were to design such an installation: Install rubber on the glass... fit THAT sub assembly to the hatch...having at least a little clearance/give... then when everything is snug on the hatch...install the aluminum trim to LOCK everything in place. I think the purpose of the trim is to "spread/expand/lock in place" the rubber "frame". If it were installed before fitting the entire assembly on the hatch, then the rubber would have already been "expanded/spread" making installation on the hatch doubly difficult if not impossible to install.

Then again... i didn't design this system... and i have not done this on this car. So i definitely could be wrong.

I'm not starting a fight or anything.

It's the ID in me that needs to be convinced, no offense meant bro.
That was my final question... IS it a DESTRUCTIVe PROCESS? removalm of the trim when everyting is in situ.

There has got to be a non destructive process and a simple/reversible installation procedure... MB engineers are known for this sort of thing.

Non destructive way is to take a razor blade to cut the old one where you can free up the glass and trim. The part that you don't want to destruct is the trim piece. If you ever use the string method to pop one back in you will see the beauty of the design.
