MCI 8 Drivers Window

Sam 4106 · September 18, 2010, 02:48:00 PM

We are trying to remove the drivers window from our 1976 MC8 to replace it with a Peninsula window. I have removed all the screws that I can find around the interior perimeter of the window frame, but can't move it at all. Is there something else that isn't obvious holding the frame into the rubber gasket? Does the rubber gasket come out with the window or does it stay in place? I looked at both the maintenance and parts manuals and don't get any help there. Have any of you removed that window in your MC8 and can offer some advice. Thanks for any advice, Sam MC8

It's been quite a few years since we installed our Peninsula driver's window, but if I remember correctly (

?) the rubber gasket comes out with the window. The rubber may be stuck to the frame. I would try running a thin putty knife around the frame to "unstick" the rubber. Make sure all the screw are out, I cut away the rubber that covers the screw heads. Jack

Just took the drivers window out on an MC9 yesterday. After the screws, it was really just held in by some real sticky glue like material and some caulking. The putty knife all around the inside mating surface worked. After that, a big screw driver from the outside got it started moving. It is a bigger job cleaning off the old glue and caulking. I haven't put the new window in yet. By the way, I just pulled the inside rubber off so I could get at the frame.

Hi Jack and Jim,
Thanks for the information. Now I have a better idea of how to procede. I had removed the rubber from the inside to access the screws and thought I could just pry and push to remove the window. No go, but with your guidance I think I will get it out. I will try later today or tomorrow. The local festival took up last night and will take most of today.
Thanks, Sam MC8

Hi Jack and Jim,
Once again you have proved the value of this board. Thanks.
I got the window out by doing as suggested to run a thin putty knife around the window. Whoever put the window in shot about a tube of clear silicone caulk between the window and the opening, from the outside. The caulk was from 1/2" to 1/14" deep all the way around. There was no way that window was coming out even without the screws. Cleaning all that silicone off the window opening is going to be fun. Is there any solvent that will get the residue off after I finish scraping off what I can? And if I can't get all the residue off, will any kind of caulk stick to the residue besides silicone? I would like to use urethane or butyl caulk instead of silicone if it will stick. I am sure going to enjoy the better ventilation that the Peninsula window will provide.
Thanks, Sam MC8

Hi Sam,I bought one of those do it all tools that saw,sand scrape and the scraper on it would work good on getting the caulk off.I can`t think what the tool is called right now and it is up in the shop so can`t go look right now.I would come over and help you but just can`t find time right now.Get that window in so we can all see it at the Midwest BusNuts Rally at Black River Falls on Friday !

How does the Peninsula drivers window work for toll booths and such? Does the screen slide away so that you can get your hand out? How are they for wind noise on the road? My stock window is noisy as anything! I was thinking a double glazing Pen window might be a lot quieter.

Brian,

I have the Penninsula windows all around & in the driver's position. No problems with wind, easy to side window and screen for outside access tolls, directing & signalling other drivers... No leaks either.
Also in a 5C.

Take care,

Gary

With the help of my wife I got the drivers window in today. I called a local contractors supply today to ask if there is a solvent that will remove silicone caulk residue and they said xylene would. They also said xylene may remove the paint and damage the fiberglass so I will be using silicone again. They had it in black so hopefully it will blend in. I can say that Peninsula windows are nice. We elected to purchase the dual pane windows and hopefully they will eliminate the condensation problem we had with the single pane windows.
Now on to identifying and fixing the last corner suspension air leak. My list is getting shorter.
Thanks, Sam MC8
