MG Midget and Sprite Technical - Door glass channel

Hello there

I thought my window had gone but on inspection it's the door glass channel that had corroded and twisted and split

Does anyone know how to fit a new channel and rubber? Do I need any special tools?

I am guessing it is just a friction and will therefore need quite a lot of pressure to push in place.

Any help with this would be great.

Thanks

Simon,

is it the channel by the 1/4 light or by the lock?
If the latter, it's easier to replace. You'll need IIRC 7/16" o/e spanner, patience and slim hands!
You should be able to get a good secondhand one from the usual suspects.

Hi Jeremy

The bit that has gone is the actual metal that attached to the glass window with a rubber seal in between. When it fitted in attached to the window winder.

I have ordered the bits but wasn't sure if there was a way of fitting it to the glass.

Thanks

Its the metal bit on this pic:

Simon,

No special tools.

I replaced mine and an important point is to get the glass in the correct position along the channel so the winder does not jam etc - just measure original before dismantling.

The rubber is a strip of flat rubber that is oversized to allow trimming when fitted.

I seem to remember putting the rubber strip, part into the channel and introduced the glass (excess rubber being on both sides of channel) and with the channel on the bench and the glass vertical just forced down on the glass edge to push it into place.
I used a little lube - can't remember if it was petrol or white spirit - once evaporated the rubber will not slide out again !

Once fitted I trimmed off the excess rubber strip.

Brilliant, thanks Richard

Sounds quite simple, my only concern is that the old one rotted off so I am not too sure of the positioning.

Great advice, thanks

I did this job on my 68 Mk111 last year.
It's possible to insert the new support channel (with the rubber in) from the end of the door and locate it on the raise/lower arms. I then slid the glass into the door using the channel in the quarter-light as a guide so it naturally drops into the correct position in the support channel.I didn't think of Richard's trick with petrol/white spirit but I helped the window down for a few weeks until "stiction" took hold.Put plenty of grease on the moving parts while you're in there. I didn't bother trimming the excess rubber as when its in the metal channel it forms an open V helping guide the glass into the right place.

hello there

I managed to get the rubber and metal channel onto the the glass but whilst messing with it in the door it came off. I then put it back on on the door and forcing the glass down onto a screw driver handle, well the metal not the glass!

Seems to have worked so far, thanks for all your help
