My Schaublin 13 oil level sight glass is so dirty I can't see the oil level anymore. Wondering if anybody knows how to remove it for cleaning or replacement.

The manual shows a cross section where it looks like a press fit with no O ring or gasket for sealing. Not sure how that works and if it can be removed without destroying it.

Glasses like that are relatively easy to install...With time they become very difficult if not impossible to remove without killing them, noy to mention that years of
exposure to light and lube oil likely has rendered the plastic hard and fragile.

My suggestion is to look of an appropriate commercial replacement...makers rarely made such parts rather buying them from vendors.
Failing that looks like a minor project to turn a piece of Lucite to size with an "O" ring groove and you will be good to go....
Just assume that if you want to get that glass clean, you will destroy it getting it out....

Thanks for the reply Ross.

I figured I would have to destroy it to take it out but was hoping I was overlooking a simple and less destructive alternative. I’m thinking a self tapping screw and a claw hammer...

Use a machine screw. Tap it. Better yet, a pair. So you can apply twist, not just pull.

If you get lucky and it comes out intact and can be re-used, a washered machine-screw in each tapped hole will then seal it. Ready for next pull and cleaning.

I would not want to reuse it
Like Ross said Brittle and cloudy
I have a sheet of 10mm lexan just for the purpose of making my own sight glasses of non standard size

Lazy, Iyam. A 10EE can use the Lexan right out of a H-F mini-maglite.

And the LEDS don't care if they have no Lexan, so the mini-maglite still works!

For the record...

I tapped two M5 threads and got the sight gauge out with a pry bar - it wouldn’t twist. I was going to make a new one but it cleaned up well and I got lazy and put a bit of thread sealant on the screws and whacked it back in. I can always replace it later now I know how it works. It’s 32 mm diameter.

Glad you got it solved. At the least fit some black oxide button heads.

Better yet, install two small grub screws. When removing (in 50 years time), unthread them and thread regular bolts.

If you google "oil level sight glass 32mm" you'll find lots of options, for example:

https://www.aliexpress.com/item/1005001349310974.html

or

Oil Level Sight Glass press-in thermoplastic | norelem.de

Application sectors: machine, container and vehicle construction, High mechanical strength, Ageing resistant, Temperature resistant to 90°C, Solvent and antifreeze resistant

norelem.de

I would order a couple and stick them in the bag of spares. That way if the next owner pulls it in 40 years to clean it, and it breaks, there's a replacement at hand.
