Hour meter question

[lagerboy]

I am in the process of tearing down my Cub 169 to restore and rebuild. The hour meter is working, but the glass is fogged from the inside. Does anyone know if the glass and or retaining ring can be easily removed so I can replace the glass? Or should I be looking for a working hour meter with clean/clear glass?
Thanks

If that is the same meter that is on a Quietline and if the meter works, the lens is a easy fix. The "fog" is on the outside.

I had a non-working one to test on, so I experimented.

My first try was perfect. I used
1) car polishing compound (not rubbing compound)
2) the black bristle brush that comes with a Dremel kit
3) some gun cleaning patches
4) a 2500 rpm drill (speed is critical, not too fast, not too slow)

The brush is the one that has the bristles pointing away from the tool, not perpendicular to the shaft.

Use the brush and polishing compound first.

Then follow that with the brush driving the gun cleaning patch with compound.

Mine look like new now.

Takes 5 minutes.

Turtle Wax an a soft cloth. Turtle Wax is a polish, not just a wax. It's a gentle cleaner that works well for this kind of stuff.

Anything can be taken apart. It's the putting back together that's sometimes iffy.

My first experience with this (of many) was taking apart my dad's Big Ben windup clock one day when I was about 6. It seemed a likely candidate, given the plethora of screws and such to work on. Unfortunately this turned out to be a poor choice for exploration.

Good luck!

I know this is off topic but when I was kid I took my fathers almost new push mower engine apart to see what made it run. He came home took one look at what I had done and said " You better be able to put that back together"

Mothers aluminium polish works well.
