What tool to use

[WTXTundra]

So I’ve got a sight glass I need to remove. It’s maybe an inch wide with maybe 1/8 risers from the face. I’m waiting to hear back from the manufacturer to see what special tool the use to unscrew this but maybe you guys got a better idea.

Suggestions?

Large hammer?

Looks like a basic spanner bit or even a slot screwdriver of the proper width might work but I can't tell if the grooves are 180º or 120º apart.

Can you use a punch and hammer and tap it around counter-clockwise? But I know you are trying to use the proper tool. For that I have no idea.

I did find this spanner socket. Spanner Socket

Do they unscrew ?
If so, maybe a “Drag Link Socket”.
They come in a variety of sizes.

looks to me like a pc of pipe or a socket (carefully) ground to fit the slots would work to grip & turn them out

I have an old set of Snap on antenna sockets that might work depending on size looks something like this

Yea that socket is perfect if the size is right

Spanner nut socket of the correct size.

What’s the OD?

I can measure them but it will be a couple of days as I'm travelling. They probably have specs on Snap on site if they still make them.

Lisle also makes a few antenna sockets. The issue is that they can be kinda fragile. I have a Sunex set, that they apparently don't make anymore, and ruined one of them on a similar task.

Punch and an Ezy-Out.

I've been looking at the pic, and trying to determine what you are trying to do. Does that whitish plate with the 3 holes in it need to rotate? Or each of those three holes rotate?

If the large whitish thing rotates, a strap wrench looks like a winner, especially as diameter gets up to 8", as does a big pin wrench, assuming that is about a 3" diameter. With no sense of scale, I'm lost here.

Pretty sure the little bevels are what need to come out to replace the sight glasses--note one is missing.

Thanks, Was confused by the orientation, most sight glasses of that diameter that I see are vertical. Diameter of the big plug is what I expected for horizontal, which that pipe seems to be with sky and gravel orienting me.

A small cold chisel that has sharp edge ground flat like a flat blade screwdriver and a small hammer

Supco makes a sight glass removal tool. I would probably use a large drag link socket as mentioned above.

Google “hook spanner”. Lots of hardware like this on old machines.
(lower right)

Hint, we usually tap them with a steel hammer.

There’s a set of 4 spanners lower right. Top 2 are hook spanners, bottom 2 are pin spanners. The weird spanner adjacent to my spare 3/4” combination wrench is a face spanner.

Need to know their names to ensure you are getting what you need.
