Good job Mini68. I was contemplating drilling out the rivets and the detergent bit. I will give it a go tomorrow.

Mini68 you are the man. I started on the quarter vent windows after 11am today, practiced first, changed over from detergent to conditioner for less suds, done both sides. All completed and having lunch by midday. Piece of cake this way. I did use pieces of string at certain spots to keep it all in and no cutting is required. When I'm on the road I will venture down to the Island and shout you a beer.

Nice work Minicooper4me. I'll see if I can get the left side done today or tomorrow.

Yep, I have same situation with LH door, I was thinking of using sika flex to glue the vertical rubber flat to the frame as the 3 washers pull through the rubber and make the 1/4 vent difficult to close again.

Glue would be ok but I used the rivets that came with the rubbers and it came up ok. i thing it would need more than glue though. I guess normal rivets would work as well.

I too have started this job. I didn’t find it too difficult just working along prizing the rubber into channel with a nylon trim tool and fingers. I sprayed a little lanolin into the channel too, which may have improved my chances.

On the top pivot point, there is a pressed rivet, should there be a metal washer or nylon washer between the door frame and quarter vent flange?

On mine there’s quite a gap and the quarter vent can move up and down at that point. I think it effects the operation of the window as it always binds on the lower rubber... help

Have also just replaced the rubber seal. Didn't have any problems with it either.
The rivet that acts as a hinge for the top pivot point 'should' have a nylon washer. Only one side of my car has a washer but on the other side, there was not much of a gap so I didn't bother replacing the rivet and washer.
I bought 2 rivets and nylon washers from Mini King recently but didn't use them. The rivet is part no DXR412 but the washer isn't shown in my parts book.
By the way, make sure the nyloc nut and nylon washers on the bottom pivot spindle are tightened enough to resist turning too easily, or the 1/4 vent will swing closed while driving.
Binding on the lower rubber edge is also an occasional problem too.

Really. they are easy to do I have done at least 10 over the years. I am doing 2 in about a month. Use lubricant and take your time it takes about 10 mins if you have the correct rubbers .You may need to soften the rubber, try making new hydro lines then you will know what a difficult job is. 1/4 vent rubbers easy peasy.

Don Boye did a great job on the design ,they used to take about 3 mins or less to do on the production line.

I bought some nylon washers from jaycar that are pretty close to the size. O/d 10 I/d 4 and 1mm thick. I cut a slot in them and forced them into the gap with smooth pliers. Nice touch, and it keeps the vent vertically located.

Thanks Allen, I do remember Dad telling me he had quite a lot to do with the Aus windup doors and quarter vents along with Chis Rogers. They are a very clever design in that they managed to add a quarter vent AND a windup window to an extremely narrow door ....and yet still retain the door pocket.

We had a few Minis in later years and I remember Dad could disassemble the locks and door internals almost blindfolded and our Minis always had the smoothest window winders and neatest closing doors.
