How I put convex glass into my cab door mirror.

I tried to tighten up my loose passenger door mirror recently, by tightening the bottom cap nut and unfortunately snapped off the post. So I bought a new cab door mirror from A. Schofields as they say it is top quality and has longer thread than other repro mirrors to screw into the cab door.

The mirror came with a plain glass lens, i.e. the reflection is a simple 1 to 1. I had previously fitted a convex lens replacement to the old mirror (in 2013) like modern cars have, so the field of view is wider, and I wanted to do the same again. My bus is LHD so the off-side mirror, i.e. right hand side, is very important for me to be able to see what's there behind when changing lanes etc.

I had a spare convex glass I from the pair I bought from an EBay supplier in 2013, and put this in to replace the plain glass. I could have just used the convex glass from the old mirror but I damaged the backing silver removing it.

It's a fairly easy process to do; I removed the plastic beading from around the new mirror. It just pulled out with some effort, from around the glass. It was nice and supple probably because it was new. Then I removed the mirror glass with a plastic tool so as not to damage the mirror body.

Unfortunately I couldn’t do this without breaking the glass, the same happened last time, so to be careful I wore protective goggles and gloves. It was glued in firmly with four blobs of clear sealant. As the glass is not going to be used, it doesn’t matter if it breaks any way.

New beading is the lighter grey colour.

I found with this new mirror, the fitted glass was slightly wider than the convex glass replacement, and so the new beading was a bit loose. I was easily able to re-use the old beading, from the broken door mirror which I knew would fit.

I test fitted the convex glass with the old beading to make sure it all fitted well in the new door mirror.

Next I cleaned the inside of the stainless steel mirror and just left the old blobs of sealant on. I put four new blobs next to them. I made sure there was enough new sealant to secure the glass to the mirror housing. Then I stuck the new convex glass on top fitted with the grey beading, and checked it was installed ok.

I didn't aim for a water tight seal between the glass and the mirror housing as it would probably end up more likely trapping some water in the housing, leading eventually to rust. I left it 24 hours for the sealant to cure, before installing the new mirror with the wide view, convex glass on the cab door.

I had to loosen the cap nut on the new mirror in order to fit it to the door, so I marked where it was tightened to with a sharpie pen before I loosened it, so when re-tightening I didn’t over do it!

Any comments good or bad welcome. The last mirror glass I replaced didn’t fall off after seven years, so I am pretty confident this one won’t either.
I didn't bother with replacing the near side mirror glass, I manage fine with the plain one.

That's on my list for when the deluxe bus hits the road, Mike.
Out of interest, where did you get the convex glass from?

It was a while ago when I bought them, but it was like this one I just found which look the same.
