Who can Identify this MAC tools vintage specialty socket: Bezel wrench?

[madprofessor]

I have tried searching the internet and pouring over lots of old MAC catalogs with no luck on this. It looks like an instrument or switch bezel wrench. Anybody?

BTW, when did MAC stop printing Sabina on their tools?

 

[ClineWrench]

Very interesting. Never seen anything like that before. Looks almost brand new?

 

[Plombob]

Welcome to the board! I'd guess you are right about the purpose of the socket. I'm surprised its not deeper to clear the switch handle. If you search for one of my threads in this section, I recently found a similar tool for switch bezels.

 

[madprofessor]

Very interesting. Never seen anything like that before. Looks almost brand new?

Yes, it appears to be unused.

 

[ClineWrench]

What's the part number on the tool?

 

[ClineWrench]

You know I was thinking that maybe it's a socket to turn an input start on a transmission. I've never needed one mind you and not sure why one would need one, but I suppose its possible. It would explain why it looks like spline like.

 

[madprofessor]

The only number printed on it is 9D 7437. It doesn't seem consistent with most MAC part numbers.

btw, when did mac stop printing sabina on their tools?

~1979.

 

[ClineWrench]

Yeah this is a real Scooby do mystery right here. When googling that part number it comes up with zilch.

 

[ClineWrench]

Is it just me or does the MAC stamp not look like any typeface I've ever seen Mac use before?

Also, what drive is it. It looks like maybe its a half inch drive.

Military??

Aircraft??


skip

 

[Murphy4570]

Yeah that is definitely something specialty. Could possibly be part of a larger specialty tool set for something specific in aviation or military, like skip mentions.

 

[madprofessor]

I have 1952, 1953 and other catalogs and very few tools show Sabina under the logo even then. I must admit, lbgradwell, that it seems you are correct in stating that MAC printed Sabina on tools until 1979 though. I had thought that the Sabina marking was an indication of the date of manufacture. The 69-70 catalog still has it on a few of the specialty tools.

The MAC logo on the other hand does use this same typeface in those catalogs. In the 69-70 one they start using the rounded top logo but on the tools with Sabina they still use the flat top logo.

It is 3/8" drive.

 

[ClineWrench]

Center cap horn bezel tool maybe? I want to say the old Pontiac's or maybe it was Chryslers that had a similar pattern on the center cap of the steering wheel.

I suppose that's a possibility.

 

[Bigplum]

The splines look like the inside of a ratchet , so maybe some torque multiplier thingy missing all the gubbins ?

9D 7437... i do not know, but the 7437 gives me a little suspicion that it might be a Ford dealer tool involved with transmissions. 7000 series parts are transmission, in Fordspeak, and the prefix would be a code for a particular trans. Ford for many decades has numbered specialty tools by the part number having a relationship with their function.

Does it fit the back of your Rolex?

 

[kythri]

It really does look like it's missing something - not just the splines, but in that first picture, you can see a recessed ring inside, right above those splines - kinda like a retaining ring would fit in there.

 

[j-guenth]

The part # 9D 7437 could be a Catapillar Part number. Could be used for transmission shaft, camshaft, and/finals shaft.

 

[madprofessor]

I hadn't considered that it could be a part to something else. That would explain it not having a proper part number. I think I got it from a retired MAC dealer I bought out. He had a lot of repair parts. It does resemble the input side of a torque multiplier although the smallest one I ever saw had a 1/2" drive input.

So check this out. I was checking out a local Craigslist ad and noticed on this Snap-On tool board there's a missing tool. If you look closely at the missing tool on the center left, it appears to be the right half of the "socket" you have

Realizing that this is a Snap-On board and not a Mac board like your tool, I still think there's a possibility that maybe Snap-On made a version of it too.

No on to the real question - what is this tool and whats it used for. I'm hoping someone can answer that because this is really beginning to bother me.

The tool that is missing on the SO board is an INLINE RATCHET.

 

[lbgradwell]

...on this Snap-On tool board there's a missing tool...

The missing tool is just a Ratchet Adaptor. A model L672 to be precise...

 

[madprofessor]

The MAC ratchet adaptors I have seen are much more compact than this. The OD is 2-3.16".

 

[madprofessor]

I listed it on eBay. https://www.ebay.com/itm/3658617611...Ic83gp/LglEMwASJN8b42BZFQ=|tkp:Bk9SR_ypy9WpZg
One person claims it is a heavy machinery oil cannister wrench, possibly Deutz. No evidence was provided.

 

[mikedodge]

It looks like something is missing. With the splines that small and close it seems like at the very least it's something that wouldn't be that tight or else it would risk stripping.

 

[Snaparxon]

Not aware if Mac ever made tools for Caterpillar but that is the numbering style (9D7437) Cat uses.

Edit: I see j-guenth has already said that in post 19 above
